Resistor Elements

Over-voltage protection:

10KV 24KV 35KV


MRD series resistor is applicable to AC/DC circuit of 10V ~ 300KV, used for driving/braking/regulating motor, load, protection of neutral point and so on.

MRD series resistor are of safe product features, large thermal capacity, corrosion-resistance, high-temperature resistance, long lifetime and non-maintainance, etc., and of superiority when matched with high power motor. In power system it is widely used for neutral ground protection of high-voltage transformer, auto-tracking arc-supression coil damping of high voltage power distribution, harmonic filter and so forth.


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: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
Q:The problem of electric power equipment withstand voltage
Because of the low air pressure in the air at high altitude, at the same voltage
Q:What is the meaning of the power equipment in criminal law
The behavior of the power line that has been installed and has not yet been powered off shall be treated differently. If the stolen cut is not formally delivered to the power sector to use the line, should be handled in accordance with the theft case. If the actor knows the line has been delivered to the use of the power sector and steal cut wires, shall be designated as the crime of destruction of power equipment.
Q:Private enterprises must be free transfer of power facilities
The new user electrical facilities investment, after the investment asset is transferred to the power supply enterprise, according to the need for "business rules", the actual state of electricity contribution, interface division, maintenance management ability, after consultation by both parties to determine.
Q:Maintenance of electrical equipment, security measures to ensure that what
4, before each class must listen carefully to the previous report on the operation of the equipment, to understand the existing state of all equipment. 5, the maintenance of electric power equipment insulation must wear protective equipment, strict stop transmission system, stop transmission to a person responsible for the maintenance of switch control equipment, the switch to power and hang people work, no power "brand, and special care, strict implementation of the mine management regulations to stop electric. Only when the gas density is around 20 meters range is lower than 1%, only open power equipment, and use the same grade pencil test in cut off power supply, after the confirmation, discharge, and then can carry out comprehensive maintenance, maintenance end is correct, it can send electricity.
Q:The two devices of the power system have those
Two power system equipment:An auxiliary device for monitoring, measuring, controlling, protecting and regulating the primary equipment in a power system, called a two device, that is not directly connected to the electrical energy.
Q:Power equipment Market Overview
The first quarter of 2013, China's economy once again showed signs of slowing down, iron and steel, nonferrous metals and other raw material prices low volatility, electric power equipment manufacturing production costs at a relatively low level; at the same time by the industry overcapacity, fierce competition in the product market, a common means of low bid for corporate competition. Affected by the above two factors, the 1 quarter of China's power equipment manufacturing industry most price decline, in the electric power equipment Chinese Machinery Industry Federation statistics, 22 small manufacturing industries, there is decline in price index rose only 16 sub sectors, 6 sub industry price index.
Q:Power equipment are used, can help to divide some of the details
When drawing the main wiring diagram, the transformer, arrester, capacitor, neutral point equipment and carrier communication can be used to reflect the situation of power supply in normal and accident conditions. Electrical wiring is also known as the main electrical
Q:Electric power automation equipment
Construction and transformation of rural power grids, power plants, power plants, environmental protection, automatic control and integrated automation of nuclear power plants, technical management, etc..
Q:What is the power equipment network
State Grid procurement requirements to provide information: network card requirements are not standardized,For the national grid access card: 1, please hold valid company documents to the local GRID (NATION) business hall, consulting
