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:What are the relevant national standards for power equipment?
The standard is very thin do not know what you want to give you some of the specific power of the main reference
Q:1 what are the main aspects of power line fire? 2 what are the main aspects of electrical equipment fire?
Five, fire control room and electrical fire monitoring detector set over 8 independent electricFire monitoring detector six, electrical fire monitoring system settings should affect the power supply system
Q:What is the definition of abnormal equipment, equipment failure, equipment failure, equipment accident
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:District power equipment installation tender, the need for the conditions of the tender unit
Install the network need to debug the SERC issued installation (repair, test) power facilities permit five level or above qualification this debugging can be tender, can be a one-time construction units and the tender requirements: business license qualification certificate (grade 3) safety production license, the SERC issued Denso (repair, test) power facilities permit five level or above qualification
Q:What is the meaning of the high - voltage high - voltage device in power system
The high cycle is high frequency, rated frequency of power system in China is 50Hz, the normal range was 49.8~50.2Hz, under normal circumstances, the power dispatching department through power planning, automatic control and other means to achieve power generation and load demand power balance. In the event of an accident, the balance can not be controlled by these means,
Q:Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
The transformer is non rotating equipment. There are a lot of rotating equipment in power plants, such as fans, fans and so on, of course, the most important is the generator
Q:Definition of power equipment defects
General defectIn the short term will not be reduced to major defects, emergency defects, although the impact of the operation but can still operate.
Q:Buildings, factories, institutions, power distribution room of the power equipment as required
In the vicinity of the power grid in the supply of power on the requirements of their own generators to ensure that the dual power supply. Factories and institutions to see what the main work, if it is steel, hospital, such as the load category one or two categories of power needs of the dual power supply. And the load such as electric furnace, easy to produce harmonics, in order to ensure the power quality of the grid, it requires the installation of harmonic elimination device.
Q:What are the provisions of the national life of the complete sets of power equipment?
. For example, according to the international standard requirements of the stage mechanical engineering life is 50 years. In fact, the service life of the equipment is related to the use of the equipment.
Q:What is the double name of power equipment?
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
