Quick Details

Place of Origin:

HeBei China (Mainland)

Brand Name:


Model Number:

Over-voltage protection:

10KV 24KV 35KV


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


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:Pre checking and checking of goods in power system
Check: the full name is a regular inspection, with the role of pre trial is almost the same as the general power system is the two equipmentGoods inspection heard, just heard of items set is the item visit orderly, convenient for production work.
Q:What is the definition of abnormal equipment, equipment failure, equipment failure, equipment accident
Exception: may be a precursor to the accident, has not yet caused the loss, the cause is unknown,Such as the normal operation of the cable overheating, burning plastic taste
Q:What principles should be followed in power equipment maintenance
(3) the maintenance of equipment should be combined with the technical renovation, and the equipment renewal plan should be made according to the defects of the equipment and the need of the development of the power network.The basic principles of emergency repair of electric power equipment should follow the principle of "selecting weight and avoiding light" and "using the signal first.".
Q:The concept of "remote message" in communication and power equipment
General electric power on the four remote, remote, telemetry, remote control, remote control, and now there is more than one remote viewing. Remote signal is generally refers to the opening and closing state of each switch, remote measurement is the voltage, current, temperature, etc..
Q:How to solve the short circuit of emergency communication equipment
Usually you see the white plate, marked with "national emergency communications," the license plate, if the following is the letter "B" at the beginning of the China Radio Association members
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.
Q:What is the concentrator of the power set
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:The difference between electric load and power supply capacity
The coefficient of demand is a comprehensive coefficient, which indicates that the ratio of the actual power taken from the power supply network and the power of the power equipment group. That is, your equipment can not be run at the same time, it is impossible to run at full capacity, as well as line power efficiency, power equipment in the actual operation of the power efficiency and other related. In fact, it is difficult to determine the above coefficients for a group of electrical equipment, not to mention the operator's proficiency, the supply of materials, tools, such as the quality of random factors have an impact on. So we can only depend on the measurement statistics.
Q:Power equipment is required to replace the dimension, the state has no relevant provisions
But more time has entrusted operation maintenance experience unit maintenance, power equipment to customers is good, one can improve the safe and stable operation of equipment, to meet the demand of a power supply section, on the other hand it can guarantee and increase operation life of equipment.
Q:Electric power automation equipment
Power grid dispatching automation, power system analysis and control, power electronics, power market, distribution automation,
