The disc spring mechanism needs to carry out secondary wiring detection of a motor energy storage loop, a switching-on/off loop and an auxiliary loop before the disc spring mechanism is assembled with the body, but great inconvenience is brought to detection work of the secondary wiring of the disc spring mechanism due to the difference of engineering secondary drawings, inconvenient detection of plug connectors and the like, and in order to solve the problem, a disc spring mechanism secondary wire detection device is designed.
In order to solve the current situation that the existing secondary circuit detection mode cannot be used for increasingly producing tasks, first-line staff and technology and production staff consider to manufacture a detection device according to the characteristics of products, the secondary circuit of a circuit breaker disc spring mechanism is utilized to divide all contacts in the mechanism according to the on-off state and the on-off state, the contacts are respectively connected into an on-off state and a motor loop in series, and a signal lamp is utilized to indicate the correctness of wiring and contact on-off of the secondary circuit (auxiliary circuit).
As shown in fig. 1, the disc spring mechanism secondary line detection device comprises a control panel 1, an indicator light 2, an opening and closing change-over switch 3, a resistance display 4, an external connector 5 and a trolley 6. The control panel comprises a motor pressing contactor, a pressing delay protection relay, a miniature circuit breaker switch and a wiring terminal row.
The secondary wiring inside the disc spring mechanism is led to the terminal block of the detection device through the external connector 5, and the opening loop and the closing loop are respectively connected with the resistance display 4 through the opening-closing change-over switch 3. The motor energy storage loop is connected with a motor pressing contactor, a pressing delay protection relay and a miniature circuit breaker switch in the control panel 1 of the detection device, so that motor pressing operation can be performed. The contacts of the auxiliary switch in the auxiliary circuit are respectively connected in the independent circuit according to normally closed and normally open and are connected with the indicator lamp 2.

step one: as shown in the motor loop detection schematic diagram of fig. 3, the motor pressing loop of the disc spring mechanism performs pressing energy storage through a control panel of the detection device.
Normally open contacts KM1 (5, 6), KM1 (1, 2) and KM1 (3, 4) of the motor pressing contactor KM1 are connected with a motor M, a main contact of a pressure control switch PSY1 is connected with a motor pressing contactor coil KM1 (A1, A2) in series, and a main contact of the pressure control switch PSY1 is connected with a control coil of a pressing delay protection relay KT1 in series, and a normally open contact of the pressing delay protection relay KT1 is connected with the motor pressing contactor coil KM1 (A1, A2) in series.
The detection device controls the pressure control switch PSY1 to be closed, after the pressing delay protection relay KT1 delays, the motor presses the contactor coil KM1 (A1, A2) to obtain electricity so that normally open contacts KM1 (5, 6), KM1 (1, 2) and KM1 (3, 4) of the motor pressing contactor KM1 are closed, and the disc spring mechanism motor pressing loop stores energy.
