Abstract
The utility model discloses a mine-used flameproof and intrinsically safe-type high-voltage multi-circuit electromagnetic starter, solving the problems that the prior high-voltage multi-circuit electromagnetic starter is unreasonable in structure, the production efficiency is influenced due to inconvenient maintenance and commutation can not be carried out on a single motor. The mine-used flameproof and intrinsically safe-type high-voltage multi-circuit electromagnetic starter comprises a plurality of box bodies distributed left and right; two adjacent box bodies are connected via a flange; the front end surface of the box body is provided with a door body; each box body is internally provided with an isolation commutation switch, two vacuum contactors and a PLC control unit. According to the mine-used flameproof and intrinsically safe-type high-voltage multi-circuit electromagnetic starter, the structure is designed reasonably and reliably; maintenance can be carried out while other circuits operate normally; the production efficiency is improved; the control system is more reliably; the functions are complete; the structure is simple; the processing is convenient; and the mine-used flameproof and intrinsically safe-type high-voltage multi-circuit electromagnetic starter is suitable for electrical control of underground fully-mechanized mining face mining machinery.
Description
Technical field
The utility model relates to underground mine use electrical apparatus control equipment, is specially a kind of mine flameproof and intrinsic safety type high-voltage multi-loop electromagnetic starter.
Background technology
At present, the 3300V mine flameproof and intrinsic safety type high-voltage multi-loop electromagnetic starter under coal mine is mainly to adopt a large body structure, and in-built all electric components form.Practice shows, this kind of mine flameproof and intrinsic safety type high-voltage multi-loop electromagnetic starter is because self structure is limit, there is the problem of following two aspects: one, owing to adopting large body structure, once break down in a certain loop, must wholely have a power failure and keep in repair, cause all devices of this starter of access all out of service, maintenance is inconvenient to affect production; They are two years old, the multiloop electromagnetism starter of this structure, two isolation reversing switches are only installed mostly, each isolation reversing switch is controlled 3 to 6 contactors, and in actual production, often run into and need certain motor to reverse temporarily, because isolation reversing switch is controlled many contactors, cannot realize allowing certain motor reversal.
Summary of the invention
The problem that the utility model exists inconvenient maintenance to affect production efficiency and cannot commutate to separate unit motor in order to solve existing high-voltage multi-loop electromagnetic starter unreasonable structure, provides a kind of mine flameproof and intrinsic safety type high-voltage multi-loop electromagnetic starter that adopts box body splicing compound mode.
The utility model is to adopt following technical scheme to realize: mine flameproof and intrinsic safety type high-voltage multi-loop electromagnetic starter, comprise the casing that some left and right distribute, between adjacent two tanks, by flange, connect, the front end face of casing is provided with a body, and in each casing, is provided with isolation reversing switch, two vacuum contactors and PLC control unit.
During work, in each casing, all there is independently PLC control system, and connect a complete hierarchy of control of each PLC control system formation by communication cable; If break down in a certain loop, during maintenance, only need this loop casing isolation reversing switch to beat to 0 and keep in repair, operation still can be continued in other loop; Each casing is all equipped with isolation reversing switch, during work, conveniently realize certain motor reversal, the function of isolating reversing switch is embodied, overcome the problem that existing high-voltage multi-loop electromagnetic starter unreasonable structure exists inconvenient maintenance to affect production efficiency and cannot commutate to separate unit motor.
On casing, be provided with two output loops that are connected with controlled device motor, each loop is connected with the motor of controlled device, is used for the opening, stop of control appliance; In this process, user is the number of flexible configuration output loop according to actual needs, and according to the number of the number determining unit casing of output loop.
Rotation place of door body below is provided with door-opening mechanism, and the quantity of casing is 1-5, and door-opening mechanism is prior art.
The utility model reasonable in design is reliable, when not affecting the normal work in other loops, can keep in repair, improved production efficiency, and control system is more reliable, function is also more complete, has advantages of simple in structure, easy to processly, is applicable to the electrical control of coal mining machine in full-mechanized mining face tool under coal mine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-casing, 2-flange, 3-door body, 4-door-opening mechanism.
