Description
Technical field
The utility model relates to electricapparatus and makes the field, is a kind of novel high-pressure vacuum contactor-fuse loop metal-enclosed switchgear.
Background technology
The metal-enclosed type high-tension switch cabinet is widely used in industrial and mining enterprises such as power plant and metallurgy, mine, petrochemical industry, machinery, weaving.Usually the main element of high-tension switch cabinet is a vacuum circuit-breaker, but vacuum circuit-breaker is not suitable for the frequent occasion of starting, and vacuum circuit-breaker has only 20,000 times mechanical endurance.
Summary of the invention
The purpose of this utility model provides a kind of device metal enclosed switchgear that frequently opens braking that is applicable to.
Metal-enclosed switchgear, it is characterized in that: the cabinet of this device is double loop, a left and right sides structure, each part comprises bus-bar room, cable vault, handcart chamber, relay bungalow, the indoor handcart of handcart is for can extract parts out, both sides, handcart chamber are provided with the track that handcart moves, be provided with fuse group, vacuum contactor, handcart interlocking device in the handcart, the fuse group is connected with vacuum contactor by cable, in cabinet, be provided with valve mechanism with the handcart interlock, handcart interlocking device is installed in the handcart, is fixed on the handcart base plate; Relay bungalow is arranged on top, handcart chamber, and the relaying protection element is installed in relay bungalow; Bus-bar room is positioned at top, cable vault, is provided with pressure release passage in bus-bar room, and current transformer, earthed switch are housed in the cable vault, and earthed switch interlocking device is contained on the case side panel; On the instrument door of device, microcomputer monitoring protective device and instrument are installed.
The advantage of the utility model metal-enclosed switchgear is to adopt the double loop structure, compares with the single loop structure, and shell dimension is little, and floor space is little, saves material.The double loop cabinet that this cabinet is arranged about being is compared with arranging the double loop cabinet up and down, conveniently vacuum contactor and dynamic/static contact are connected with bus with hard bus, with other scheme cabinet and cabinet the time, save special main bus bar conversion cabinet, made things convenient for engineering design and user to use.This device is equipped with the microcomputer monitoring protective device, is connected with the back bench control system, can realize communication function, can take remote measurement, remote signalling, remote control, remote regulating function.Because adopt vacuum contactor not need energy storage, so this device is particularly suitable for the occasion of frequent starting, the reliability height can reach 1,000,000 mechanical endurance.
