Abstract
The utility model provides a kind of motor brake control device, and described control device is made up of major loop and control loop, wherein, major loop is opened by sky, first, second contactor, brake forms, and accesses brake after the series connection of first, second main noddle on contactor; First, second contactor other end is opened by sky and is connected with power supply; Control loop is made up of external control switch and first, second contact head coil, and wherein, first, second contact head coils from parallel connection of coils, its one end is connected with external control switch one end, and the external control switch other end is opened with sky and is connected.This device circuit is easily understood, install and easy to maintenance; Work is more reliable, greatly reduces equipment failure rate, guarantees that production safety is smooth, provides powerful guarantee for improving rhythm of production.
Description
Technical field
The utility model relates to converter steeling technology field, refers in particular to a kind of motor brake control device.
Background technology
The control for brake of current motor often adopts single contactor unicoil control for brake, such as converter inclining braking control system.In steelmaking process, converter is reinforced, deslagging, tap in these operations, and in converter inclining braking control system, contactor will frequent movement, and the action of contactor each time, all can there be certain wearing and tearing to probe of contactor, long-term wear and aging, just likely cause probe of contactor sticky dead, contactor is once sticky dead, band-type brake just will be in open mode always, and converter inclining motor cannot be braked, the device damage caused thus and life casualty accident inestimable.
Summary of the invention
The purpose of this utility model is to provide that a kind of reliability is strong, failure rate is few, the motor brake control device of stable performance.
For achieving the above object, technical scheme provided by the utility model is: a kind of motor brake control device, and described control device is made up of major loop and control loop, and wherein, major loop is opened by sky, first, second contactor, and brake forms; Brake is accessed after the series connection of first, second main noddle on contactor; First, second contactor other end is opened by sky and is connected with power supply; Control loop is made up of external control switch and first, second contact head coil, and wherein, first, second contact head coils from parallel connection of coils, its one end is connected with external control switch one end, and the external control switch other end is opened with sky and is connected.
Compared with prior art, technique effect is the variable-frequency motor control for brake adopting as above technical scheme to provide:
One, circuit is easily understood, install and easy to maintenance.
Two, work is more reliable, greatly reduces equipment failure rate, guarantees that production safety is smooth, provides powerful guarantee for improving rhythm of production.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, motor brake control device described in the present embodiment, described control device is made up of major loop and control loop, wherein, major loop comprises having time opens QL1, first, second contactor KM1-1, KM1-2, and brake MY forms; Access brake MY after the series connection of first, second contactor KM1-1, KM1-2 main contact; First, second contactor KM1-1, KM1-2 other end is opened QL1 by sky and is connected with power supply; Control loop includes external control switch WB and first, second contact head coil KM1-3, KM1-4 composition, wherein, first, second contact head coil KM1-3, KM1-4 are in parallel, and its one end is connected with external control switch WB one end, and the external control switch WB other end is opened QL1 with sky and is connected.This programme is at increase contactor, ensure that two contactors are in this control circuit, its main noddle on contactor is connected in major loop, contactor coil is then connected in parallel in control loop, by this design to improve the reliability of variable-frequency motor control for brake, reduce equipment failure rate to greatest extent, support equipment safety and stability is produced.During enforcement, described a kind of motor braking control device is installed to operation field, sky is opened QL1 to close a floodgate, control mains switch QL2 to close a floodgate, when starter motor runs, the passive contact closure of external control, namely contact head coil KM1-3 and KM1-4 simultaneously electric, now the main tentaculum of contactor KM1-1 and KM1-2 closes simultaneously, makes brake obtain electric opening.Two contactor series connection actions simultaneously, prevent when a contactor adhesion, when motor quits work, reliable breakaway braking device power supply, makes brake dead electricity, brakes immediately.Object described in the utility model can be realized.
