[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0038] Figure 1 This is a schematic diagram of the structure of a counting circuit for testing the mechanical performance of an isolating switch provided in an embodiment of the present application. Figure 1 As shown, the counting circuit 100 for testing the mechanical performance of the disconnector includes: a power supply module 110, a counting module 120, an opening drive module 130 and a closing drive module 140;
[0039] The power module 110 is respectively connected to the counting module 120, the opening drive module 130, and the closing drive module 140; the opening drive module 130 is respectively connected to the counting module 120, the closing drive module 140, and the opening control module 210 on the isolating switch 200; and the closing drive module 140 is connected to the closing control module 220 on the isolating switch 200;
[0040] The power supply module 110 is used to provide power to the counting module 120, the opening drive module 130 and the closing drive module 140;
[0041] The counting module 120 is used to record the number of opening and closing times of the disconnector 200;
[0042] The opening drive module 130 is used to drive the opening control module 210 of the disconnecting switch 200 to operate, so that the disconnecting switch 200 performs an opening action;
[0043] The closing drive module 140 is used to drive the closing control module 220 of the disconnector 200 to operate, so that the disconnector 200 performs a closing action.
[0044] In this embodiment, the counting circuit 100 for testing the mechanical properties of the isolating switch is connected to the isolating switch 200, and can be used to control the opening and closing of the isolating switch 200, and record the number of times the isolating switch 200 is opened and closed, wherein one opening and closing cycle of the isolating switch 200 is counted as one time.
[0045] The power supply module 110 can provide an AC voltage of 220V to the counting module 120, the opening drive module 130 and the closing drive module 140, so that the counting module 120, the opening drive module 130 and the closing drive module 140 are activated.
[0046] The opening drive module 130 is connected to the opening control module 210 on the isolating switch 200, wherein the opening control module 210 is used to control the opening of the knife switch of the isolating switch 200. At this time, the opening drive module 130 is equivalent to the switch of the opening control module 210, and the opening of the knife switch is controlled by controlling the conduction and disconnection of the opening control module 210.
[0047] In addition, the opening drive module 130 is also connected to the closing drive module 140 to control the opening and closing of the knife switch.
[0048] The counting module 120 is connected to the opening drive module 130, and is used to record the action of the opening drive module 130 driving the isolating switch 200 to open. When the opening drive module 130 executes the action of driving the isolating switch 200 to open, it is recorded as one time. The closing drive module 140 is connected to the closing control module 220 on the isolating switch 200, wherein the closing control module 220 is used to control the closing of the knife switch of the isolating switch 200. At this time, the closing drive module 140 is equivalent to the switch of the closing control module 220, and the closing of the knife switch is controlled by controlling the conduction and disconnection of the closing control module 220.
[0049] Specifically, when the disconnector 200 is subjected to a mechanical life test, the power module 110, the counting module 120, the opening drive module 130, the closing drive module 140, and the opening control module 210 and the closing control module 220 on the disconnector 200 are connected according to the above-mentioned connection relationship.
[0050] The power module 110 is started, and the power module 110 provides power to the opening drive module 130 and the counting module 120. The opening drive module 130 turns on the opening control module 210 on the disconnector 200. At this time, the knife switch is opened, and at this time, the counting module 120 counts once. It should be noted that before starting the test, the knife switch needs to be in the closed state.
[0051] After the knife switch is opened, the power module 110 provides power to the closing drive module 140, and the closing drive module 140 turns on the closing control module 220 on the disconnector 200 to close the knife switch.
[0052] Then, after the knife switch is closed, the opening drive module 130 turns on the opening control module 210 on the isolating switch 200 again, so that the knife switch is opened, and the counting module 120 counts again, and this cycle is repeated to realize the control of closing and opening of the isolating switch 200 and the counting of the closing and opening times.
[0053] When the number of opening and closing times recorded by the counting module 120 reaches a preset value, the power module 110 is turned off and a mechanical life test is performed to test the durability and reliability of the mechanical structure of the disconnector 200 .
