Description

Technical Field

[0001] The present disclosure relates to the technical field of switch cabinet electricity testing, and in particular to a switch cabinet electricity testing auxiliary device and an electricity testing method. Background Art

[0002] Switchgear is a common power distribution device in power supply systems such as hydropower stations. To ensure the safe and long-term stable operation of the equipment, operators need to regularly perform maintenance work on the switchgear according to the maintenance plan. Before the maintenance work, the equipment to be repaired needs to be grounded. In addition, the power safety regulations require that before the grounding wire is hung on the power equipment, the corresponding parts of the equipment need to be tested with a qualified tester of the corresponding voltage level. Only after confirming that there is no voltage can the grounding work be carried out.

[0003] Since the switch cabinet is a fully enclosed structure, it is not possible to use the method of contacting the conductor through a tester. At this stage, only a test cart and indirect test methods can be used for testing.

[0030] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present disclosure proposes a switch cabinet electrical testing auxiliary device, including: a first insulating support 2, an insulating support 1 and a second insulating support 3, the first insulating support 2 is arranged at the bottom of the circuit breaker chamber of the switch cabinet, the middle part of the insulating support 1 is arranged on the first insulating support 2, and the first end of the insulating support 1 is arranged at the bottom of the lifting connecting rod of the valve 6 in the circuit breaker chamber, the second end of the insulating support 1 is arranged at the opening of the circuit breaker chamber, the insulating support 1 is used to lift the lifting connecting rod upward at the first end to open the valve 6 when downward pressure is applied to the second end, and the second insulating support 3 is used to be stuck between the bottom of the circuit breaker chamber and the first end of the insulating support 1 when the first end of the insulating support 1 is lifted upward.

[0032] It can be understood that, since the first insulating support 2 is arranged at the bottom of the circuit breaker chamber and the middle part of the insulating support 1 is arranged on the first insulating support 2, the insulating support 1 can form a lever structure with the first insulating support 2 as the fulcrum, so that when the second end of the insulating support 1 is applied with downward pressure, the first end of the insulating support 1 can be lifted upward, and since the first end of the insulating support 1 is arranged at the bottom of the lifting connecting rod of the valve 6, the lifting of the first end of the insulating support 1 can drive the lifting connecting rod to rise, thereby realizing the opening of the valve 6. At the same time, when the first end of the insulating support 1 is lifted upward, the second insulating support 3 is clamped between the bottom of the circuit breaker chamber and the first end of the insulating support 1, so that the first end of the insulating support 1 can maintain a lifted state under the support of the second insulating support 3, thereby enabling the valve 6 to be continuously opened.

[0033] Among them, the arrangement of auxiliary devices allows the valve 6 to be continuously opened, so that the wiring contacts 9 of the circuit breaker chamber can always be in an exposed state, which makes it easier to use electric testers and other electric testing equipment to directly test the electricity. Therefore, compared with the indirect testing method of using a bulky electric testing cart, the direct testing method of using electric testers and other electric testing equipment greatly reduces the operation time and improves the operation efficiency. At the same time, it has higher reliability and avoids the direct operation of the valve 6 by the operator, effectively reducing the risk of electric shock and improving the operation safety.

[0034] It should be noted that the switch cabinet can be a 10kV switch cabinet, which has multiple electrical equipment, such as circuit breakers. The circuit breakers are arranged in the circuit breaker room of the switch cabinet in the form of a trolley. The circuit breaker room has wiring contacts 9 for circuit connection (such as bus three-phase contacts) and valves 6 for shielding and protecting the wiring contacts 9. The valve 6 is slidably arranged and can be lifted and lowered under the drive of the lifting connecting rod. When the valve 6 is lifted, the valve 6 is away from the wiring contacts 9 and is in an open state. When the valve 6 is lowered, the valve 6 shields the wiring contacts 9 and is in a closed state.

[0035] Furthermore, when the circuit breaker trolley is moved into the circuit breaker chamber, the circuit breaker trolley uses the push-up mechanism thereon to touch the lifting rod of the valve 6, so that the valve 6 opens and exposes the wiring contacts 9, and then the wiring contacts 9 are used to achieve circuit connection. When the circuit breaker trolley is moved out of the circuit breaker chamber, the push-up mechanism of the circuit breaker trolley is away from the lifting rod of the valve 6, so that the valve 6 closes and blocks the wiring contacts 9, so as to protect the wiring contacts 9.

[0036] The auxiliary device of this embodiment can realize the safe opening of the valve 6, so that the wiring contacts 9 can be continuously exposed when the circuit breaker trolley is moved out of the circuit breaker chamber, thereby facilitating direct electrical testing of electrical testing equipment such as a tester using the exposed wiring contacts 9.

[0041] It can be understood that, due to the V-shaped structure of the first V-shaped frame 21 and the concave surface of the first V-shaped frame 21 facing the bottom of the circuit breaker chamber, the middle part of the insulating bracket 1 is arranged on the protruding surface of the first V-shaped frame 21, so that the first insulating support 2 can stably support the insulating bracket 1 while also allowing the insulating bracket 1 to have a larger rotation space, thereby making the driving operation of the insulating bracket 1 on the lifting connecting rod more stable and convenient.

[0042] It should be noted that the first V-shaped frame 21 is a V-shaped structure, and the first V-shaped frame 21 has a convex surface with a smaller width and a concave surface with a larger width. The concave surface of the first V-shaped frame 21 is supported on the bottom of the circuit breaker chamber, so that it has higher stability. The convex surface of the first V-shaped frame 21 supports the middle part of the insulating bracket 1, so that the rotation resistance of the insulating bracket 1 is smaller and the activity space is larger. The specific type of the first V-shaped frame 21 can be set according to actual needs and is not limited to this.

