Description

Technical Field

[0001] The invention relates to the field of relay protection, and in particular to a relay protector capable of automatically cutting off power. Background Art

[0002] Relay protection is a comprehensive relay protection device based on microprocessor design, integrating inverse time and definite time relay protection. Relay protection is often used to provide safety protection for power equipment, such as short circuit and ground failure protection of transformers, motors, generators and power distribution system transmission lines.

[0003] Regarding relay protectors, a "protective relay protector" is disclosed in Chinese patent documents, with the publication number CN218124299U, which includes: a housing and a conductor, the top and bottom of the housing are both equipped with a wiring shell, and the interior of the wiring shell is equipped with three insulating frames at equal intervals. This solution solves the problem that when the existing device is in use, the contact surface of the fixed conductor on the relay protector is limited, and it is very easy to fall off and have poor contact, and its structure is not optimized enough and the design is not reasonable enough.

[0004] At present, the relay protector is installed by covering the relay protector with a protective cover through a plurality of bolts, and then fixing the protective cover and the wall through a plurality of bolts. However, this method is not convenient for maintenance. When maintenance is required, the installation and disassembly process is time-consuming and labor-intensive, which results in the problem of low convenience of the device. In addition, the relay protector does not effectively arrange and fix the conductors connected to the relay protector during daily use. After long-term use, the wire connector will become loose at the connection with the relay protector, which results in the problem of low stability of the relay protector during use. Summary of the invention

[0005] The present invention mainly solves the problem of low stability of the prior art relay protector during use; provides a relay protector that can automatically cut off the power, can conveniently disassemble and install the relay protector, and can bundle and limit the wires connected to the relay protector.

[0006] The above technical problems of the present invention are mainly solved by the following technical solutions: A relay protector capable of automatically cutting off power, comprising a mounting plate and a relay protection cover; and A clamping mechanism, comprising a fixed base and a clamping frame connected to each other; The fixing seat fixes the clamping mechanism on the mounting plate; The clamping frame clamps and fixes the relay protection cover on the mounting plate; The wire harness mechanism comprises a plurality of wire harness grooves for harnessing the wires extending from the relay protection cover.

[0007] Fixing the relay protection cover by the clamping mechanism effectively solves the problem that the installation and disassembly process is time-consuming and labor-intensive when the device needs to be maintained during actual use, which in turn causes the problem of low convenience of the device. During the entire operation, the protective cover outside the relay protector can be effectively and conveniently fixed and clamped, so that the relay protector in the device can be protected, and it can also be disassembled, which is convenient for subsequent staff to maintain and inspect the device, thereby improving the convenience of the device.

[0008] The wire bundling mechanism is used to bundle the wires, which effectively solves the problem that the wire joints will become loose at the connection with the relay protector after long-term use of the device, thereby causing the relay protector to have low stability during use. The wires connected to the device can be effectively bundled during the entire operation process, and the length of the wire bundling mechanism can be adjusted according to the different wires connected to the device, so that the wires connected to the device are arranged neatly, which is convenient for later maintenance and inspection, thereby improving the practicability of the device.

[0009] Preferably, the bottom of both sides of the relay protection cover is provided with connecting plates extending from the mounting plate, and the connecting plates are used to fix the clamping mechanism.

[0010] Preferably, the fixed base comprises a fixed plate, a connecting nut and a connecting frame; extension blocks extend from both sides of the fixed plate; the connecting nut passes through the threaded holes on the extension blocks and is fixedly connected to the mounting plate; the connecting frame is fixedly arranged on the fixed plate, and the connecting frame is hinged to one end of the clamping frame. The clamping frame is movably connected to the connecting frame, and is used to movably clamp or release the relay protection cover, which is convenient to use.

[0011] Preferably, the clamping frame comprises: The pushing part comprises a rotating frame and a pushing handle arranged at one end of the rotating frame; The transmission arm transmits the thrust of the pushing part to the clamping part, and controls the clamping state of the clamping part and the relay protection cover; The clamping part clamps and fixes the relay protection cover on the mounting plate.

