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 is the power system and the power network? 2 what is the rated voltage of the electrical equipment? Why do the power system to use a variety of voltage levels? 3: Power system is a kind of electric power production and consumption industry chain, which is from generation to generation. When the "power system" as an industry name, it includes power generation, for (transmission) electricity, power construction, power design, power test, power scheduling, etc..

Q: The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!: This is a bit of a problem, because there are different levels of insulation in the neutral grounding system. Some places are determined in accordance with the graded insulation, that is, the first and the end of the neutral point of the different requirements

Q: We are a manufacturer of intelligent switching equipment manufacturers to bid in the power grid to say what is the first access to what the Department: 2 please hold valid company documents to the trade and Industry Bureau for consultation!

Q: I would like to set up a power engineering Co., Ltd., do not need to know what the scope of business: Do not need to be able to do anything! Or you can hang on to someone else's qualifications!

Q: 1, common measurement and control cabinet, what is the common measurement and control cabinet? What signals are measured? High voltage side (10kV and above) have the corresponding relay protection device, regardless of the panel or on the spot, will not be on the public measurement and control cabinet; the so-called public measurement and control cabinet is measuring what? Low voltage measurement and control? Or what, for example, thank you (power generation, power supply and distribution does not matter, can speak on the line)2, network equipment cabinet, I probably can understand, is from the equipment from various communication signals collected by the communication management unit, the output signal of Ethernet, this cabinet is the main communication management machine and switch is?3, how to locate the remote communication cabinets? What is the main role? What are the main equipment?4, why do we usually need GPS time device, what is the significance? What will happen if there is no?: The network equipment and the remote communication cabinet are responsible for the communication between the equipment and the background in the station and the communication with the electric power department

Q: How to handle the qualification test, what kind of power equipment: (a) legal person qualification and perfect organization; (two) the registered capital and net assets of 60 million yuan; (three) the last 3 years to bear the following first items listed, third project and second sub items listed in any one project, and the project quality: above 1 thousand and 330 volts voltage substation 2 or 220 thousand volt substation 5; more than 2 thousand and 330 volt overhead lines 300 kilometers or 220 thousand volt overhead line of 500 kilometers; more than 3 thousand and 220 volt cable line 80 kilometers or 100 meters above the level crossing tower crossing project 1.

Q: What is the amount of equipment used? Higher profits? Do you have any power generation companies in China?: National grid examination review will find it difficult to integrate the knowledge of many aspects of the examination, the topic is also miscellaneous, the total can not touch the law. So before the exam on the long manager to accompany the class library to do it again, the test is not so difficult to finish feeling.

Q: In order to ensure the normal operation of the power system and equipment to achieve a grounding: 2) protection of grounding: is the electrical equipment in normal circumstances, such as metal parts, such as metal shell, structural frame and the earth to make metal connection. In order to ensure personal safety.3) security is zero: is the electrical equipment in normal circumstances without the metal part of the system and the zero line connection to avoid the risk of electric shock. For three-phase four wire system of electrical equipment, must adopt the method of security zero.

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: Definition of power equipment defects: An abnormal or hidden danger of the equipment or facilities that are in operation or spare. These anomalies or hidden dangers will affect the human body, power grid and equipment safetyReliable and economical operation of the power grid and equipment; equipment output or life; power quality.
