Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a medium-voltage switchgear structure. Background Technology

[0002] In existing medium-voltage switchgear, circuit breaker compartments typically lack effective automatic lighting. When workers need to open the circuit breaker compartment for inspection, maintenance, or other operations, they often need to carry additional lighting tools, such as flashlights. This not only causes inconvenience to the operation but may also lead to operational errors or safety hazards due to insufficient lighting.

[0003] Although some medium-voltage switchgear is equipped with lighting fixtures, the position and orientation of these fixtures are fixed and cannot be adjusted according to the actual layout and lighting needs inside the circuit breaker compartment, resulting in poor lighting in some areas. Furthermore, the lighting fixtures typically require manual operation and do not automatically turn on after the circuit breaker compartment is opened, making them inconvenient to use and reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies where lighting switches usually require manual operation and cannot be automatically turned on after the circuit breaker compartment is opened, which is not convenient to use and reduces work efficiency. Therefore, a medium-voltage switch cabinet structure is proposed.

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

[0006] A medium-voltage switchgear structure includes a switchgear body, a circuit breaker compartment door for sealing the circuit breaker compartment is rotatably provided on the side end of the switchgear body, a lighting fixture for illuminating the circuit breaker compartment is provided in the circuit breaker compartment, and an adjustment component is provided in the switchgear body for adjusting the position and orientation of the lighting fixture.

[0007] To facilitate the automatic activation of lighting fixtures after the circuit breaker compartment door is opened, an opening and closing assembly is provided between the switch cabinet and the circuit breaker compartment door. The opening and closing assembly is used to switch the lighting fixtures on and off by detecting the opening and closing of the circuit breaker compartment door.

[0008] In one possible design, the regulating assembly includes a connecting pipe fixed to the circuit breaker compartment, a threaded lamp holder fixed to the side end of the connecting pipe, a lighting fixture threadedly connected to the threaded lamp holder, a wire for supplying power to the lighting fixture being provided in the threaded lamp holder, and a switching circuit electrically connected to the wire in the lighting fixture being provided in the switch cabinet.

[0009] In one possible design, the connecting pipe is a stainless steel corrugated pipe.

[0010] In one possible design, the connecting pipe can also be a high-strength plastic pipe.

[0011] In one possible design, the opening and closing assembly includes a slot formed inside the switch cabinet, an active infrared beam sensor fixed in the slot, an opening and closing plug matching the slot fixed on the side end of the circuit breaker compartment door, the active infrared beam sensor being connected to the switch circuit wires, and the active infrared beam sensor closing the lighting fixture after the opening and closing plug is inserted into the slot.

[0012] The active infrared beam sensor emits infrared light through its transmitting tube and detects the reflected light through its receiving tube. When the circuit breaker compartment door is closed, the opening and closing plug is inserted into the corresponding slot. The infrared light is blocked and reflected by the opening and closing plug. When the active infrared beam sensor receives the reflected light, it cuts off the switch circuit and turns off the lighting fixture. Conversely, if the infrared light is not blocked and reflected by the opening and closing plug, the active infrared beam sensor does not receive the reflected light and connects the switch circuit to turn on the lighting fixture.

[0013] In one possible design, when the opening / closing plug is not fully inserted into the slot, the reflected light received by the active infrared beam sensor will not cut off the switching circuit to turn off the lighting fixture.

[0014] In this application, the active infrared beam sensor emits infrared light through its transmitting tube and detects the reflected light through its receiving tube. When the circuit breaker compartment door is closed, the opening and closing plug is inserted into the corresponding slot. The infrared light is blocked and reflected by the opening and closing plug. When the active infrared beam sensor receives the reflected light, it cuts off the switch circuit and turns off the lighting fixture. Conversely, when the infrared light is not blocked and reflected by the opening and closing plug, the active infrared beam sensor does not receive the reflected light and connects the switch circuit to turn on the lighting fixture.

