[0026] When the present invention is used, the DC voltmeter A1 or the AC voltmeter A2 can be switched through the energy storage current conversion switch SA1 to achieve switching between AC and DC. The socket CZ can be used as a power supply for a high-voltage switch characteristic tester. Limit switch SL1 represents a limit switch that stops after the rated pressure of the mechanism is fully stored, limit switch SL4 represents a travel switch that stops when the mechanism can close at the lowest oil pressure, and limit switch SL6 represents an energy storage stop travel switch when the mechanism can open at the lowest pressure.

The conversion signals of the normally open and normally closed nodes of the auxiliary switch QF1 are connected to the signals of the high-voltage switch characteristic tester for testing.

[0027] When the high-voltage switch is in the opening position, the contact between port No. 11 and port No. 12 of the auxiliary switch QF2 changes from normally open to normally closed, and the contact between port No. 113 and port No. 114, and the contact between port No. 123 and port No. 124 of the auxiliary switch QF2 changes from normally closed to normally open; when the high-voltage switch is in the closing position, the contact between port No. 11 and port No. 12 of the auxiliary switch QF2 changes from normally closed to normally open, and the contact between port No. 113 and port No. 114, and the contact between port No. 123 and port No. 124 of the auxiliary switch QF2 changes from normally open to normally closed, which can prevent the closing coil from being energized again in the closed state.

[0028] When the present invention is used, the main power switch Q1 is closed after the main power is connected, and then the high-voltage switch characteristic tester is turned on, and single-phase and three-phase are selected according to the product. When doing a single-phase test, the control cabinet plug-in X01 is connected to the single-phase switch. When doing a three-phase test, the control cabinet plug-in X01 needs to be connected to the A phase switch, the control cabinet plug-in X02 is connected to the B phase switch, and the control cabinet plug-in X03 is connected to the C phase switch, and then the break signal line is connected to the test position of the high-voltage switch characteristic tester. If it is a circuit breaker test, AC or DC is selected through the energy storage power conversion switch SA1, and then the energy storage working condition of the test is selected through the energy storage pressure conversion switch SA2. After pressing the energy storage output control button QA, the coil of the energy storage relay KM is energized, the thirteenth port and the fourteenth port of the energy storage relay KM are closed, and the forty-fourth port and the forty-three port are closed, the coils of the relay KMA, the relay KMB, and the relay KMC are energized, and the normally open contacts of the relay KMA, the relay KMB, and the relay KMC are closed, and the motor starts to store energy. After the energy storage is completed, the limit switch SL1, the limit switch SL4, and the limit switch SL6 are changed from normally closed to normally open to stop the motor energy storage, and the limit switch SL5, the limit switch SL7, and the limit switch SL8 are changed from normally open to normally closed, ready for closing or opening operation. The closing switch of the switch characteristic tester is closed to send a closing signal, and the port 16 of the transition terminal block D is positively charged, and then the port 1 of the control cabinet plug-in X01 is connected to the port 2 of the internal plug-in X1 of the mechanism. When the high-voltage switch is opened and the ports 11 and 12 of the auxiliary switch SF2 are normally closed, the closing circuit is turned on, the closing coil Y1 is energized, and a closing action is completed. After the closing is completed, the limit switch SL1, the limit switch SL4, and the limit switch SL6 are changed from normally open to normally closed to store energy for the motor again, and the limit switch SL5, the limit switch SL7, and the limit switch SL8 are changed from normally closed to normally open to prevent the opening and closing operations. After the energy storage is completed, the limit switch SL1, the limit switch SL4, and the limit switch SL6 are changed from normally closed to normally open to stop the motor energy storage, and the limit switch SL5, the limit switch SL7, and the limit switch SL8 are changed from normally open to normally closed, ready for the opening operation. The opening signal is issued by closing the opening switch of the switch characteristic tester, and the No. 19 port of the transition terminal block D is positively charged, and then the No. 3 port or No. 4 port of the control cabinet plug-in X01 is connected to the No. 4 port or No. 7 port of the internal plug-in X1 of the mechanism, and the opening circuit is turned on, and the opening coil Y2 or the opening coil Y3 is energized to complete a opening action. If a running-in test is required, the number of running-in and the interval time of opening and closing can be set in the high-voltage switch characteristic tester to perform automatic running-in. The switching of the opening coil Y2 and the opening coil Y3 can be realized through the opening coil conversion switch SA3.

[0029] If you want to do a switch characteristic test, you also need to install a speed sensor 3. The high-voltage switch characteristic tester is equipped with a sensor socket 1. The speed sensor 3 is a resistance type sensor. The brush of the resistance type sensor is connected to the operating device of the high-voltage switch. The speed of the contact movement is calculated by the change of the brush moving current, thereby measuring the closing speed and opening speed. The sensor socket 1 is three and can be connected to three speed sensors 3 through sensor cables 2 to measure the closing speed and opening speed of phase A, phase B, and phase C.

[0030] Inserting the control cabinet plug-in X04 into the high-voltage switch can test the small knife switch mechanism. The X04 plug-in directly uses the power supply of the high-voltage switch characteristic tester, and sends out opening and closing signals through the high-voltage characteristic switch tester, and feeds back the normally open and normally closed contact changes of the small knife switch mechanism to the break signal of the high-voltage switch characteristic tester for testing.
