Abstract
The utility model relates to a longitudinal rotary indoor vacuum circuit breaker which is composed of a three-phase polar column part of the vacuum circuit breaker, which is longitudinally installed and can be rotated, an operating mechanism part, a rotating device part and a hand vehicle frame part, wherein, the three-phase polar column is installed in the middle of a hand vehicle frame in tandem arrangement, and can be rotated in 90 DEG around a rotating shaft of the hand vehicle frame under the operation of a rotating device. When the three-phase polar is rotated in 90 DEG from an upright position, a level position is obtained, and a visible isolated fracture is formed. Thus the circuit breaker has assembly functions of deciliter and isolating circuit. The utility model has the advantages of compact product structure, low cost, simple operation, convenient overhaul and maintenance. The utility model is especially suitable for matching with a switch cabinet.
Description
Affiliated technical field
The utility model belongs to high voltage electric equipment device technology field, relates to a kind of indoor vacuum circuit-breaker that is used to protect and control high-voltage electric system.
Background technology
The mounting structure of known indoor vacuum circuit-breaker mainly contains fixed mounting structure (as ZN28-10) and handcart-type mounting structure (as ZN12-10, ZN68-10) two classes at present, their common feature is a three-phase pole transverse arrangement of turbo, its function singleness, obviously not visible fracture, can only lean on increase equipment (as increasing isolating switch) or other means (outer) to realize visible fracture as handcart being moved to cabinet, so both increased cost, equipment volume is increased, and repair and maintenance is also very inconvenient, troublesome poeration and have potential safety hazard.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and then a kind of compact conformation, low, the simple to operate safety of cost, repair and maintenance Vertical Rotating Indoor Vacuum Circuit Breaker easily is provided.
The technical solution that adopts is so for achieving the above object: the three-phase vacuum breaker pole in the circuit breaker is vertically arranged by front and back be installed on the handcart frame that can rotate along horizontal rotating shaft, front at the handcart frame is provided with operating mechanism, and three-phase pole and operating mechanism all can be done 90 ° of rotations around the rotating shaft of handcart frame under a whirligig operation.Vacuum circuit-breaker after improving with upper type unites two into one the function of isolating switch and circuit breaker, make it to have deciliter and the combination function of buffer circuit, need not outside mobile handcart in the operation of equipment process, only need by whirligig the three-phase pole position that is up to the standard after by the upright position half-twist, just can provide isolation fracture intuitively, eliminate handling safety hidden danger to the operator.This Vertical Rotating Indoor Vacuum Circuit Breaker easy to operate, be easy to safeguard, be particularly suitable for joining switch cubicle and use, can make the cabinet body structure of switch cubicle more become to simplifying, volume is littler, the also corresponding thus area that has reduced change, switchgear house land occupation.
