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 .

Supplier Assessment Reports are detailed on-line reports about the supplier's capabilities. It helps you get all the information you need to trade confidently with suppliers.

Q: What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?: Fault: operation is not normal, simple inspection process can be restored in time,Such as the use of electric leakage, overload caused by leakage circuit breaker trip.

Q: We are a manufacturer of intelligent switching equipment manufacturers to bid in the power grid to say what is the first access to what the Department: 2 please hold valid company documents to the trade and Industry Bureau for consultation!

Q: In the communication and power equipment in the data access to a "remote message quantity" concept, then what is called "remote information", how to define it? Thank you: General electric power on the four remote, remote, telemetry, remote control, remote control, and now there is more than one remote viewing. Remote signal is generally refers to the opening and closing state of each switch, remote measurement is the voltage, current, temperature, etc..

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 network equipment and the remote communication cabinet are responsible for the communication between the equipment and the background in the station and the communication with the electric power department

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: Is there a warranty period for power equipment?: Warranty period is not specified, is determined by the relevant test standards

Q: The difference between electric load and power supply capacity: The coefficient of demand is a comprehensive coefficient, which indicates that the ratio of the actual power taken from the power supply network and the power of the power equipment group. That is, your equipment can not be run at the same time, it is impossible to run at full capacity, as well as line power efficiency, power equipment in the actual operation of the power efficiency and other related. In fact, it is difficult to determine the above coefficients for a group of electrical equipment, not to mention the operator's proficiency, the supply of materials, tools, such as the quality of random factors have an impact on. So we can only depend on the measurement statistics.

Q: The two devices of the power system have those: Two power system equipment:An auxiliary device for monitoring, measuring, controlling, protecting and regulating the primary equipment in a power system, called a two device, that is not directly connected to the electrical energy.

Q: For example, EPS emergency power supply and so on, as well as those used in public emergencies.: The key is not the equipment problem, but to attach importance to the power emergency platform and power dispatching platformOf course, in addition to EPS lighting / power emergency power supply, there are the following emergency equipment:

Q: Pre checking and checking of goods in power system: Check: the full name is a regular inspection, with the role of pre trial is almost the same as the general power system is the two equipmentGoods inspection heard, just heard of items set is the item visit orderly, convenient for production work.