[0054] In this embodiment, by setting a power module 110, a counting module 120, an opening drive module 130 and a closing drive module 140, the power module 110 is connected to the counting module 120, the opening drive module 130 and the closing drive module 140 respectively, the opening drive module 130 is connected to the counting module 120, the closing drive module 140 and the opening control module 210 on the isolating switch 200 respectively, and the closing drive module 140 is connected to the closing control module 220 on the isolating switch 200. After the power module 110 is started, automatic control of the opening and closing of the isolating switch 200 and automatic statistics of the opening and closing times are realized, and because the opening and closing times are automatically counted, the opening and closing times can be accurately recorded, thereby improving the accuracy of the mechanical life test results, timely and accurately understanding the mechanical performance of the isolating switch 200 after a certain number of opening and closing times, and facilitating timely discovery of safety hazards of the isolating switch 200.
[0055] Optional, such as Figure 2 As shown, the counting circuit 100 for testing the mechanical performance of the disconnector further includes: an opening time control module 150 and a closing time control module 160;
[0056] The opening time control module 150 is respectively connected to the power module 110, the counting module 120, the closing drive module 140, and the closing time control module 160, and the closing time control module 160 is respectively connected to the power module 110 and the closing drive module 140;
[0057] The opening time control module 150 is used to control the opening time of the disconnector 200;
[0058] The closing time control module 160 is used to control the closing time of the disconnector 200 .
[0059] In this embodiment, the knife switch of the isolating switch 200 is frequently closed and opened, causing the transmission mechanism of the isolating switch 200 to be subjected to excessive pressure, which may cause its performance to degrade or fail. In addition, the closing of the knife switch may cause heat to be generated at the contact point between the contacts of the isolating switch 200 and the knife switch. Therefore, the closing and opening of the knife switch need to be interrupted.
[0060] Therefore, in this embodiment, an opening time control module 150 and a closing time control module 160 are provided. The opening time control module 150 starts timing when the disconnector 200 is opened, and when the opening time meets the preset opening time, the closing drive module 140 drives the disconnector 200 to close, so that the disconnector 200 is closed.
[0061] When the isolating switch 200 is closed, the closing time control module 160 starts timing. When the closing time meets the preset closing time, the closing drive module 140 is driven to execute the action of driving the opening drive module 130 to drive the isolating switch 200 to open, so that the isolating switch 200 is opened again.
[0062] In this embodiment, the opening time and the closing time are controlled respectively by the opening time control module 150 and the closing time control module 160, so that the opening time and the closing time can be adjusted according to actual needs, so that there is discontinuity between the closing and opening of the knife switch of the disconnector 200, thereby avoiding damage to the transmission mechanism caused by frequent closing and opening, and generating more heat at the contact part between the contact and the knife switch.
[0063] Optional, such as Figure 2 As shown, the counting circuit 100 for testing the mechanical performance of the disconnector further includes: an opening state indicator light HD and a closing state indicator light GD;
[0064] The opening state indicator light HD is respectively connected to the power module 110 and the opening auxiliary switch 230 of the isolating switch 200;
[0065] The closing status indicator light GD is connected to the power module 110 and the closing auxiliary switch 240 of the isolating switch 200 respectively.
[0066] In this embodiment, the opening auxiliary switch 230 of the isolating switch 200 is used to receive the opening signal, and the opening status indicator light HD is connected to the opening auxiliary switch 230. When the knife switch is opened, the opening auxiliary switch 230 transmits the opening signal to the counting circuit 100 for testing the mechanical properties of the isolating switch, so that the opening status indicator light HD is turned on, which is convenient for the staff to promptly understand that the knife switch is currently in the open state.
[0067] The closing auxiliary switch 240 of the isolating switch 200 is used to receive the closing signal, and the closing status indicator light GD is connected to the closing auxiliary switch 240. When the knife switch is closed, the closing auxiliary switch 240 transmits the closing signal to the counting circuit 100 for testing the mechanical properties of the isolating switch, so that the closing status indicator light GD is turned on, which is convenient for the staff to understand that the knife switch is currently in the closed state.
[0068] In this embodiment, by setting the opening status indicator HD and the closing status indicator GD, the opening status indicator HD and the closing status indicator GD are turned on or off according to the opening and closing status of the knife switch, so that the staff can understand the status of the disconnector 200 according to the opening status indicator HD and the closing status indicator GD.
