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:The two devices of the power system have those: Internal equipment:1, measuring meter, such as voltmeter, ammeter, power meter, electric energy meter for measuring electrical parameters in the circuit.2, insulation monitoring device.3, control and signal device.

Q:No concentrator can be copied directly: There are two types of remote meter reading devices in electric power generation: one is low voltage set, called concentrator, the other is called terminal. The concentrator role is the number of meter data, first by the carrier or 485 communication way to collect the equipment, and then through the cable (optical fiber) or wireless network (cdma/gprs) transmitted to the main station.

Q:Is the GIS in the electric power high voltage switch cabinet: IS is a shorthand for two conceptsThe 1 is the geographic information system.2 refers to the (GAS INSULATED SWITCHGEAR) gas insulated fully enclosed combination of electrical appliances, closed inside the main circuit breaker, isolation switch, grounding switch, bus, lightning arrester, etc.. Many power plants, substations, switching stations are made of GIS, so that the small footprint, or maintenance. With the high voltage switch cabinet or not.

Q:What are the characteristics of the grounding of the power system and equipment?: The grounding - is the need for work and set up the ground, such as: high current transformer neutral point grounding, primary voltage transformer neutral grounding, 380/220V three-phase four wire neutral grounding, etc..

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: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: Primary equipment is:The power plant and substation, generator transformer (step-up / step-down transformer), busbar, circuit breaker, isolating switch, current transformer, voltage transformer, insulator, reactor, lightning protection equipment (arrester, lightning), grounding device, electric energy metering.Business side: step-down transformer, circuit breaker, isolating switch, current transformer, voltage transformer, insulator, lightning protection and grounding device, the internal power supply generator, reactive power compensation cabinet, electric energy metering,

Q:The state of power system equipment is divided into four states: (4) maintenance status. Circuit breaker and isolating switch device in the open position, the circuit breaker can be divided, and the control switch, fuse (or switch) switch maintenance should be off line and on both sides of the grounding switch (or installed ground), and hung signs work.

Q:Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply: For 35/6KV step-down stationEach line with the 6/0.4KV transformer, or 6KV equipment (such as 6KV synchronous motor), are the load of the stationSo, there are 6KV devices, single occupancy 6KV bus on a certain line can be

Q:What is the GIS in power system: Popularly speaking, GIS is often we can see the switch station, also known as high-voltage distribution device.There are three types of high voltage power distribution equipment: the first is the conventional air distribution equipment, referred to as AIS. The bus bar is exposed directly to the air, and the breaker can be provided with a porcelain column or a tank type. This type is used in Gezhouba Dam power plant.

Q:I would like to ask the power experts, according to the annual additional electricity, installed capacity, how to calculate the amount of the necessary supporting power equipment, etc.?: In accordance with the annual increase of 90 million to consider the installation of the words, basically belong to the Chinese power market
