Description

Technical Field

[0001] This utility model relates to the field of power secondary equipment technology, and in particular to a relay protection device that can be quickly located. Background Technology

[0002] Relay protection is an important component of power systems. Relay protectors are often used to provide safety protection for power equipment. They are mainly used to disconnect the faulty part of the circuit in time when a fault or abnormal phenomenon occurs in the power system, so as to protect the safe operation of the power system and protect the power equipment from damage caused by overcurrent, overvoltage and other factors.

[0003] Relay protectors can be installed inside control cabinets or on panels. For large cabinets, a rail mounting method can be used. For rail mounting, the relay protector needs to be placed on the rail and then fixed with screws. However, when fixing, it is necessary to ensure that the position of the relay protector is correct. One hand needs to hold the relay protector and the other hand needs to fix it with screws, which makes the installation and positioning of the relay protector inconvenient.

[0004] Furthermore, since installing and disassembling relays requires removing screws, the operation is very troublesome. When it is necessary to replace relays of different models and sizes, new holes need to be drilled to fix the relays because the dimensions are different from the previous ones, which is labor-intensive and time-consuming.

[0005] Therefore, this application provides a relay protection device with rapid location capability to meet the requirements. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a relay protection device that can be quickly located.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A fast-positioning relay protector includes: a guide rail, a relay protector housing, a threaded sleeve, an adjusting screw, a rotary handle, a telescopic spring, a patch, a plug rod, and a limiting block. The relay protector housing is mounted on the outer end of the guide rail. A placement groove is provided at the lower end of the interior of the relay protector housing. An adjustment port is provided at the lower end of the side of the relay protector housing. A retaining groove is provided at the middle of the bottom of the relay protector housing. A threaded sleeve is installed inside the placement groove of the relay protector housing. An adjusting screw is installed at the adjustment port of the relay protector housing. A rotary handle is installed at the outer end of the adjusting screw. A telescopic spring is installed on the side of the threaded sleeve in the placement groove. A patch is installed at the end of the telescopic spring. A plug rod is installed on the side of the telescopic spring in the placement groove. A limiting block is installed at one end of the plug rod.

[0009] Preferably, there are two sets of placement slots and adjustment ports, with the two sets of placement slots and adjustment ports located at the lower ends of the left and right sides of the relay protector housing, respectively.

[0010] Preferably, one end of the placement groove is connected to the adjustment port, and the other end of the placement groove extends to the side of the card slot and is connected to the card slot.

[0011] Preferably, the threaded sleeve is installed at the adjustment port, the length of the adjustment screw is greater than the length of the threaded sleeve, and the adjustment screw and the threaded sleeve are threadedly connected.

[0012] Preferably, patches are installed at both ends of the telescopic spring, and the adjusting screw extends through the threaded sleeve to the side of the telescopic spring and abuts against the patch.

[0013] Preferably, the limiting block abuts against the patch at the other end of the telescopic spring, and the insertion rod extends laterally through the placement groove to the inside of the slot, abutting against the side of the guide rail.

[0014] Preferably, the insertion rod is elongated, and the extended end face of the insertion rod is trapezoidal, with the upper end face of the insertion rod adhering to the lower end surface of the outer edge of the guide rail.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, two sets of placement slots and adjustment ports are set at the lower ends of the left and right sides of the relay protector housing. By turning the handle at the adjustment ports on the left and right sides, the adjustment screw can rotate inside the threaded sleeve, thereby adjusting the length extended into the placement slot. The adjustment screw can abut against the patch, and the telescopic spring is pressured by the adjustment screw, thereby pushing the insertion rod at the other end to move. The insertion rod extends outward and abuts against the guide rail, allowing the relay protector to be installed on the guide rail. This makes the installation and positioning of the relay protector more convenient; it can be directly snapped onto the guide rail and then adjusted.

[0017] In the above solution, by setting the length of the adjusting screw to be greater than the length of the threaded sleeve, the adjusting screw can rotate inside the threaded sleeve, thereby adjusting the length extended into the placement groove. By controlling the length of the adjusting screw extending into the placement groove, the length of the insert rod extending into the slot can be controlled, as can the compression degree of the telescopic spring and the length of the insert rod extending outward. This allows for installation according to guide rails of different sizes. Compared to traditional drilling and screw installation, installation is not only more convenient but also faster.
