Abstract
The invention belongs to a brake component in low voltage electrical appliance, especially relating to an operating mechanism applied to DZ series brakes. It includes an operating grip, a remote control code receiver connected with an electric machine, a mechanical reducer connected with the electric machine, a driving disc connected with the reducer, one end of a lever connected with the driving disc and the other end connected with the operating grip. Its working principle: as obtaining instruction signals, the receiver can automatically switch on the power supply of the electric machine to rotate the electric machine (the electric energy is converted to mechanical energy), the mechanical reducer works to rotate the driving disc so as to drive the lever, as rotating to a set position, the driving disc closes the brake and as rotating to the other one, opens the brake, thus realizing the completion of a whole course of opening and closing the brake by remote control. It does not need artificial manual reset and opening and closing of the brake, thus safe and reliable. On the condition of not changing the size of original breaker, it changes artificial operation of the original operating grip into remote control operation, convenient to use.
Description
One, technical field
The invention belongs to breaker assembly in the low-voltage electrical apparatus field, refer in particular to a kind of operating mechanism of the DZ of being applied to Series Circuit Breakers.
Two, background technology
Circuit breaker is mainly used in the electric equipment in the protection alternating current-direct current low voltage electric network, makes it to avoid the harm of abnormal conditions such as overcurrent, reverse current, short circuit, under voltage and electric leakage, also can be used for the usefulness of Fraquent start motor not and operation or change-over circuit simultaneously.In field of circuit breakers, the DZ Series Circuit Breakers is a kind of low-voltage circuit breaker that has a large capacity and a wide range, and is various in style, common model DZ10, DZ15, DZ20, DZ25 etc. are arranged.Low-voltage circuit breaker generally is made up of contact system, arc control device, trip free device, operating mechanism, overcurrent trip, under voltage (decompression) release, shunt release, auxiliary contact, shell or framework etc., and earth leakage circuit breaker then also will increase detection of electrical leakage and movement device.Operating mechanism is the mechanism that realizes breaker closing, disconnection, and handle operation mechanism (manually), operation electriomagnet mechanism, electric motor operating mechanism, pneumatic operator etc. are arranged.At present; the DZ Series Circuit Breakers is still used manual operation handle (referring to Fig. 1); its method of operation is: circuit breaker is because of protected circuit break down (electric leakage, overload or short circuit separating brake); then operating grip is in and drags button bit to put (centre position); after fixing a breakdown through ascertaining the reason; earlier operating grip is pulled downwards to " ON ", making could closing operation behind the operating mechanism " button again ".Because the operating mechanism manual reset, the general user is in order to consider safety problem, and relevant department also all stipulate, this type of circuit breaker is installed in more than 3 meters, like this since with manual reset inconvenience extremely not only, and still exist unsafe hidden danger.
Three, summary of the invention
The object of the present invention is to provide a kind of operating mechanism of circuit breaker, replace the manual operation handle of DZ Series Circuit Breakers, it is safe and reliable, and is easy to use.
For achieving the above object, the solution that the present invention takes is: a kind of operating mechanism of circuit breaker, comprise operating grip, one remote control code receiver connects with a motor, this motor connects with a mechanical reducer, this mechanical reducer connects with a driving-disc, this driving-disc of a lever one termination, another termination operating grip.
Operation principle of the present invention is: after remote control code receiver obtains command signal, its active motor power of connecting automatically makes motor rotation (electric energy changes mechanical energy into), mechanical reducer work is rotated driving-disc, driving-disc drives lever, when forwarding a desired location to, driving-disc is combined floodgate, be separating brake when forwarding another desired location to, the divide-shut brake overall process is finished in the realization remote control.Need not to reset manually and divide-shut brake, safe and reliable.The present invention changes the manual operation of origin operation handle into straighforward operation under the situation that does not change former circuit breaker size, use very convenient.
Four, description of drawings
Fig. 1 is a DZ10 breaker operator handle schematic diagram.
Fig. 2 is the structural representation of present embodiment.
Among Fig. 2: 1, remote control code receiver, 2, motor, 3, mechanical reducer, 4, driving-disc, 5, lever, 6, operating grip, F is the operating grip stroke, and the X line position is a closing position, and the Y line position is the separating brake position.
Five, embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is remake description.
Referring to Fig. 2, a kind of operating mechanism of circuit breaker comprises operating grip 6, one remote control code receiver 1 connects with a motor 2, this motor 2 connects with a mechanical reducer 3, and this mechanical reducer 3 connects with a driving-disc 4, this driving-disc 4 of a lever 5 one terminations, another termination operating grip 6.
The remote control distance of present embodiment is a 50-80 rice, and motor uses power supply: 12V, electrical consumption electric current≤100mA, and mechanical reduction is 10 rev/mins by 2000 rev/mins of decelerations.
