Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a mine high-voltage switchgear that facilitates wiring. Background Technology

[0002] In harsh industrial environments such as coal mines and metal mines, high-voltage switchgear is a critical piece of equipment for ensuring the safety and reliability of power supply. It not only contains the primary high-voltage circuit but also integrates the secondary systems necessary for protection, measurement, and control functions. These secondary systems typically consist of various precision components such as relays, programmable logic controllers, fuses, and terminal blocks.

[0003] Electrical components are modularly mounted on guide rails. In order to achieve electrical isolation and physical protection between components, a ring-shaped isolation compartment guide rail is usually installed inside it.

[0004] Because the isolation chamber forms a semi-enclosed, narrow space, the operating space available for operators to perform wiring, debugging, and maintenance is extremely limited. When it is necessary to connect control lines and signal lines from various locations to the terminal blocks of components, the operator's hand and tool movements are severely restricted. This not only greatly affects the efficiency of wiring and makes the wiring work cumbersome and time-consuming, but more importantly, due to the obstructed view and inconvenient operation, it is very easy to cause problems such as unreliable wiring, loose wire clamping, or loose wire connections, which affect the safe and stable operation of the power supply system. Utility Model Content

[0005] In view of the problems of cumbersome wiring and unreliable wiring in existing wiring systems, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a mine high-voltage switchgear that facilitates wiring. Its purpose is to ensure the stable installation of electronic components and to provide sufficient and convenient space for wiring operations.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a mine high-voltage switchgear for easy wiring, including a cabinet and a component mounting assembly. The component mounting assembly includes two side seats arranged in a relative position, and a steel guide rail is detachably installed between the movable ends of the two side seats.

[0008] The side seat includes a U-shaped frame, and a movable module is detachably installed in the inner cavity of the U-shaped frame. An electromagnet is provided inside the U-shaped frame and near the end of the steel guide rail. A magnetic ring coaxial with the electromagnet is installed at the movable end of the movable module and near the electromagnet. The opposing surfaces of the electromagnet and the magnetic ring are in a state of magnetic repulsion.

[0009] As an improved technical solution, a switch for controlling the electromagnet is embedded in the front end face of the U-shaped frame, and an engine compartment is fixed inside the U-shaped frame and near the end face of the electromagnet.

[0010] As an improved technical solution, a fixing channel is provided on one side of the U-shaped frame, and the two ends of the fixing channel are semi-circular.

[0011] As an improved technical solution, the active module includes a Z-shaped plate, on which a guide post coaxial with the magnetic ring is slidably mounted through an opening at one end. The guide post is detachably installed inside the U-shaped frame. A baffle is fixed at one end of the guide post located in the inner hole of the magnetic ring, and a spring is sleeved at the end of the guide post away from the magnetic ring.

[0012] As an improved technical solution, the end of the guide post away from the magnetic ring is provided with a threaded groove, and a second internal hex bolt is threaded onto the guide post through the threaded groove. The front end face of the movable module is provided with a T-shaped hole for the second internal hex bolt to pass through.

[0013] As an improved technical solution, the other end of the Z-shaped plate is provided with a threaded hole, and a first internal hex bolt is threaded onto the Z-shaped plate through the threaded hole, and the first internal hex bolt passes through the cavity on the steel guide rail.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. The present invention comprises a component mounting assembly consisting of two side seats and a steel guide rail. The side seats are modularly and detachably connected to a movable module and a U-shaped frame. The steel guide rail and the movable module are also connected by a threaded detachable connection. The entire component mounting assembly is modularly designed and assembled, which not only facilitates assembly and use, but also allows for direct replacement of the corresponding module if a single module is damaged, thus reducing the later maintenance costs.

[0016] 2. This utility model uses the repulsive force of magnetic force to remove electronic components stuck on steel guide rails from the annular compartment. The terminals of the electronic components are exposed outside the annular cavity, placing them in an open and spacious position. This provides ample space, making wiring, wire alignment, and screw tightening operations easy and intuitive. It not only shortens installation and maintenance time but also ensures that each terminal can be reliably and firmly crimped. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figures 1-4 This is the first embodiment of the present utility model, which provides a mine high-voltage switchgear that facilitates wiring. This mine high-voltage switchgear that facilitates wiring includes a cabinet 1. The cabinet 1 is equipped with circuit breakers, disconnect switches, grounding switches, current transformers, voltage transformers, surge arresters, etc. It also includes a component mounting assembly 2, which is fixed inside the cabinet 1. The component mounting assembly 2 includes two side seats 3 arranged in a relative position. A steel guide rail 4 is detachably installed between the movable ends of the two side seats 3.

[0027] The side seat 3 includes a U-shaped frame 6. A movable module 5 is detachably installed in the inner cavity of the U-shaped frame 6. An electromagnet 8 is provided inside the U-shaped frame 6 and near the steel guide rail 4. A magnetic ring 9 coaxial with the electromagnet 8 is installed at the movable end of the movable module 5 and near the electromagnet 8. The opposing surfaces of the electromagnet 8 and the magnetic ring 9 are in a state of magnetic repulsion.

