Abstract
The utility model pertains to a production device for underground coal mine, in particular to an explosion-proof and safety vacuum combined switch for high voltage mine, which solves the problems of single loop combination, inflexibility and comparatively poor safe performance in multiloop combined switch, more particularly, high voltage combined switch in the prior art. The utility model comprises a box body provided with a door and an electric appliance element arranged in the box body. The box body comprises a breaker box body which is internally provided with an isolated disconnecting link and a breaker and at least a group of unit box bodies which are internally provided with a two-loop electric appliance element. The utility model has the advantages that: 1. the structure design is unique, and loops can be configured flexibly, thereby conveniently realizing any combination of loops such as 2, 4, 6, 8, etc.; 2. during production practice, standby loop can be the two-loop in the unit box body and the normal operation of other loops cannot be affected during interruption maintenance of the standby loop; 3. the control power is larger, electric appliance protection is complete, program control is advanced and performance is safe and reliable.
Description
Technical field
The utility model belongs to the underground mine use production equipment, specifically is a kind of high pressure mine flameproof and intrinsic safety type vacuum combination switch.
Background technology
Along with the raising of production technology under the coal mine, high-power coal excavation apparatus increases year by year, the corresponding quickening of the update of equipment.The control panel of many large-scale coal-cutting machineries, the single loop electric-controlled switch by original is replaced by multiloop unit switch.Multi-loop combined switch is widely used at present, and manufacturer is also more, and its common characteristic is: 1, the combined loop number is based on 4 or 6 loops; 2, the electric elements in all loops all are assembled in the flameproof cabinet.Existing multi-loop combined switch, particularly high-voltage multi-loop unit switch, the loop combination is single, dumb, and security performance is lower.
Summary of the invention
The utility model is in order to solve multi-loop combined switch in the prior art, high-voltage multi-loop unit switch particularly, the loop combination is single, dumb, and the lower problem of security performance, a kind of high pressure mine flameproof and intrinsic safety type vacuum combination switch of having realized 2,4,6,8 loop combination in any is provided.
The utility model adopts following technical scheme to realize: high pressure mine flameproof and intrinsic safety type vacuum combination switch, comprise the casing that is provided with a body and the electric elements of interior setting thereof, casing is made up of a circuit breaker casing and at least one group of unit box, isolation switch and circuit breaker are set in the circuit breaker casing, two loop electric elements are set in every group of unit box.Connect by flange between adjacent casing.Unit box is provided with 2～4 groups.Door body below is provided with door-opening mechanism.
Unique body structure form is with 1 and the packet type switch casing of a circuit breaker casing and a required feeder number of user of 2～4 groups of unit boxs splicings becoming, because of device two circuit controls electrical equipment in each unit box, according to the needed feeder number of user, again several unit boxs independently are stitched together, constitute the unit switch of required feeder number.If the user needs 4 loops, splice two casings and get final product, if the user needs 6 loops, splice 3 casings, if the user needs 8 loops, splice 4 casings.
The utility model beneficial effect compared with prior art is: but 1, the unique feeder number flexible configuration of structural design, realize feeder number combination in any such as 2,4,6,8 easily; 2, in the production practices, back-up circuit can be made standby of two loops in the unit box, does not influence the normal operation in other loop when again back-up circuit being made interruption maintenance; 3, power controlling is bigger, and electric prospection is complete, the program control advanced person, and security performance is reliable.
