One-button circuit breaker just close point precise positioning debugging device and using method

Abstract

The invention provides a one-key type circuit breaker just-in-place precise positioning and debugging device and a use method thereof, wherein the device comprises a fixed rod, a push rod, a motor andan intermediate relay; The fixing rod is used for fixing with the driving crank arm of the circuit breaker; The push rod and the fixed rod are connected with each other through a universal joint bearing; The motor drives the push rod to rotate; The two lead-out wires of the circuit breaker break are connected in series with the coils of the intermediate relay; The normally closed contact of the intermediate relay is connected in series with the motor. So that that structure of the invention is simplify, low cost, easy to operate, As long as a button switch is use, that precise positioning ofthe rigid joint point of the main body fracture can be realize, The invention avoids the deviation of the rigid point data caused by the difference of the human hand strength, ensures the accuracy ofthe subsequent circuit breaker debugging and test data, does not need to repeatedly pull up or down and insert the skid bar, and greatly improves the production efficiency for the mass production of the production workshop.

Description

technical field [0001] The invention belongs to the field of circuit breaker equipment, and in particular relates to a one-button circuit breaker rigid point precise positioning debugging device and a use method. Background technique [0002] During the production or overhaul of the circuit breaker, it is necessary to connect and debug the newly assembled body and mechanism, and the key technology of debugging is to find the just-fit point of each phase body first. Therefore, the precise positioning of the just-fit point is particularly important. As attached to the manual figure 1 As shown, in the prior art, the search for the rigid closing point of the body is to use a crowbar to insert the body drive crank arm from top to bottom and between the pins of the locking shaft, manually pry downward to make the crank arm rotate, and drive the body to close. , At the same time, connect the lead wires at both ends of the body fracture, and use a multimeter to detect the on-off of...
