Product Description:

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:When a fault occurs in power system, the circuit breaker tripping device near fault
When a fault occurs in power system, the circuit breaker tripping device near the fault, in order to reduce the power outage, this is the relay protection ().A, selective B, reliability C, sensitivity D, non selectivity
Q:The production and transportation process of electric power
The transmission of electric energy, which is connected with the transformer, distribution and electricity, constitutes the whole function of the power system. Through the transmission, the far apart (up to several thousand meters) linked to the power plant and the load center, the development of electricity and use beyond the geographical restrictions. Transmission and other energy sources (such as coal, oil etc.) compared to transmission loss, high efficiency, flexible and convenient, easy to control, less environmental pollution; transmission can also connect the power plant in different locations, implementing peak and valley regulation. Transmission is an important embodiment of the superiority of the use of electric energy. In modern society, it is an important energy source.
Q:The cost calculation of power equipment
Fault and professional people to do the cost of fault handling and so on, there is no fixed standard, depending on the site
Q:Power test equipment sales to find power supply company which departments?
The need to find a maintenance work area (a place called SF6, fix test area) switch belongs to them
Q:Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?
Here are a few concepts, you can check1, the network voltage, is the line or the rated voltage of the bus, which is usually said to be rated voltage, including 3, 6, 10, 35, 110, 3302, rated voltage generatorThe rated voltage of the generator is usually 5% higher than the rated voltage
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.
Q:What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the situation,
High frequency means high frequency, the rated frequency of the power system is 50Hz, the maximum range of 49.8~50.2Hz, under normal circumstances, the power dispatching department will be developed through the power generation plan
Q:Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
Generators, motors, blowers, air conditioning, transportation, lifting, etc.. Rotating machinery can be called rotating equipment
Q:The role of electrical equipment handover and preventive testing
The purpose of the test is to test the performance of the equipment to prevent the occurrence of the fault, the former is the first time after the installation of the equipment to change the nature of the acceptance test, which is run during the routine. The content of the test items are different.You check the 1 power standards will know, since you do this test should have a standard hand.
Q:I would like to open a company on the construction of power equipment, what needs to be prepared?
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.
