The VBI-12 single spring operating mechanism is an integrated product specially designed for three-phase AC 50Hz, rated voltage 12KV indoor high-voltage vacuum circuit breaker operation. It is a modular functional unit design with a compact and simple structure. Reliable and easy to operate. The optimized closing function unit design reduces the closing power, which not only fundamentally solves the occurrence of failures such as failure to maintain and refuse to open after closing, but also reduces the trip power required for opening; motor energy storage unit It adopts gear transmission and compact structure, which reduces mechanical failures due to quality problems such as chains. Thereby, it is greatly improved that the disconnected motor energy storage unit adopts gear transmission, has a compact structure, and reduces mechanical failures caused by quality problems such as chains. Thereby greatly improving the mechanical life of the circuit breaker spring mechanism (30,000 times). The surface of 80% of the parts in the mechanism is treated with a special process, which greatly improves the anti-corrosion ability of the parts and ensures the consistent and stable quality of the machinery.
a. VBI-12 indoor high-voltage vacuum circuit breaker equipped with intermediate sealed ceramic vacuum interrupter, the use of copper-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 arc is restored quickly, the cut-off level is low and the breaking ability is strong.
b. VBI-12 indoor high-voltage vacuum circuit breaker overall structure of the operating mechanism and the use of arc extinguishing system in the form of the main conductive circuit part of the three-phase floor structure, vacuum interrupter longitudinal installation of a tubular installation tube, The tube is made of epoxy resin using APG process, so it is particularly resistant to creeping. This structural design, greatly reducing the accumulation of dust and then the arc chamber surface, not only can prevent the vacuum interrupter by external factors damage, and can ensure that even in the hot and humid and serious pollution environment, the voltage effect can also show a high resistance state.
c. The operating mechanism for the layout of the spring energy storage mechanism, with manual energy storage and electric energy storage function, the operating mechanism placed in the chassis before the arc chamber, the chassis was divided into five middle partition five assembly space, In the meantime, the energy storage part, the transmission part, the tripping part and the buffer part of the operating mechanism are respectively installed. The VBI-12 vacuum circuit breaker will arrange the arc chamber and the operating mechanism to form a unified whole, that is, The structural design allows the operating performance of the operating mechanism to be more consistent with the required performance of the interrupter opening and closing, reducing unnecessary intermediate transmission links, reducing energy consumption and noise, making the operating performance of the VBI-12 circuit breaker more Reliable, VBI-12 circuit breaker can be loaded into the hand-car switchgear, can also be loaded into a fixed switchgear.
d. The circuit breaker has the advantages of long service life, simple maintenance, no pollution, no explosion hazard and low noise, and is suitable for the harsh working conditions such as frequent operation.
