Description

Technical Field

[0001] This utility model belongs to the field of high-voltage fuse applications. It is used to simulate the energy released by the impactor when the high-voltage fuse blows. It is used to verify whether the energy can drive the start switch of the drive unit of the combination switch, and can also verify whether the drive unit of the high-voltage combination switch can work normally to disconnect the line under a given impact energy. Background Technology

[0002] High-voltage fuses are widely used in high-voltage power transmission and distribution systems, primarily for short-circuit protection, and are one of the important protective components of high-voltage transformers. High-voltage fuses are simple in structure, small in size, light in weight, and inexpensive, and possess high breaking capacity and good current-limiting characteristics. When used in combination with high-voltage composite switches, they offer excellent technical and economic benefits.

[0003] When a high-voltage fuse blows, the striker pops out. The energy released by the striker's impact drives the linkage switch of the high-voltage composite switch drive unit, disconnecting the high-voltage power supply to the transformer to protect the transformer and other related components. However, if the energy released by the striker is insufficient to drive the high-voltage composite switch drive unit to disconnect the high-voltage power supply to the transformer, or if a fault in the composite switch drive unit prevents the switch from disconnecting, the high-voltage fuse will continue to flow with a small current after blowing, even if the high-voltage power supply is not disconnected. This can lead to abnormal and continuous heating of the fuse, which, if accumulated, may damage the fuse bushing, contaminate the transformer oil, or cause a fire, resulting in greater economic losses. Utility Model Content

[0004] The purpose of this invention is to provide a remote-controlled, rechargeable, electric simulated impactor to solve the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A remote-controlled rechargeable electric simulated impactor includes a left contact, a right contact, a cylindrical mechanism, a power switch, a charging port, and a battery level indicator. The left contact is threaded to the left side of the cylindrical mechanism, and the right contact is threaded to the right side of the cylindrical mechanism. The power switch is installed on the left side of the front of the cylindrical mechanism, the charging port is located to the right of the power switch, and the battery level indicator is installed to the right of the charging port.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3 As shown, a remote-controlled rechargeable electric simulated impactor includes a left contact 1, a right contact 2, a cylindrical body mechanism 3, a power switch 4, a charging port 5, and a battery level indicator 6. The left contact 1 is threaded to the left side of the cylindrical body mechanism 3, and the right contact 2 is threaded to the right side of the cylindrical body mechanism 3. The power switch 4 is installed on the left side of the front of the cylindrical body mechanism 3, the charging port 5 is located on the right side of the power switch 4, and the battery level indicator 6 is installed on the right side of the charging port 5.

[0020] The cylindrical mechanism 3 includes a bracket 7, a pad 8, a push-pull electromagnet 9, a first connecting rod 10, a second connecting rod 11, a cap removal hook support 12, a cap removal hook 13, a cap removal cap 14, a spring rod 15, a spring tube 16, a locking nut 17, a spring washer 18, a spring 19, a firing pin 20, a battery pack 21, and a remote control signal receiving control board 22. The bracket 7, the pad 8, and the spring tube 16 are welded together. The cap removal hook support 12 is connected to the welded body using screws. The push-pull electromagnet 9, the first connecting rod 10, the second connecting rod 11, and the cap removal hook support 12 are screwed to the bracket 7. Figure 2 The connection shown is such that the spring rod 15 is as follows: Figure 7 As shown, the spring-loaded round pad 18 and spring 19 are inserted into the reed tube 16. The left end of the spring rod 15 is threaded to the release cap 14, and the right end is threaded to the firing pin 20. The external thread end of the reed tube 16 is pre-screwed with a locking nut 17. The firing pin 20 passes through the right contact 2, and the right contact 2 is threaded to the reed tube 16. The firing pin 20 extends from the firing pin hole of the right contact 2. Due to the obstruction of the firing pin limiting step, the firing pin 20 cannot completely pass through the right contact 2. The battery pack 21 and the remote control signal receiving control board 22 are pressed... Figure 2 The battery pack 21 is installed and fixed in the indicated position. The control mode of the battery pack 21 is preset to jog control mode, meaning that the normally open contact NO closes when a signal is received, and the normally open contact NO opens when a signal is received. Figure 8 The wiring diagram shows the connection between the battery pack 21, the push-pull electromagnet 9, and the remote control signal receiving control board 22.

[0021] The working principle of this utility model: This utility model, in accordance with... Figure 1 , 2 4. After installation, press the striker (20), and the compression spring (19) will drive the hook cap (14) to move backward through the spring rod (15). The conical surface of the hook cap (14) will contact the inclined surface of the hook cap (13), so that the hook cap (13) will be subjected to a radial force around the fixed axis, open and pass over the step surface of the hook cap (14), and then close and clamp the hook cap (14) under the action of the push-pull electromagnet (9) reset spring. The size of the striker (20) pressing into the right contact and protruding from the end face of the right contact (2) should be less than 1.5mm. If this size is not met, it can be adjusted by adjusting the thread engagement depth of the right contact (2) and the reed tube (16), or by adjusting the thread connection length of the hook cap (14), the spring rod (15), and the striker (20). When the striker (20) is assembled to meet the requirements, tighten the locking nut (17) so that the right contact (2) cannot be easily loosened relative to the reed tube (16). When the impact energy of the firing pin after the release of the hook cap is not sufficient, the impact energy released by the spring can be adjusted by adjusting the compression ratio of the spring (19) by adjusting the thickness of the spring round pad (18).

[0022] When the push-pull electromagnet (9) is energized, the electromagnet core shaft retracts, and the cap removal hook (13) rotates around the fixed axis by the connecting rod 1 (10) and connecting rod 2 (11). Under the action of the spring (19) reset force, the cap removal cap (14) is released, and the pressing pin (20) is pushed out by the spring rod (15). After the power is cut off, the push-pull electromagnet (9) returns to the initial position under the action of the reset spring, and the cap removal hook (13) returns to the closed angle through the linkage of connecting rod 1 (10) and connecting rod 2 (11).

[0023] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