[0015] Beneficial effects: In this utility model, the medium-voltage switchgear structure, by setting an adjustment component, can flexibly adjust the position and orientation of the lighting fixtures according to the actual layout and lighting needs inside the circuit breaker room. For example, when new equipment or components are added to the circuit breaker room, the angle of the stainless steel corrugated pipe can be bent or the angle of the high-strength plastic pipe can be adjusted to direct the lighting fixtures towards the areas requiring focused lighting, ensuring that all areas inside the circuit breaker room receive good lighting, thus improving the lighting effect and practicality.

[0016] In this utility model, the design of the opening and closing components of the medium-voltage switchgear structure enables the automatic switching function of the lighting fixtures. When the circuit breaker compartment door is open, the active infrared beam sensor does not receive reflected light, automatically connecting the switching circuit to turn on the lighting fixtures, providing timely and sufficient lighting for the staff without manual operation, thus improving work efficiency and ease of operation. When the circuit breaker compartment door is closed, the opening and closing block blocks the reflected infrared light, and the active infrared beam sensor cuts off the switching circuit to turn off the lighting fixtures, saving energy.

[0017] In this invention, the active infrared beam sensor and the opening / closing plug in the opening / closing assembly can accurately detect the opening / closing status of the circuit breaker compartment door. Furthermore, when the opening / closing plug is not fully inserted into the slot, the lighting fixtures remain on, preventing flickering during door opening and improving the reliability and stability of the lighting system, thus providing a safer and more reliable working environment for staff.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In one embodiment: Refer to Figures 1-3 A medium-voltage switchgear structure, applied in the field of switchgear technology, includes a switchgear body 1. A circuit breaker compartment door 2, used to seal the circuit breaker compartment, is rotatably connected to the side end of the switchgear body 1 via a rotating shaft. A mounting plate 3 for installing circuit breakers is fixed inside the circuit breaker compartment. Lighting fixtures 9 are installed inside the circuit breaker compartment to illuminate it.

[0024] An adjustment assembly is installed inside the switch cabinet 1 to adjust the position and orientation of the lighting fixture 9. The adjustment assembly includes a connecting pipe 7 fixed to the circuit breaker compartment. The connecting pipe 7 can be made of stainless steel corrugated pipe or a high-strength plastic pipe. A threaded lamp holder 8 is fixed to the side end of the connecting pipe 7. The lighting fixture 9 is threadedly connected to the threaded lamp holder 8, which contains a wire supplying power to the lighting fixture 9. The switch cabinet 1 contains a switch circuit electrically connected to the wires inside the lighting fixture 9. During actual installation, the position and orientation of the lighting fixture 9 can be changed by bending the stainless steel corrugated pipe or adjusting the angle of the high-strength plastic pipe, according to the specific layout and lighting requirements inside the circuit breaker compartment, ensuring good lighting in all areas of the circuit breaker compartment.

[0025] In another embodiment: Refer to Figures 1-3 An improvement upon embodiment 1: The opening and closing assembly is positioned between the switch cabinet 1 and the circuit breaker compartment door 2, used to switch the lighting fixture 9 on and off by detecting the opening and closing of the circuit breaker compartment door 2. The opening and closing assembly includes a slot 5 formed within the switch cabinet 1, an active infrared beam sensor 6 fixed within the slot 5, and an opening and closing plug 4 matching the slot 5 fixed to the side end of the circuit breaker compartment door 2. The active infrared beam sensor 6 is connected to the switch circuit wires.

[0026] The working principle of the active infrared beam sensor 6 is as follows: its internal emitting tube emits infrared light, and the receiving tube detects the reflected light. When the circuit breaker compartment door 2 is closed, the opening / closing plug 4 is inserted into the corresponding slot 5. The infrared light is blocked and reflected by the opening / closing plug 4. When the active infrared beam sensor 6 receives the reflected light, it cuts off the switching circuit, thereby turning off the lighting fixture 9. When the circuit breaker compartment door 2 is open, the infrared light is not blocked and reflected by the opening / closing plug 4. When the active infrared beam sensor 6 does not receive the reflected light, it connects the switching circuit, turning on the lighting fixture 9. In addition, when the opening / closing plug 4 is not fully inserted into the slot 5, the reflected light received by the active infrared beam sensor 6 will not cut off the switching circuit, and the lighting fixture 9 remains on, which can indicate the opening and closing status of the door to the operator.

[0027] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
