Abstract

The invention relates to an integrated vacuum circuit breaker. Compared with the prior art, the integrated vacuum circuit breaker has the advantages: 1, the integrated design of a high-voltage isolating switch, a grounding switching and a vacuum circuit breaker is realized, and the above devices are sealed an SF6 stainless steel air chamber with the volume being less than 100L; 2, and the simultaneous operation of the isolating switch and the grounding switch is carried out on the same operating spindle, and reaches the interlocking requirement forcibly so as to be safer and more reliable; 3, the integrated design that an operating spindle of a switching-on/off brake and an operating spindle of an isolating grounding switch are operated by vacuum bubbles is realized to save the space greatly; 4, by combining an operating mechanism, when the vacuum circuit breaker is taken as an outgoing-line-side loop, an outgoing line side is grounded after the vacuum bubbles of the vacuum circuit breaker are switched on, thus ensuring the safety of operational maintenance personnel; and 5, the vacuum circuit breaker can be matched with SF6 products in a company and international SF6 products in the same industry for use and a cabinet unit of the vacuum circuit breaker is shortened to be 375mm in width while a cabinet unit of an original vacuum circuit breaker is 750mm-800mm in width, thus decreasing the mounting space greatly.

Description

Technical field [0001] The invention relates to power transmission and distribution equipment in high-voltage switchgear, belonging to the field of high-voltage power transmission and distribution in power systems. Background technique [0002] In the field of high-voltage switchgear power transmission and distribution, high-voltage load switch, high-voltage load switch + fuse combination appliance, and vacuum circuit breaker unit are used as important incoming and outgoing line units and transformer protection units in the field of power transmission and distribution. Usually, vacuum circuit breakers The vacuum circuit breaker unit cannot be used alone, and must be used in conjunction with the isolating switch and the grounding switch. The space of the power distribution room; in addition, because the isolation switch and the grounding switch need to be equipped separately, the cost will increase accordingly. Contents of the invention [0003] The purpose of the present ...
