Technical Field
[0001] The utility model relates to the technical field of ring main unit cabinets, in particular to a detachable secondary cabinet for a ring main unit cabinet. Background Art
[0002] A ring main unit cabinet (also known as a ring main unit) is a key device in a ring-shaped distribution network and is mainly used in a distribution system where the power supply trunk forms a closed loop. It distributes power outward through high-voltage switchgear, improving the reliability and flexibility of power supply. A variety of electrical devices are integrated inside the ring main unit cabinet, including load switches, fuses, current transformers, etc., to achieve the distribution, control, and protection of electric energy. The secondary cabinet, as a component of the ring main unit cabinet, mainly refers to the cabinet or module inside it for the secondary system (i.e., auxiliary systems such as protection, control, and measurement). These cabinets or modules are designed to be detachable. Specifically, this design allows the replacement, repair, or upgrade of the secondary system without affecting the normal operation of the main structure of the ring main unit cabinet and the primary system (i.e., the system directly involved in power transmission and distribution).
[0003] Currently, the secondary cabinet body in the prior art is an integral structure with the ring main unit cabinet body. When it is necessary to lay secondary wires inside the secondary cabinet body, since the secondary cabinet body is fixed on the top of the ring main unit cabinet body and is at a relatively high position, workers need to raise their hands and lift their arms to perform the wiring operation. In this wiring method of raising hands and lifting arms, the workers' arms are prone to soreness, making it inconvenient to carry out the wiring operation and not conforming to ergonomics. Therefore, a detachable secondary cabinet for a ring main unit cabinet is now proposed. Content of the Utility Model
[0004] The purpose of the utility model is to solve the drawbacks in the prior art that in the wiring method of raising hands and lifting arms, the workers' arms are prone to soreness, making it inconvenient to carry out the wiring operation and not conforming to ergonomics, and to propose a detachable secondary cabinet for a ring main unit cabinet.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] The detachable secondary cabinet for a ring main unit cabinet includes a ring main unit cabinet body. A secondary cabinet body is arranged on the top of the ring main unit cabinet body. On one side of the ring main unit cabinet body, support rods are symmetrically and fixedly connected. A fixing block for fixing the secondary cabinet body is arranged inside the support rods. On one side of the secondary cabinet body, connection blocks are symmetrically and fixedly connected. A fixing groove for inserting the fixing block is formed on one side of the connection block.
[0007] Preferably, guiding grooves are symmetrically formed on the top of the ring main unit cabinet body. Guiding rods are symmetrically and fixedly connected to the bottom of the secondary cabinet body. The guiding rods are slidably connected with the guiding grooves.
[0008] Preferably, the bottom of the secondary cabinet body is attached to the top of the ring main cabinet body, and one side of the secondary cabinet body is attached to the support rod.
[0009] Preferably, an installation groove is formed at the top of the support rod, a moving port communicating with the inside of the installation groove is formed on the outer wall of the support rod, the fixing block is slidably connected to both the moving port and the fixing groove, a rectangular spring is sleeved outside the fixing block located inside the installation groove, one end of the rectangular spring is fixedly connected to the inner wall of the installation groove, the other end of the rectangular spring is fixedly connected to a limiting plate, the limiting plate is fixedly connected to the fixing block, the limiting plate is slidably connected to the inner wall of the installation groove, and an inclined surface for the connecting block to press against is arranged on one side of the fixing block.
[0010] Preferably, a lifting groove is formed at the bottom of the moving port, a lifting port communicating with the inside of the lifting groove is formed on the outer wall of the support rod, an L-shaped lifting rod is slidably connected inside the lifting groove, the lifting rod is slidably connected to the lifting port, a moving groove for the lifting rod to insert into is formed at the bottom of the fixing block, the cross section of the moving groove is arranged in a right triangle, and the top of the lifting rod is arranged in an arc shape.
[0011] Preferably, a fixed base is fixedly connected to the bottom of the ring main cabinet body.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. When the device is in use, control the two lifting rods to move upward by hand. The lifting rods will move upward to press against the moving groove and make the fixing block move into the installation groove until one side of the fixing block located inside the fixing groove moves into the moving port, and then the secondary cabinet body can be disassembled and taken out from the top of the ring main cabinet body. After taking out, the secondary cabinet body can be placed on a relatively low table, and then the worker can perform wiring operations inside the secondary cabinet body. There is no need to hold up the hand and lift the arm for wiring operations, which is more convenient and in line with ergonomics.
[0014] 2. When the device is in use, place the guide rod at the bottom of the secondary cabinet body in the guide groove, and then control the secondary cabinet body to move towards the support rod. The secondary cabinet will press against the inclined surface through the connecting block and make the fixing block move into the installation groove, and will stretch the rectangular spring. When the fixing groove is aligned with the moving port, the fixing block will be pushed into the fixing groove under the action of the restoring force of the rectangular spring, so that the secondary cabinet can be quickly fixed on the top of the ring main cabinet body, which is more convenient.