[0069] Optional, such as Figure 3 and Figure 5 As shown, the counting module 120 includes: a timer, the coil JS-L of the timer and the first normally closed contact JS-1 of the timer are connected to the power module 110, and the second normally closed contact JS-2 of the timer is connected to the opening drive module 130.
[0070] Optional, such as Figure 3-Figure 5 As shown, the opening drive module 130 includes: a first relay;

[0072] Optional, such as Figure 3 and Figure 4 As shown, the closing drive module 140 includes: a second relay;
[0073] The coil KM2-L of the second relay and the normally closed contact KM2-1 of the second relay are both connected to the power supply module 110, the coil KM2-L of the second relay is also connected to the opening time control module 150 and the closing time control module 160 respectively, the normally closed contact KM2-1 of the second relay is also connected to the opening time control module 150, the first normally open contact KM2-2 of the second relay is connected to the closing time control module 160, and the second normally open contact KM2-3 of the second relay is connected to the closing control module 220.
[0074] Optional, such as Figure 3 As shown, the opening time control module 150 includes: a first time relay;
[0075] The coil T1-L of the first time relay is connected to the normally closed contact KM2-1 of the second relay and the power module 110 respectively, and the normally open contact T1-1 of the first time relay is connected to the power module 110, the closing time control module 160 and the coil KM2-L of the second relay respectively.
[0076] Optional, such as Figure 3 As shown, the closing time control module 160 includes: a second time relay;
[0077] The coil T2-L of the second time relay is connected to the normally closed contact T2-1 of the second time relay and the power module 110 respectively. The normally closed contact T2-1 of the second time relay is also connected to the normally open contact T1-1 of the first time relay and the first normally open contact KM2-2 of the second relay respectively.
[0078] For example, Figure 3-Figure 5 As shown, the power module 110 provides 220V AC power, and the power switch 1 controls the on and off of the 220V AC power.
[0079] The power switch 1 is connected to the circuit fuse 2, wherein the circuit is split into two circuit loops after the circuit fuse 2. In one circuit loop, the circuit fuse 2 is connected to the opening auxiliary switch 230 and the closing auxiliary switch 240 of the isolating switch 200, the opening auxiliary switch 230 is connected in parallel with the closing auxiliary switch 240, the opening auxiliary switch 230 is connected to the opening state indicator light HD, the closing auxiliary switch 240 is connected to the closing state indicator light GD, and the opening state indicator light HD and the closing state indicator light GD are connected to the 220V AC power.
[0080] In another circuit loop, the coil JS-L of the timer is connected to the 220V AC power through the circuit fuse 2; the normally closed contact KM2-1 of the second relay is connected to the 220V AC power through the circuit fuse 2, the first normally closed contact KM2-1 is connected to the coil T1-L of the first time relay and the coil KM1-L of the first relay, and the coil T1-L of the first time relay is connected in parallel with the coil KM1-L of the first relay;
[0081] The first normally open contact KM2-2 of the second relay and the normally open contact T1-1 of the first time relay are connected in parallel and connected between the circuit fuse 2 and the normally closed contact T2-1 of the second time relay. The coil T2-L of the second time relay is connected in parallel with the coil KM2-L of the second relay and connected to the normally closed contact T2-1 of the second time relay.
[0082] One end of the first normally closed contact JS-1 of the timer is connected to a 220V AC power supply, and the other end is connected to the coil T1-L of the first time relay, the coil KM1-L of the first relay, the coil T2-L of the second time relay, and the coil KM2-L of the second relay.
[0083] And, if Figure 4 As shown, the normally open contact KM1 - 1 of the first relay is connected to the opening control module 210 , and the second normally open contact KM2 - 3 of the second relay is connected to the closing control module 220 .
[0084] like Figure 5 As shown, the normally closed contact KM1-2 of the first relay is connected to the second normally closed contact JS-2 of the timer, and is used to control the on and off of the second normally closed contact JS-2 of the timer.
[0085] according to Figure 3-Figure 5 The circuit shown here illustrates the working principle of the counting circuit 100 for testing the mechanical performance of the isolating switch 200:
[0086] When conducting a mechanical life test, close the power switch 1. At this time, the coil JS-L of the timer is energized, and the timer JS starts running to record the number of openings.
