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:Design all equipment in the power system
Two equipment: all kinds of relays, switchgear, PLC and other control equipment.The power plant and substation: electric energy metering, remote device (RTU monitoring and high frequency cutting machine), relay protection equipment (generator, transformer, bus lines and other equipment such as protection, differential protection, distance protection, over-current protection, earthing protection), automatic line monitoring device, are now in microcomputer protection the equipment.Enterprise side: the control of power supply system, DCS distributed control PLC programmable control; relay protection equipment (mainly over current protection); reactive power compensation cabinet overvoltage protection, reactive power compensation cabinet intelligent control components.
Q:I would like to ask the power experts, according to the annual additional electricity, installed capacity
The question you asked is too big, it belongs to the category of power planning
Q:Power test equipment sales to find power supply company which departments?
Procurement is generally the Department of materials management, to find a high class, livelihood, materials department
Q:How to run a company that operates electric equipment
Or do not do other electric power equipment, but the company's other power products to pull the business on the line, at the beginning of the sale to the quality of good, and then the price is low, a long time there is profit, customers will have.
Q:What principles should be followed in power equipment maintenance
(2) the maintenance plan shall be arranged according to the unified arrangement of the power grid to improve the coordination and reduce the outage time of the equipment,. Improve operation reliability and equipment availability.
Q:Three sets of complete sets of power equipment exports what is it
As well as protection, control, measurement and other devices are assembled in a whole cabinet, there are a number of high-voltage switchgear in power plants, substations or power distribution equipment installed after the installation of the power plant is called a complete set of power distribution equipment.
Q:Warranty provisions for power supply lines
According to the "construction quality management regulations," the fortieth: the scope of the warranty and its normal use of the corresponding minimum warranty period of 2 years.
Q:What are the main interference sources of the two power system
There are three kinds of electromagnetic interference in power system: electromagnetic interference between the primary equipment, the primary equipment and the secondary equipment, and between the two devices, and the electromagnetic interference between the two devices. According to the propagation path of electromagnetic disturbance, it can be divided into conduction coupling and radiation coupling. A line in the power system of switching operation, fault, lightning strikes, transient current and voltage and electromagnetic radiation line, enter the two loop through various coupling modes, these pathways are electromagnetic voltage transformer, capacitor voltage transformer, current transformer, coupling capacitor, high voltage bus and the two cable distribution between the capacitive and inductive coupling transmission way, also have a line to the surrounding space transient electromagnetic radiation energy, is two times the equipment or circuit receiving radiation coupling way.
Q:Power transformer equipment bidding procurement are in what units
Power company or Power Grid CorpElectric power company refers to the local responsible for the sale of electricity companies, both widely regarded as the local authority.The Power Grid Corp is a company that is in charge of the construction of the power grid, and belongs to a group, but is a separate company.
Q:Power equipment are used, can help to divide some of the details
3 from the degree of importance can be divided intoCore equipment and auxiliary equipment4 from the price can be divided intoLarge valuable equipment, general equipmentPower plant and substation electrical equipment is divided into primary equipment and two equipment. A device (also known as the main equipment) is the main component of the power system, it is the direct production, electricity transmission and distribution equipment, including power generators, power transformers, circuit breaker, isolating switch, power bus, power cables and transmission lines. The two device is a device for the control, regulation, protection and monitoring of a device, which comprises a control device, a relay protection and automatic device, a measuring instrument, a signal device, etc.. The two device obtains the electrical connection with the primary device through a voltage transformer and a current transformer. The primary equipment and its connected circuit is called primary circuit. Two equipment in accordance with certain rules to connect to achieve some technical requirements of the electrical circuit called the two circuit.Relay protection and safety automatic device, dispatching automation and communication system are the two systems.
