Abstract
The utility model provides a kind of extractable low-voltage power distribution cabinet, comprise cabinet, several control unit rooms are provided with in cabinet, bus-bar room and at least one cable vault, cabinet top is bus-bar room, middle part is control unit room, bottom is cable vault, it is characterized in that: described control unit room is extraction structure, it is connected in series by several circuit breakers and forms, electro-magnetic interlock mechanism is provided with between adjacent described control unit room, described electro-magnetic interlock mechanism is that electromagnetic mechanism and host computer connect to form Based Intelligent Control mechanism, for can be chain to adjacent feasible region, control unit room, the utility model connects to form Based Intelligent Control interlocking device by adopting electromagnetic mechanism and host computer, can realize protecting each drawer unit, in extraction, one-time contact and the branch bar of drawer unit produces electric arc and causes overstep tripping accident in the process be separated.
Description
Technical field
The utility model relates to the low tension cabinet of electric power, especially a kind of extractable low-voltage power distribution cabinet.
Background technology
Low pressure drawer-type switch cabinet, due to reasons such as its structure are simple, interchangeability is good, inspection maintenance is convenient, is widely used in every profession and trade low-voltage distribution system.At present, the drawer unit of low pressure drawer-type switch cabinet general on the market generally all needs to extract out from cabinet, if when drawer unit being extracted out when circuit breaker does not have separating brake, operating current is not by circuit breaker trip, then in drawer extraction, the one-time contact of drawer unit produces electric arc with branch bar in the process be separated, the larger then electric arc of electric current is stronger, light then cause one-time contact and branch bar to burn out, heavy then arc light to make in cabinet insulation breakdown and then single-phase earthing and three-phase shortcircuit, overstep tripping and fault coverage is caused to expand, the arc light that even short circuit produces can cause operating maintenance personnel casualty.
Therefore, the utility model proposes a kind of a kind of extractable low-voltage power distribution cabinet of improvement at this.
Utility model content
For the defect existed in prior art; the purpose of this utility model is just to provide a kind of extractable low-voltage power distribution cabinet; it can realize protecting each drawer unit, and in extraction, one-time contact and the branch bar of drawer unit produces electric arc and cause overstep tripping accident in the process be separated.
The utility model solves the technical scheme that its technical problem adopts: a kind of extractable low-voltage power distribution cabinet, comprise cabinet, several control unit rooms are provided with in cabinet, bus-bar room and at least one cable vault, cabinet top is bus-bar room, middle part is control unit room, bottom is cable vault, it is characterized in that: described control unit room is extraction structure, it is connected in series by several circuit breakers and forms, electro-magnetic interlock mechanism is provided with between adjacent described control unit room, described electro-magnetic interlock mechanism is that electromagnetic mechanism and host computer connect to form Based Intelligent Control mechanism, for can be chain to adjacent feasible region, control unit room.
Adopt above technical scheme; the utility model connects to form Based Intelligent Control interlocking device by adopting electromagnetic mechanism and host computer; can realize protecting each drawer unit, in extraction, one-time contact and the branch bar of drawer unit produces electric arc and causes overstep tripping accident in the process be separated.
Described electromagnetic mechanism is electromagnet and armature composition, and is movably installed on cabinet inner position frame by back-moving spring.
Adopt above technical scheme, the composition component number of electromagnetic mechanism of the present utility model is few, and cost is low, easy for installation, practical.
