Detailed Instruction
■ Overview
VS1 series vacuum circuit breaker for the rated voltage 12KV, three-phase AC 50HZ high-pressure indoor switch equipment, is the introduction of Switzerland ABB technology combined with the development of the domestic industry, production capacity development and manufacturing products. The overall structure of the product for the beginning of the body and the operating mechanism of the installation of the form, the use of composite insulation structure, no pollution, no explosion hazard, high insulation level.
The operating mechanism of this series of products for the spring energy storage, you can use AC operation, can also be manually operated.

■ VS1-12 fixed vacuum circuit breaker structure and characteristics

1 vacuum interrupter
VS1-12 fixed vacuum circuit breaker equipped with intermediate sealing ceramic or glass vacuum interrupter, the use of copper and chromium contact material, cup-like longitudinal magnetic field contact structure, the contact of the electric wear rate is small, long electrical life, The pressure level of the contact is high, the dielectric strength of the dielectric is stable, the recovery speed is fast after the arc, and the horizontal level of the cutoff is strong.
2 overall structure
The main structure of the VS1-12 fixed vacuum circuit breaker adopts the form of the operating mechanism and the front and rear arrangement of the interrupter. The main conductive circuit part is a three-phase floor type structure. The vacuum interrupter is installed in a tubular insulation cylinder, It is made of epoxy resin by APG process, so it is particularly resistant to creeping. This structural design greatly reduces the accumulation of dust on the surface of the arc extinguishing chamber, not only to prevent the vacuum interrupter by external factors, but also to ensure that even in the hot and humid and serious pollution can also show a high voltage effect of high resistance state.
Circuit breaker in the closing position of the main circuit current path:
The upper receptacle 28 is softly connected to the upper bracket 27 fixed to the interrupter, to the internal static contact of the vacuum interrupter, to the movable contact and its associated conductive clip, to the lower bracket 30 and the lower outlet 32. The operation of the circuit breaker and the contact of the contact are carried out by the insulating rod 34 and the internal disc spring 33 through the circuit breaker link system.
Circuit breaker factory at the current level are equipped with dust-proof insulation tube cover, in the actual use of rated current 1250A and below the level of transport
Line must not be removed, the rated current of 1600A and above must be removed when running.

3 operating mechanism
The operating mechanism is a spring-loaded spring energy storage operating mechanism with manual energy storage and electric energy storage function. The operating mechanism is placed in the machine box in front of the interrupter, and the mechanism box of the circuit breaker is used as the operating mechanism The structure. The machine box is divided into five assembly spaces by four intermediate partitions, each of which is equipped with the energy storage part, the transmission part, the tripping part and the buffer part of the engine, the front part has the joint button, the manual energy storage operation hole, Spring energy storage status signs, combined points signs. In this way, the arc extinguishing chamber and the front and rear arrangement of the body form a whole, so that the two more consistent, reduce the unnecessary intermediate transmission links reduce energy consumption and noise, so that the circuit breaker function more reliable.

4 VS1-12 fixed vacuum circuit breaker has long life, easy maintenance, no pollution, no explosion hazard, low noise, than for frequent operation and other conditions more harsh working conditions. The circuit breaker can be fitted with a handcart switchgear. Can also be used for fixed switchgear.
