Quick Details

Place of Origin:	HeBei China (Mainland)	Brand Name:	CNBM	Model Number:
Over-voltage protection:	10KV 24KV 35KV

Specifications

resistance-capacitance protector is most advanced in the internally installed overvoltage protectors of vacuum switch cabinet

Over-voltage protection Combined Overvoltage Protector

Normal working terms
1.Environmental temperature: -40aa ~ +60aa;Rated frequency: 48Hz~ 62Hz
2.Altitude:< 2000m

Character

1. Maximum capacity, better limite voltage effect, more widely applicable scope, stronger tolerance , long lifespan

2. Voltage impact coefficient is 1, under the various kinds of electric voltage waveform, the voltage values are equal

3. With zinc oxide nonlinear resistors and discharge gap between the structure, make the two are complementary protected. The spark gap make the State-of-Charge of zinc oxide resistance to zero, Zinc oxide resistance nonlinear characteristics also make the spark gap action without free-wheeling in future, The spark gap no longer bear arcing tasks, and improve the service life of the product;

4. Four lines connect method, can be greatly reduce the voltage of phase, the reliability of the protection is greatly improved;

5. Valve plates and the spark gap assemble space, and mutual influence, discharge electrode is not easy to damp, be oxidated, make action value more stable and reliable.

6.Take overvoltage action techniques and fault automatically function , realize the device maintenance free, at the same time, to avoid the tedious work periodically, to solve the engineering and technical personnel to worry about the problems of the equipment safe running .

Q: The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!: This is a bit of a problem, because there are different levels of insulation in the neutral grounding system. Some places are determined in accordance with the graded insulation, that is, the first and the end of the neutral point of the different requirements

Q: I would like to set up a power engineering Co., Ltd., do not need to know what the scope of business: The manufacture, development and sale of electric power equipment, mechanical and electrical equipment, high and low voltage electrical equipment, instruments and meters, electronic products, design, construction and installation of electrical engineering, mechanical and electrical products, metal materials sales.

Q: 1, common measurement and control cabinet, what is the common measurement and control cabinet? What signals are measured? High voltage side (10kV and above) have the corresponding relay protection device, regardless of the panel or on the spot, will not be on the public measurement and control cabinet; the so-called public measurement and control cabinet is measuring what? Low voltage measurement and control? Or what, for example, thank you (power generation, power supply and distribution does not matter, can speak on the line)2, network equipment cabinet, I probably can understand, is from the equipment from various communication signals collected by the communication management unit, the output signal of Ethernet, this cabinet is the main communication management machine and switch is?3, how to locate the remote communication cabinets? What is the main role? What are the main equipment?4, why do we usually need GPS time device, what is the significance? What will happen if there is no?: The common measurement and control cabinet are generally some common control signals such as AC / DC screen, knife position, device power loss and telemetry some voltage and current value, there are no specific remote control, measurement and control device of equipment access to public control

Q: All I know is a generator, a transformer. I also want to fully understand the power system related to the equipment, from power generation to end users (enterprises, factories, they will design the equipment, production equipment is not to say, but they will be transferred to the electricity, in use is the processing equipment, such as transformer, I only know this involved) equipment, detailed list, thank you ah: Two equipment: all kinds of relays, switchgear, PLC and other control equipment.The power plant and substation: electric energy metering, remote device (RTU monitoring and high frequency cutting machine), relay protection equipment (generator, transformer, bus lines and other equipment such as protection, differential protection, distance protection, over-current protection, earthing protection), automatic line monitoring device, are now in microcomputer protection the equipment.Enterprise side: the control of power supply system, DCS distributed control PLC programmable control; relay protection equipment (mainly over current protection); reactive power compensation cabinet overvoltage protection, reactive power compensation cabinet intelligent control components.

Q: On the safety hazards of electric equipment safety: 1 prohibited in the overhead power lines on both sides of the area within 300 meters of flying kites. If the illegal flying kite behavior should be stopped at the first time and report to the power sector or local government.2 no unit or individual shall plant trees, bamboo or other tall plants that may endanger the safety of power facilities in the power line protection zones.

Q: What equipment are used in the power, can help to divide some of the details, as well as the type of equipment under the type of equipment: 3 from the degree of importance can be divided intoCore equipment and auxiliary equipment4 from the price can be divided intoLarge valuable equipment, general equipmentPower plant and substation electrical equipment is divided into primary equipment and two equipment. A device (also known as the main equipment) is the main component of the power system, it is the direct production, electricity transmission and distribution equipment, including power generators, power transformers, circuit breaker, isolating switch, power bus, power cables and transmission lines. The two device is a device for the control, regulation, protection and monitoring of a device, which comprises a control device, a relay protection and automatic device, a measuring instrument, a signal device, etc.. The two device obtains the electrical connection with the primary device through a voltage transformer and a current transformer. The primary equipment and its connected circuit is called primary circuit. Two equipment in accordance with certain rules to connect to achieve some technical requirements of the electrical circuit called the two circuit.Relay protection and safety automatic device, dispatching automation and communication system are the two systems.

Q: In order to obtain the qualification test of power equipment, the company needs to have a hard condition: Can not be directly applied for; there will be a variety of requirements for the application, including the number of test personnel configuration (to have a certificate, no evidence of personnel does not count), test equipment configuration (to provide invoices for the purchase of equipment, there is no light

Q: The difference between electric load and power supply capacity: Power consumption / power consumption of electric equipment used for electric power load.Power supply capacity of the power supply system, generally refers to the user step-down transformer capacity, such as how many kva.

Q: The cost calculation of power equipment: The cost of your equipment maintenance is calculated according to the method of replacement and maintenance

Q: What principles should be followed in power equipment maintenance: (2) the maintenance plan shall be arranged according to the unified arrangement of the power grid to improve the coordination and reduce the outage time of the equipment,. Improve operation reliability and equipment availability.