[0087] The current passes through the normally closed contact KM2-1 of the second relay to energize the coil T1-L of the first time relay and the coil KM1-L of the first relay. The coil KM1-L of the first relay is energized so that Figure 4 The normally open contact KM1-1 of the first relay is closed, so that the opening control module 210 is connected to the power supply DC, and the isolating switch 200 is opened. When the isolating switch 200 is opened, the opening auxiliary switch 230 is turned on, so that the opening state indicator HD is turned on.
[0088] It should be noted that the closing auxiliary switch 240 is in a normally closed state, so the closing status indicator GD is in an on state. However, when the isolating switch 200 is opened so that the opening auxiliary switch 230 is turned on, the opening status indicator HD is turned on and the closing status indicator GD is automatically turned off.
[0089] At this time, the coil KM1-L of the first relay is energized, so that Figure 5 The normally closed contact KM1-2 of the first relay in is disconnected, thereby disconnecting the second normally closed contact JS-2 of the timer, indicating that the disconnector 200 is opened and the timer counts once.
[0090] At the same time, the first time relay T1 starts timing. When the opening time reaches the preset opening time, the normally open contact T1-1 of the first time relay is closed, so that the current passes through the normally open contact T1-1 of the first time relay and the normally closed contact T2-1 of the second time relay, and enters the coil T2-L of the second time relay and the coil KM2-L of the second relay.
[0091] At this time, since the coil KM2-L of the second relay is energized, the normally closed contact KM2-1 of the second relay is disconnected, and the first normally open contact KM2-2 of the second relay and the second normally open contact KM2-3 of the second relay are closed. The second normally open contact KM2-3 of the second relay is closed, so that the closing control module 220 and the power supply DC are connected, so that the isolation switch 200 is closed. Among them, when the isolation switch 200 is closed, the opening auxiliary switch 230 is disconnected (that is, there is no opening signal), the opening status indicator HD is turned off, and the closing auxiliary switch 240 turns on the closing status indicator GD.
[0092] At this time, the second time relay T2 starts timing, and when the closing time reaches the preset closing time, the normally closed contact T2-1 of the second time relay is disconnected. The normally closed contact T2-1 of the second time relay is disconnected, causing the coil KM2-L of the second relay to lose power, causing the normally closed contact KM2-1 of the second relay to close, thereby performing the next cycle of opening and closing.
[0093] Among them, when the number of opening and closing recorded by the counter reaches a preset value, the first normally closed contact JS-1 of the timer is disconnected, so that the coil T1-L of the first time relay, the coil KM1-L of the first relay, the coil T2-L of the second time relay, and the coil KM2-L of the second relay are all de-energized, causing the isolating switch 200 to stop opening and closing actions.
[0094] Optionally, the counting module 120 may also be connected to the closing drive module 140 to record the action of the closing drive module 140 driving the isolating switch 200 to close. When the closing drive module 140 executes the action of driving the isolating switch 200 to close, it is recorded as one time.
[0095] Specifically, the second relay is also provided with a second normally closed contact KM2-4, wherein the second normally closed contact KM2-4 of the second relay is connected to the second normally closed contact JS-2 of the timer, and is used to control the conduction and disconnection of the second normally closed contact JS-2 of the timer. When the coil KM2-L of the second relay is energized, the second normally closed contact KM2-4 of the second relay is disconnected, thereby disconnecting the second normally closed contact JS-2 of the timer, indicating that the isolating switch 200 is closed and the timer counts once.
[0096] On the basis of the above embodiments, the present application further provides a counting device for testing the mechanical performance of an isolating switch, which includes: a box and a counting circuit 100 for testing the mechanical performance of an isolating switch as described in any of the above embodiments.
[0097] Among them, the counting circuit 100 for testing the mechanical performance of the isolating switch is integrated inside the box. When it needs to be connected to the isolating switch 200, for example, the opening status indicator HD is connected to the opening auxiliary switch 230 of the isolating switch 200, and the closing status indicator GD is connected to the closing auxiliary switch 240 of the isolating switch 200, and can be connected to the isolating switch 200 through a terminal block.
[0098] Optionally, the connector of the terminal block adopts an aviation connector to improve the reliability and stability of the connector.
[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
