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:In order to obtain the qualification test of power equipment, the company needs to have a hard condition: The office, factory are required not less than the number of square and so on, the registered capital of the company scale is also in short, very troublesome, a pile of data. To prepare documents and construction safety license corresponding to the handle. In a word, money, have a lot of money money is easy,

Q:What is the GIS in power system: GIS has the advantages of small footprint, high reliability, high security, maintenance workload is very small, the main parts of the maintenance interval of not less than 20 years.In the Three Gorges project, the left bank power station and the right bank power station has a 550 thousand volt GIS high voltage power distribution device. Left bank power station 550 thousand volt GIS and ancillary equipment in the upstream of the Deputy plant height of 93.6 meters GIS indoor. Main transformer and 500 thousand volt shunt reactor. GIS and the main transformer and shunt reactor with oil, six sulfur hexafluoride casing connection. Room GIS upper Deputy plant roof, layout of a GIS air, oil outlet pipe and open the trap, capacitor voltage transformer, lightning arrester, air outlet, six sulfur hexafluoride overhead line connected by the casing with these devices. GIS indoor type.Indoor GIS is hardly affected by atmospheric conditions. GIS overhaul cycle is generally 15 years or more, the Three Gorges power plant GIS main parts of the maintenance interval of not less than 20 years. And AIS or H - GIS, due to the impact of the external atmospheric conditions, the aging and damage speed, overhaul cycle is short and overhaul times.

Q:What are the lightning protection measures of power system: Power system lightning protection is to prevent the atmospheric overvoltage.The specific measures to prevent the atmospheric overvoltage are: to set up the lightning rod above the high-voltage line (to prevent direct lightning). Install lightning rod (lightning, lightning protection) at the equipment to be protected.

Q:Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator: The equipment you have listed has this function. The generator and the camera belong to the rotation compensation equipment

Q:The difference between electric load and power supply capacity: There is a correlation coefficient between them, the power supply capacity = power load * demand coefficient.

Q:Maintenance of electrical equipment, security measures to ensure that what: 0, in the maintenance of the unit, the unit of the internal control components, need special inspection, is strictly prohibited to open the electronic control box.11, the unit test, in the control panel of the unit, the unit before and after cutting motor direction of head and tail of each station by one person to start and stop the operation, before the test, first of all to carry out safety checks on around the unit, after confirmation, can operate.12, in the maintenance of the power supply system, first put the cooling water system, can be maintained, so as not to cooling water into the power system.13, in the maintenance of power equipment, to check the integrity of the electrical equipment and flameproof performance, so that each equipment to meet the requirements of the standard and explosion-proof. 14, any kind of relay protection device failure, power equipment shall not be put into operation.

Q:Complete sets of power equipment life of the country what are the provisions for the aging of the equipment how to deal with, there is no standard?: Such as frequency of use, load characteristics, working environment, etc.. The service life of a certain type of equipment must refer to the specifications of the corresponding industry.

Q:What is the redundancy of electrical equipment: Redundancy is a part of the system that is repeatedly configured. When the system is in trouble, the redundant components are involved in the work of the faulty components, thereby reducing the failure time of the system.

Q:What are the two devices in the power system: Your question is somewhat ambiguous, as I understand the following: the two equipment is a device for the work of the control, protection, monitoring and measurement equipment

Q:Power equipment are 10KV or less, there is a business license, will be issued by the electrical installation (repair, test) power facilities license five and above qualifications, you do not need a safety production license ah? Urgently needed: 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