[0012] Preferably, the transmission arm comprises: A rotating arm, one end of which is hinged to the fixing seat through a first connecting shaft; and the other end is connected to the clamping part; The connecting rod is respectively connected with the transmission arm and the rotating frame through a connecting shaft.

[0013] The push handle is moved to drive the rotating frame to move in the direction of the relay protection cover forward, and while the rotating frame is moving, the second connecting shaft rotatably connected to the inner wall of the rotating frame will drag the connecting rod connected to its outer surface and the rotating arm connected to the end of the connecting rod downward, thereby driving the internal adjusting rod and the extrusion clamping plate connected to the end of the adjusting rod to clamp downward through the descending of the rotating arm, thereby clamping the connecting plate to fix the relay protection cover on the top of the mounting plate, and by repeating the above operation in reverse, the fixation of the relay protection cover can be released, effectively solving the problem that the installation and disassembly process is time-consuming and labor-intensive when the device needs to be maintained during actual use, thereby causing the problem of low convenience of the device.

[0014] Preferably, a sliding groove is provided on the rotating arm; the clamping portion comprises an extrusion clamping plate, and the extrusion clamping plate is slidably connected to the rotating arm via a sliding plate.

[0015] Preferably, the wiring harness mechanism comprises: The fixing frame is fixed on the mounting plate and is respectively arranged on both sides of the relay protection cover; A telescopic rod, comprising a telescopic portion and a connecting rod portion; The telescopic part is provided with a plurality of jacks, and the telescopic parts at both ends are respectively sleeved in the fixed frames; The connecting rod part is provided with a plurality of wire-binding grooves for bundling the wires; Adjust the latch, insert it from the side of the fixed frame, and align it with the socket on the telescopic part of the telescopic rod.

[0017] Preferably, the connecting rod portion of the telescopic rod is respectively connected with a clamping block at a position corresponding to the wire harness groove, and a clamping block is arranged at a position corresponding to the wire harness groove, and a groove for adapting the wire is arranged on the clamping block.

[0018] When the relay protection cover outside the relay protector is installed and fixed, the adjusting pin is first pulled from the outside, and the telescopic rod is pulled out of the inside of the fixed frame. After the telescopic rod reaches a certain distance, the contact force on the adjusting pin is applied, so that the adjusting pin is driven to reset under the action of the elastic force of the telescopic spring, thereby completing the connection of the adjusting pin to the telescopic rod, thereby completing the limit fixation of the telescopic rod. Then, the extending part of the relay protection cover is placed in the groove at the top of the telescopic rod, and the clamping block is clamped in the inside of the telescopic rod, and the clamping block clamps the wire. This effectively solves the problem that the wire joint of the device will become loose at the connection with the relay protector after long-term use, thereby causing the problem of low stability of the relay protector during use.

[0019] The beneficial effects of the present invention are: 1. Fixing the relay protection cover by the clamping mechanism effectively solves the problem that the installation and removal process is time-consuming and labor-intensive when the device needs to be maintained during actual use, which in turn causes the device to be less convenient. During the entire operation, the protective cover outside the relay protector can be effectively and conveniently fixed and clamped, so that the relay protector in the device can be protected, and it can also be disassembled, which is convenient for subsequent staff to maintain and inspect the device, thereby improving the convenience of the device.

[0020] 2. The wires are bundled by the wire bundling mechanism, which effectively solves the problem that the wire joints and the connection with the relay protector become loose after long-term use, thereby causing the relay protector to have low stability during use. The wires connected to the device can be effectively bundled during the entire operation process, and the length of the wire bundling mechanism can be adjusted according to the different wires connected to the device, so that the wires connected to the device are neatly arranged, which is convenient for later maintenance and inspection, thereby improving the practicality of the device.
