Product Description

Introduction to the structural characteristics of solid insulated ring main unit movement

Use of environmental conditions
1. Suitable for indoor or outdoor;
2. Surrounding air temperature: indoor -10ºC+25C,outdoor -60C+60C;
3. Relative air temperature: daily average not greater than 95%, monthly average not greater than 90%;
4. Altitude not greater than 2000m;
5. The surrounding air should not receive dust, water vapor, salt spray, corrosive gases or flammable gases obvious pollution; outdoor type can be used in more severe environmental conditions;
6. The installation location without severe vibration, seismic intensity does not exceed 8 degrees;
7. when the above use of environmental conditions can not meet the use of requirements, by the user and the manufacturer to negotiate;

The action of solid insulated ring network cabinet consists of several important parts such as vacuum interrupting chamber, solid insulation system, three-position knife gate, operating mechanism and so on. Meanwhile, each part has its own functional characteristics:.

1.Vacuum circuit breaker.
The main component in the vacuum interrupter chamber of solid insulation ring network cabinet is vacuum circuit breaker, which can open short-circuit current and is used for overload and short-circuit protection of circuits and electrical equipment. Because of its contact distance is small, the burning arc time is short, the contact breaks the fault current when the burns are slight, the operation energy is small, the action is rapid, but also has the advantages of small size, light weight, protection workload is small, waterproof and explosion-proof, operation noise is low, and so on. It is an ideal circuit breaker to replace oil circuit breaker and SF6 circuit breaker, widely used in electric power, metallurgy, communication and other work in high frequency heating and other power distribution systems. Vacuum circuit breaker interrupter is the key component and heart of vacuum circuit breaker, basically completes the main function of the circuit breaker.

2. Solid insulation system.
For the solid insulation system of solid insulated ring network cabinet, the solid sealing pole molded by APG process is used to encapsulate the current-carrying conductors such as vacuum interrupter chamber, upper and lower outlet blocks into a whole. Switching isolation is installed in the cavity of the sealed pole, so the solid insulation method is the main insulation method for phase-to-phase insulation. The single-phase bus can be expanded planning, ending the wireless expansion of the utility unit.

3. Three-position circuit breakers.
All the switchgears are equipped with triple working gate and knife switches. The triplex circuit breaker is built into a fixed sealed column along with the main switch. The three-phase linkage can be operated in three directions: end of operation/isolation/grounding. Mechanical interlocking is selected with the main switch. The three-phase circuit breaker can only be operated when the main switch is in the break position, and the other three-phase circuit breakers can end the interlocking with the earth position. The grounding side hole is locked when the circuit breaker is in the operating position; the operating side hole is locked when the circuit breaker is in the grounding position.

4.Operating Organization.
The operating organization of the circuit breaker of the solid insulated ring network cabinet is a tension spring operating organization, which is characterized by simple structure, reliable action, small size and no protection. The closing power can be adjusted up and down according to user requirements. The mechanism can be manually stored energy, manually opened, manually closed, and can also be stored energy power off, which is convenient for users to operate.
