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: 1, what are the fire hazards caused by electricity in the server room?2 what are the fire hazards in the server room?: Three, should be based on the size of the project need to determine the location of the fire to determine the use of independent electric detector or non independent detectorFour, according to the specific circumstances of the electrical equipment to determine the electrical fire monitoring detector form and installation location

Q: What power equipment is needed for the motive,: As long as the hydraulic pressure machine, bearing induction heater, tooling, assembly line assembly, commissioning test bench. Large parts to a lot, such as various parts of the fixture, the assembly line to the rotary table, lifting operation, pneumatic tools, etc.......

Q: What are the characteristics of the grounding of the power system and equipment?: Security grounding - is to protect the safety of the people and set the grounding point, such as: electrical equipment shell grounding, voltage transformer grounding two times, etc..

Q: What is the installation equipment of the transformer on the power installation project: Installation of drop fuseHigh and low voltage side of distribution transformer should be equipped with fuse. High voltage side fuse at the bottom of the vertical distance from the ground is not less than 4.5m, the fuse and the horizontal distance of not less than 0.5m, in order to smooth down the fuse tube is easy to operate and fuse, axis drop type fuse with the vertical line of 15% ~ 30% angle. The vertical distance to the surface of the bottom of the low voltage side fuse shall not be less than 3.5m, and the horizontal distance of each fuse shall not be less than 0.2m.

Q: What is the specific name of the double name of the equipment in the electric work sheet? Know please enlighten me.It would be better if you had a sample ticket.: Each power device has a Chinese name and numberSuch as: Zhang Road 905 switch, Zhang road is his Chinese name, and the 905 is his numberThe line is the same

Q: Electrical equipment classification: Current carrying conductor and gas insulated equipment. Such as bus, power cable, insulator, wall bushingA device that limits over current or over voltage, such as current limiting reactors, surge arresters, etc.Transformer equipment: make a circuit of the high voltage and large current is reduced, for measuring and relay protection devices, such as the voltage and current transformer protection in order to ensure the normal operation of an electrical equipment, the operation status monitoring, measurement, control and adjustment of the equipment is called two electrical equipment. There are a variety of measuring meter, a variety of relay protection and automatic devices, DC power equipment, etc..

Q: I would like to open a company on the construction of power equipment, what needs to be prepared? (including qualification level, capital requirements, etc.) the more detailed the better: In addition to the requirements of industrial and commercial registration, there are two industry qualification requirements. Both are the higher the level, the higher the level of examination and approval department, the highest level, respectively, need to be approved by the State Ministry of housing and national home appliances. The newly established enterprises with no performance can only start from the lowest level four.

Q: What is the importance of annual maintenance of electrical equipment? What harm does not do? As detailed, urgently!: Two, power equipment testing overviewElectrical equipment preventive testing refers to the equipment has been put into operation according to the stated experimental conditions (test equipment, such as the provisions of the environmental conditions, test methods and test voltage etc.), regularly check the test items, test period ofOr test to find out the hidden trouble of the electric equipment in operation, prevent the accident or the damage of the electric equipment. It is an important measure to judge whether the power equipment can be put into operation and ensure the safe operation.With the rapid development of social economy, the rapid development of science and technology, the range of power equipment testing, equipment and technology are advancing with the times. A set of equipment "health index" including its electrical characteristics and mechanical characteristics of the two part of the contents of the groupAs a result, and can not get the power equipment in the power of the electrical characteristics of the "health value" this problem has been plagued by power users for many years. The emergence of a new condition monitoring technology solves this problem. Not only extends the powerThe concept of equipment testing, but also to fill the blind spot in the field of power equipment testing. The conventional power outage detection and monitoring technology complement each other, to provide a full range of data support for the reliable operation of power equipment.

Q: What equipment is necessary on the list of electrical engineering equipment?: Take 35KV power engineering, the need for ZGF-400kV/2mA DC high voltage generator

Q: Power equipment is required to replace the dimension, the state has no relevant provisions: This depends on the provisions of the local power supply department, generally not mandatory requirements.