[0028] The electromagnet 8 generates a magnetic force that repels the magnetic ring 9. Driven by this repulsive force, the Z-shaped plate 51 moves towards the T-shaped hole 62, compressing the spring 54. As the Z-shaped plate 51 moves outward, it simultaneously removes the steel guide rail 4 from the isolation chamber, and simultaneously removes the electronic components stuck on the steel guide rail 4 from the annular chamber. The terminals of the electronic components are exposed outside the annular cavity, providing an open and spacious environment. This provides ample space, making wiring, wire alignment, and screw tightening easier and more intuitive. This not only shortens installation and maintenance time but also ensures that each terminal is reliably and securely crimped.

[0029] The front end face of the U-shaped frame 6 is embedded with a switch 10 for controlling the electromagnet 8. The machine compartment 7 is fixed inside the U-shaped frame 6 and near one end face of the electromagnet 8. The electromagnet 8 is fixed to the front end face of the machine compartment 7. The machine compartment 7 is equipped with a battery.

[0030] A fixing channel 61 is provided on one side of the U-shaped frame 6, and the two ends of the fixing channel 61 are semi-circular. The locking screw passes through the fixing channel 61 and is threaded to the threaded hole on the inner wall of the cabinet 1 to fix the U-shaped frame 6 inside the cabinet 1.

[0031] The active module 5 includes a Z-shaped plate 51. A guide post 55, coaxial with the magnetic ring 9, is slidably mounted on one end of the Z-shaped plate 51. The guide post 55 is detachably installed inside the U-shaped frame 6. A baffle 58 is fixed at one end of the guide post 55 located in the inner hole of the magnetic ring 9. A spring 54 is sleeved at the end of the guide post 55 away from the magnetic ring 9.

[0032] The guide post 55 has a threaded groove 56 at the end away from the magnetic ring 9. The guide post 55 is threaded with a second internal hex bolt 57 through the threaded groove 56. The front end face of the movable module 5 has a T-hole 62 for the second internal hex bolt 57 to pass through.

[0033] The process of installing the active module 5 inside the U-shaped frame 6 is as follows:

[0034] The movable module 5 is inserted longitudinally into the U-shaped frame 6, so that the threaded groove 56 and the T-shaped hole 62 are coaxial. Then, the second hexagon socket bolt 57 is passed through the T-shaped hole 62 and screwed into the threaded groove 56. The movable module 5 is detachably installed inside the U-shaped frame 6 through the threaded connection between the second hexagon socket bolt 57 and the threaded groove 56. This facilitates quick assembly and disassembly of the movable module 5 and the U-shaped frame 6, improves assembly efficiency, and also facilitates the individual replacement of the weakened spring 54 later, reducing the later maintenance cost.

[0035] The other end of the Z-shaped plate 51 has a threaded hole 52. A first hexagon socket bolt 53 is threaded onto the Z-shaped plate 51 through the threaded hole 52. The first hexagon socket bolt 53 passes through the cavity on the steel guide rail 4, and the steel guide rail 4 is fitted to the front end face of the threaded hole 52. The first hexagon socket bolt 53 passes through the cavity of the spring 54 and is then threadedly connected to the threaded hole 52, thus fixing the steel guide rail 4 onto the Z-shaped plate 51. The threaded installation facilitates the assembly and disassembly of the steel guide rail 4 and the movable module 5.

[0036] The component mounting assembly 2 consists of two side seats 3 and a steel guide rail 4. The side seats 3 are modularly and detachably connected together by movable modules 5 and U-shaped frames 6. The steel guide rail 4 and movable modules 5 are also connected by threads. The entire component mounting assembly 2 is modularly designed and assembled, which not only facilitates assembly and use, but also allows for direct replacement of the corresponding module if a single module is damaged, thus reducing the later maintenance costs.

[0037] The working principle of this utility model is as follows: Under normal conditions, under the elastic pressure of the spring 54, the Z-shaped plate 51 is pressed against the rear end, which can hold the electronic components inside the steel guide rail 4.

[0038] When it is necessary to wire electronic components, the electromagnet 8 is turned on to generate a magnetic force that repels the magnetic ring 9. Under the pushing action of the magnetic repulsion, the Z-shaped plate 51 is moved toward the T-shaped hole 62 and the spring 54 is compressed. When the Z-shaped plate 51 moves outward, it will also move the steel guide rail 4 out of the isolation chamber at the same time, and simultaneously remove the electronic components stuck on the steel guide rail 4 from the annular chamber. The wiring terminals of the electronic components are exposed outside the annular cavity.

[0039] When no wiring is required, electromagnet 8 is turned off. Under the elastic reset action of spring 54, the electronic components are reset and moved into the annular compartment. In the unwiring state, they can be stably reset into the annular compartment, which continues to provide effective electrical isolation and physical protection for the electronic components.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
