Description

Capacity brake controls device

Technical field

The present invention relates to electrical equipment manufacturing technology field；A kind of capacity brake applying to motor braking controls Device.

Background technology

Motor is indispensable parts in commercial production, and a lot of equipment will lean on driven by motor could run, very Many occasions need motor to brake rapidly, and present motor braking method is a lot, and such as electromagnetic brake is exactly a kind of conventional motor Braking method, and some are started, brakes frequently for motor, braking can make mechanical braking shortened equipment life frequently, So that the production cost of enterprise increases.

Summary of the invention

It is an object of the invention to provide a kind of capacity brake and control device, it can solve frequently to brake and make mechanical braking set The standby lost of life, the problem that entreprise cost is high.

In order to solve the problems referred to above, the technical solution used in the present invention is: this capacity brake controls device, including controlling Case, is provided with chopper, fuse, the first catalyst, the second catalyst, thermorelay, time continue in the case of described control chamber Electrical equipment, electric capacity, resistance and the first resistance；The chamber door of described control chamber is provided with stop button and start button；Described fuse, Stop button, start button, the second catalyst, the first catalyst and thermorelay series connection form the first contactor control circuit, Described first catalyst formed first catalyst holding circuit in parallel with start button, described fuse, the time relay, first Catalyst, the second catalyst and thermorelay series connection formed the second contactor control circuit, described fuse, the first catalyst and Time relay series connection forms time relay control circuit, electric capacity formation in parallel with a resistor parallel circuit, described parallel circuit Having three groups and connect into triangle, described second catalyst is connected formation braking electricity with the described parallel circuit connecting into triangle Road, described braking circuit is connected with the leading-out terminal of motor stator.

In technique scheme, more specifically scheme is it may also is that described second catalyst and the institute being connected into triangle State to connect between the line of parallel circuit and have the first resistance.

Owing to have employed technique scheme, the present invention compared with prior art, has the beneficial effect that due to this Bright is the leading-out terminal access braking circuit at motor stator, and its braking is circuit rather than machine, so frequently braking will not Cause the lost of life of braking circuit.

Accompanying drawing explanation

Fig. 1 is the control chamber front view of the present invention.

Fig. 2 is the principle schematic of the present invention.

Detailed description of the invention

The invention will be further described with embodiment below in conjunction with the accompanying drawings:

Capacity brake shown in Fig. 1 and Fig. 2 controls device, including control chamber, is provided with circuit breaker Q F, fusing in the case of control chamber Device FU, the first catalyst KM1, the second catalyst KM2, thermorelay FR, time relay KT, electric capacity C, resistance R2 and the first electricity Resistance R1；The chamber door of control chamber is provided with stop button SB1 and start button SB2；Fuse FU, stop button SB1, start button SB2, the second catalyst KM2, the first catalyst KM1 and thermorelay FR series connection form the first contactor control circuit, and first connects Tentaculum KM1 formed first catalyst holding circuit in parallel with start button SB2, fuse FU, time relay KT, the first contact Device KM1, the second catalyst KM2 and thermorelay FR series connection form the second contactor control circuit, fuse FU, the first catalyst KM1 and time relay KT series connection forms time relay control circuit, electric capacity C formation in parallel with resistance R2 parallel circuit, and Connection circuit has three groups and connects into triangle, and the second catalyst KM2 is connected formation braking with the parallel circuit connecting into triangle Circuit, braking circuit is connected with the leading-out terminal of motor stator；The line of the second catalyst KM2 and the parallel circuit being connected into triangle Between connect have the first resistance R1.First resistance R1 is the size of regulating brake force square for regulation resistance, its effect, and resistance R2 is Discharge resistance.

During starting, pressing start button SB2, the first contactor control circuit obtains electric, and the first catalyst KM1 controls motor to be risen Dynamic operation, time relay control circuit obtains the electric coil adhesive making time relay KT, the second contactor control circuit simultaneously In the time delay of time relay KT disconnect normally open contact Guan Bi, be that the second catalyst KM2 obtains electricity and prepares；When motor to be made stops When only working, press stop button SB1, the first contactor control circuit dead electricity, simultaneously in the second contactor control circuit The normally closed interlock Guan Bi of one catalyst KM1 makes the coil of the second catalyst KM2 obtain electricity adhesive, the second catalyst in braking circuit The main contact Guan Bi of KM2, accesses the stator winding of motor by braking circuit, and motor is braked, until stall.

The parallel circuit of electric capacity C formation in parallel with resistance R2 has three groups, can be connected into triangle or star, go out with motor stator Line end forms closed-loop path, and when the motor deenergization run, the remanent magnetism cutting stator winding in rotor produces sensing Electromotive force, and charge to electric capacity, its charging current forms exciting current in the stator windings, sets up a magnetic field, this magnetic field Interact with rotor remanent magnetism, produce a braking moment opposite to the direction of rotation, make the rapid stall of motor, complete system Dynamic.

High speed, the motor of low-speed running all can be braked rapidly by the present invention, and energy loss is little, and equipment is simple, can be used for making Dynamic place frequently.