[0043] like Figure 2 As shown, in some embodiments, the first insulating support 2 further includes: a first limiting frame 22, the first limiting frame 22 is arranged at the first end of the first V-shaped frame 21, and the first limiting frame 22 is used to limit the first side of the insulating support 1;

[0050] It can be understood that, due to the V-shaped structure of the second V-shaped frame 31 and the concave surface of the second V-shaped frame 31 facing the bottom of the circuit breaker chamber, the middle part of the insulating bracket 1 is arranged on the protruding surface of the second V-shaped frame 31, so that the second insulating support 3 can stably support the first end of the insulating bracket 1, thereby ensuring the stable and continuous opening of the valve 6.

[0051] It should be noted that the second V-shaped frame 31 is a V-shaped structure, and the second V-shaped frame 31 has a convex surface with a smaller width and a concave surface with a larger width. The concave surface of the second V-shaped frame 31 is supported on the bottom of the circuit breaker chamber, so that it has higher stability.

[0054] It should be noted that the third limiting frame 32 is used to limit the first side of the insulating bracket 1, and the specific type of the third limiting frame 32 can be set according to actual needs and is not limited to this.

[0055] like Figure 2 As shown, in some embodiments, the second insulating support 3 further includes: a fourth limiting frame 33, which is arranged at the second end of the second V-shaped frame 31, and the fourth limiting frame 33 is used to limit the second side of the insulating support 1.

[0056] It can be understood that since the fourth limit frame 33 is arranged at the second end of the second V-shaped frame 31, the fourth limit frame 33 can limit the second side of the insulating bracket 1, thereby preventing the insulating bracket 1 from deviating to the second side when the lifting link is continuously lifted, thereby ensuring the stable and continuous opening of the valve 6.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the auxiliary device also includes: a first lifting seat 4, which is arranged on the first side of the first end of the insulating bracket 1, and the first lifting seat 4 is provided with a first card slot 41, and the first card slot 41 is clamped at the bottom of the first lifting rod 7 of the valve 6.

[0059] It can be understood that since the first lifting seat 4 is provided with a first card slot 41, and the first card slot 41 is clamped at the bottom of the first lifting link 7 of the valve 6, the first side of the first end of the insulating bracket 1 can be stably connected to the first lifting link 7 by utilizing the clamping of the first card slot 41, thereby realizing the stable driving of the first lifting link 7 by the insulating bracket 1, and further ensuring the stable opening of the valve 6.

[0062] It can be understood that since the second lifting seat 5 is provided with a second card slot 51, and the second card slot 51 is clamped at the bottom of the second lifting link 8 of the valve 6, the second side of the first end of the insulating bracket 1 can be stably connected to the second lifting link 8 by utilizing the clamping of the second card slot 51, thereby realizing the stable driving of the second lifting link 8 by the insulating bracket 1, and further ensuring the stable opening of the valve 6.

[0063] It should be noted that the second lifting seat 5 is used to achieve a stable connection between the second side of the first end of the insulating bracket 1 and the bottom of the second lifting rod 8.

[0069] like Figure 4 As shown, the embodiment of the present disclosure further proposes an electric power testing method, which is based on the switch cabinet electric power testing auxiliary device as in the embodiment of the present disclosure, and the electric power testing method includes:

[0070] S1: Cut off the power supply of the switch cabinet and move the circuit breaker in the switch cabinet out of the circuit breaker room;

[0071] S2: Arrange the first insulating support 2 and the insulating bracket 1 in the auxiliary device in sequence in the circuit breaker chamber;

[0072] S3: applying downward pressure on the second end of the insulating support 1 so that the first end of the insulating support 1 opens the shutter 6 of the circuit breaker chamber, thereby exposing the wiring contacts 9 of the circuit breaker chamber;

[0073] S4: clamping the second insulating support 3 in the auxiliary device between the bottom of the circuit breaker chamber and the first end of the insulating support 1 to keep the valve 6 in an open state;

[0074] S5: Test the wiring contact 9 for electricity. When it is determined that there is no voltage on the wiring contact 9, ground the wiring contact 9.

[0075] It can be understood that, since the first insulating support 2 is arranged at the bottom of the circuit breaker chamber and the middle part of the insulating support 1 is arranged on the first insulating support 2, the insulating support 1 can form a lever structure with the first insulating support 2 as the fulcrum, so that when the second end of the insulating support 1 is applied with downward pressure, the first end of the insulating support 1 can be lifted upward, and since the first end of the insulating support 1 is arranged at the bottom of the lifting connecting rod of the valve 6, the lifting of the first end of the insulating support 1 can drive the lifting connecting rod to rise, thereby realizing the opening of the valve 6. At the same time, when the first end of the insulating support 1 is lifted upward, the second insulating support 3 is clamped between the bottom of the circuit breaker chamber and the first end of the insulating support 1, so that the first end of the insulating support 1 can maintain a lifted state under the support of the second insulating support 3, thereby enabling the valve 6 to be continuously opened.

[0076] Among them, the arrangement of auxiliary devices allows the valve 6 to be continuously opened, so that the wiring contacts 9 of the circuit breaker chamber can always be in an exposed state, which makes it easier to use electric testers and other electric testing equipment to directly test the electricity. Therefore, compared with the indirect testing method of using a bulky electric testing cart, the direct testing method of using electric testers and other electric testing equipment greatly reduces the operation time and improves the operation efficiency. At the same time, it has higher reliability and avoids the direct operation of the valve 6 by the operator, effectively reducing the risk of electric shock and improving the operation safety.

[0077] In some embodiments, the electricity testing method further includes: testing the wiring contact 9 with an electric tester, and when it is determined that the wiring contact 9 has no voltage, moving a grounding trolley into the circuit breaker chamber to ground the wiring contact 9 with the grounding trolley.
