A miniaturized central handcart cabinet

Abstract

The invention provides a small-size centrally-mounted handcart cabinet, which comprises a cabinet body, wherein a switch chamber, a bus chamber and a cable chamber are arranged in the cabinet body; the switch chamber communicates with the bus chamber; the bus chamber communicates with the cable chamber; a vacuum switch device is arranged in the switch chamber; a contact box device is arranged in the bus chamber; a grounding switch device is arranged in the cable chamber; the vacuum switch device is connected with the contact box device; the contact box device is connected with the grounding switch device through a crossed connecting element. All electric chambers inside the cabinet body are in compact distribution; the connecting pipes in vertical arrangement are matched with connecting holes to realize the connection of the vacuum switch device and the contact box device, so that the space is further saved; the integral width of the cabinet body is greatly reduced; the occupied area of the cabinet body is reduced; the miniaturization effect is good.

Description

technical field [0001] The invention relates to the electrical field, in particular to a miniaturized center-mounted handcart cabinet. Background technique [0002] Existing switchgears are bulky and complex in structure. Such as: patent announcement number: the Chinese invention patent of CN203536842U discloses the miniaturization structure of a kind of KYN28 middle switchgear, although above problem has been optimized, but still can't solve the problem. Another example: the Chinese invention patent of patent announcement number: CN102916352A discloses a miniaturized fixed switchgear. Although the structure has been newly arranged and adjusted, the insulating parts and lightning arresters of the isolating switch are installed on the side of the cabinet, occupying Large space, and the vacuum circuit breaker used, the operating mechanism is large in size, the interlock is incomplete, and the width of the cabinet cannot be effectively controlled. Another example: patent anno...

Problems solved by technology

[0002] Existing switch cabinets are bulky and complex in structure

Such as: patent announcement number: CN203536842U's Chinese invention patent discloses a miniaturized structure of KYN28 central switchgear, although the above problems have been optimized, but still can not solve the problem

Another example: the Chinese invention patent of patent announcement number: CN102916352A discloses a miniaturized fixed switchgear. Although the structure has been newly arranged and adjusted, the insulating parts and lightning arresters of the isolating switch are installed on the side of the cabinet, occupying Large space, and the vacuum circuit breaker used, the operating mechanism is large in size, the interlock is incomplete, and the width of the cabinet cannot be effectively controlled

Another example: patent announcement number: CN202454952U's Chinese invention patent discloses that a KYN type switchgear also has the defects of large volume, wide width, large floor space, complex structure, and high cost.
