Abstract
The utility model discloses a box type high-voltage switching equipment, which comprises a box body, a main master row, an upper and a lower isolation switch, a current mutual inductor, an operating mechanism of the isolation switch, etc. An integrative vacuum circuit breaker is connected in series between the lower end of the isolation switch on the main circuit and one end of the current mutual inductor by the master row. Since the utility model utilizes the structure, compared with the prior art, the integrative vacuum circuit breaker is connected in series between the lower end of the isolation switch on the main circuit and one end of the current mutual inductor by the master row. The circuit breaker connects with the split-combination mechanism as a whole body, the reliability of the operation is high, simultaneously, and the volume of the switch equipment is also reduced.
Description
Technical field
The utility model relates to high voltage switchgear, specifically relates to the indoor box high voltage switchgear of a kind of three-phase alternating current 50HZ sectionalized single busbar connection.
Background technology
At present, the fixed metal enclosed switchgear of existing similar box is bulky, mainly be because in the box high voltage switchgear, adopt split type circuit breaker, because its operating mechanism of split type circuit breaker links to each other with circuit breaker with rotating mechanism by connecting rod, so operating mechanism circuit breaker and body are not mounted on the same foundation member, sometimes even not that same manufactory makes, so a lot of matching problems appear in high voltage switchgear when adjustment being installed and using, directly influence the high-voltage switch electric appliance performance, finally caused accident rate in service higher.
The utility model content
Technical problem to be solved in the utility model provides the high box high voltage switchgear of a kind of reliability.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of box high voltage switchgear, comprise casing, main busbar, upper and lower isolating switch, current transformer, isolator operating mechanism etc., it is characterized in that: between isolating switch lower end on the major loop and current transformer one end, be connected in series integrated vacuum circuit-breaker by busbar.
A kind of box high voltage switchgear, described integrated vacuum circuit-breaker are VA type or VS1 type.
A kind of box high voltage switchgear, described isolator operating mechanism is JSXGN type sealing lock collar.
A kind of box high voltage switchgear, the front of described integrated vacuum circuit-breaker are provided with manual deciliter button.
A kind of box high voltage switchgear, owing to adopted said structure, and prior art is compared: be connected in series integrated vacuum circuit-breaker by busbar between isolating switch lower end on the major loop and current transformer one end.Circuit breaker is linked as an integral body with a deciliter mechanism, operation and operational reliability height, and the while has also reduced the volume of switchgear.
