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:No concentrator can be copied directly: Although no concentrator can directly meter reading, but reading efficiency, cost and data integrity rate and data sharing will be greatly affected, so the power metersreading general will use concentrators or negative control terminal equipment.

Q:Electrical equipment classification: Mainly there:Equipment for the production and conversion of electrical energy, such as generators, motors, transformers, etc.;Switch on or off circuit breaker, such as circuit breaker, isolating switch, contactor, fuse, etc.

Q:What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?: Obstacles: not clear, probably not normal and must be modified to be normal,If the circuit breaker parameter is not appropriate, change the parameter specification.

Q:What are the necessary equipment for power line project?: There are connection tools, such as hydraulic pliers, crimping pliers, pressing tools, connecting tube, detonation pressure tube; the last is a measuring device, theodolite, rod, etc. in addition to the measuring rod; excavation tools such as shovels, iron, hammer and so on.

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: Divided into primary equipment and two equipmentOnce the equipment is responsible for the transmission of electrical energy, the two equipment is responsible for monitoring and protection of primary equipment.

Q:What principles should be followed in power equipment maintenance: Power equipment maintenance should follow the principles are: (1) to implement the "prevention oriented" maintenance policy, so that should be required to repair, repair required good"

Q:Power equipment are 10KV or less, there is a business license, will be issued by the electrical installation (repair, test) power facilities license five and above qualifications, you do not need a safety production license ah? Urgently needed: Power installation qualification certificate: one, two, level threeLevel 1: mechanical and electrical equipment installation engineering contract one class or the transmission and substation engineering contract qualification of an independent legal person to build more than 220 thousand volt classTwo level: mechanical and electrical equipment installation engineering contract two class or transmission and substation engineering contract qualification of independent legal person (220kV and below the transmission line, the construction of the substation) twoThree level: mechanical and electrical equipment installation engineering professional contract three level or transmission and substation engineering professional contract level three qualification of independent legal person (110kV and below transmission line, substation (room) construction)

Q:The difference between electric load and power supply capacity: There is a correlation coefficient between them, the power supply capacity = power load * demand coefficient.

Q:Complete sets of power equipment life of the country what are the provisions for the aging of the equipment how to deal with, there is no standard?: Conventional equipment GB service life of 30 years, actually not to use life to replace, mainly is the national economic development speed is faster, for the replacement of aging equipment, specialized centralized auction, where their standard is used according to their own situation to the report.

Q:Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply: 6kV equipment directly in the 6kV bus out of the lead, do not consider the capacity, it does not affect the use of 380V equipment
