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...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing method needs to repeatedly pull out and insert the pry bar, and at the same time manually operate the pry bar up or down until the just-fitting point is found, and a circuit breaker has a 3-phase body to find the just-fitting point, which is time-consuming and labor-intensive. For mass production in the production workshop, the production efficiency is greatly reduced.

[0005] 2. This method will cause deviations in the positioning measurement of the just-closed point due to the different hand strengths of people, and the just-closed point is the basis of all subsequent debugging and test data. Any mistake will cause chaos, thus affecting the entire circuit breaker data accuracy

[0006] 3. The existing method is purely manual adjustment. When using the pry bar, once the force is too large, it will cause irreversible flaws in the transmission parts and the inside of the body, resulting in damage to the equipment

[0007] 4. The use of this method needs to constantly judge whether to apply pressure according to the on-off of the multimeter. Once it is missed, it has to be repeated, which not only hinders the efficiency of the production workshop, but also greatly reduces the quality of production and maintenance

[0008] 5. For an overhauler who has just engaged in the job or is in a bad state of mind, with this inefficient and backward method, there may be a situation where the process of finding the just-fit point is not in place, so that the unqualified data will enter the test in the later link. And when it is found that the data is contradictory during the test, it will cause rework from scratch.
