Abstract
The utility model relates to a direct current break-make pulse device for circuit breaker, including the main part, main part internally mounted has miniature singlechip and relay, and the main part left and right sides is equipped with the installation trip, and through the cooperation of miniature singlechip and relay, after the user inching or long press the button, the adjustable pulse signal of exportable 0.1-1S to the branch of circuit breaker, closing coil, avoid long-time transport voltage to lead to the coil to generate heat or burn out, reduce the maintenance and change and divide, closing coil, satisfy the field usage demand.
Description
Technical Field
The utility model relates to a circuit breaker auxiliary device field, concretely relates to direct current break-make pulse device for circuit breaker.
Background
The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. At present, switching-off and switching-on of all circuit breaker switches are carried out by controlling switching-off and switching-on coils through buttons or an external automatic system, and when the switches are normally switched off and switched on and switched off, the switching-off and switching-on coils are locked by adding auxiliary contacts, so that the switching-off and switching-on coils are ensured to be uncharged after acting. When the switch has the problem that the switch can not be closed or opened (mechanically or interlocked), long-time output voltage is output to the opening and closing coils by long-time button pressing or external automatic control, and the components and the closing coils are easy to generate heat or burn out, so that maintenance is caused in the later period.
SUMMERY OF THE UTILITY MODEL
To prior art above-mentioned defect, the utility model provides an aim at provides a direct current break-make pulse device for circuit breaker, can not long-term output voltage to branch, closing coil protection coil avoid receiving the harm, concrete technical scheme as follows:
a direct current on-off pulse device for a circuit breaker comprises a main body, wherein a micro single chip microcomputer and a relay are installed in the main body, and the micro single chip microcomputer is electrically connected with the relay and outputs an adjustable pulse signal of 0.1-1S to an on-off coil of the circuit breaker.
As an optimized proposal of the utility model, the left and right sides of the main body are provided with installation clamping hooks.
As an optimized proposal of the utility model, a button is arranged on the main body.
As an optimized proposal of the utility model, the left side and the right side of the middle part of the main body are provided with 4 contacts.
The utility model has the advantages that: through the cooperation of the micro single chip microcomputer and the relay, when a user clicks or presses a button for a long time, 0.1-1S of adjustable pulse signals can be output to the opening and closing coils of the circuit breaker, the phenomenon that the coils are heated or burnt out due to long-time voltage transmission is avoided, the maintenance and replacement of the opening and closing coils are reduced, and the field use requirements are met.
