[0001] This utility model relates to an insulation isolation device, specifically an insulation isolation device for a control cabinet busbar, belonging to the field of control cabinet technology. Background Technology

[0002] The main function of a busbar in a power system is to collect, distribute, and transmit electrical energy. It connects multiple power sources or loads together, enabling efficient power transmission and distribution. Because the voltage transmitted through busbars is excessively high, isolation components are needed to protect them and improve the safety of the control cabinet.

[0003] According to patent number CN217240242U, an insulating isolation component for copper busbars in a dense busbar trunking system is disclosed, which includes a protective cover. The protective cover consists of a protective cover body, an outer cover plate, and an inner cover plate. An insulating fixing assembly is provided inside the protective cover body. The insulating fixing assembly includes two side plates, and a fixing plate is provided on the lower surface of each side plate.

[0004] The above-mentioned solution can absorb heat energy upwards from the protective cover during implementation, preventing the temperature inside the cover from becoming too high and ensuring that the heat inside the cover is effectively dissipated. However, the above-mentioned solution is difficult to prevent accidents caused by operators accidentally touching live parts during implementation. Since the busbar is usually exposed inside the control cabinet, staff may accidentally touch the live busbar when inspecting or operating the control cabinet, causing safety accidents. Therefore, we provide a control cabinet busbar insulation isolation device to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a control cabinet busbar insulation isolation device to solve the above-mentioned problems, so as to solve the problem that the control cabinets in the prior art usually do not have the function of protecting live parts, which easily increases the risk of electric shock accidents to operators.

[0006] This utility model is achieved through the following technical solution: a control cabinet busbar insulation isolation device, including a control cabinet body, a busbar is provided inside the control cabinet body, an isolation box is fixedly connected inside the control cabinet body, a protective door is hinged to the outer surface of the isolation box, an insulating isolation plate is fixedly connected inside the isolation box, a current sensor is fixedly installed on the inner wall of the protective door, two electromagnetic locks are fixedly installed on the outer surface of the protective door, and a controller is fixedly installed on the outer surface of the protective door.

[0007] Preferably, a set of indicator lights is fixedly installed on the outer surface of the protective door, and a set of limiting plates is fixedly connected inside the isolation box, the limiting plates serving to limit the busbar.

[0008] Preferably, each of the limiting plates is provided with a movable clamping plate on its exterior, and a telescopic spring is fixedly connected to the outer surface of each movable clamping plate. The end of each telescopic spring away from the movable clamping plate is fixedly connected to the protective door. The telescopic spring can provide the movable clamping plate with sufficient elastic potential energy.

[0009] Preferably, a set of mounting blocks are fixedly connected to the outer surface of the isolation box, and each mounting block is fixedly connected to the control cabinet. The mounting blocks provide stable support for the isolation box.

[0010] Preferably, the control cabinet is internally fixedly connected to an installation strip, and a set of cable trays is externally fixedly installed on the installation strip. Each cable tray is adapted to the busbar, and the installation strip has a heat dissipation function.

[0011] Preferably, a set of top fixing plates are fixedly connected to the top surface of the control cabinet, and a flexible sleeve is fixedly connected inside each top fixing plate. The flexible sleeve is used to bind and fix the busbar.

[0017] This utility model provides an insulation and isolation device for the busbar of a control cabinet.

[0018] Please see Figure 1 and Figure 2 The device includes a control cabinet 1, with a control cabinet door 18 hinged to its outer surface via a pin. An electrical hazard warning sticker is affixed to the outer surface of the control cabinet door 18 to remind unauthorized personnel not to operate the control cabinet, thus preventing accidents caused by operational errors and improving the practicality of the device. The structural components shown in the accompanying drawings are illustrative examples, and their specific implementation should be adapted and optimized based on the functional requirements, assembly conditions, and process limitations of the actual application scenario, taking into account the structural parameters, dimensions, and connection methods.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The control cabinet 1 is equipped with a busbar 2 inside. A set of top fixing plates 16 are fixedly connected to the top surface of the control cabinet 1. Each top fixing plate 16 is fixedly connected to a flexible sleeve 17. The busbar 2 slides inside the flexible sleeve 17. The busbar 2 is the structure for transmitting power to the device. The surface of the busbar 2 is wrapped with a layer of cross-linked polyolefin elastomer insulating film to reduce the risk when the busbar 2 transmits power. The flexible sleeve 17 is made of silicone rubber, which has excellent heat resistance, cold resistance, electrical insulation and excellent elasticity. The flexible sleeve 17 allows the device to bind busbars 2 of different sizes, thereby completing the installation of the busbar 2 and ensuring the stability of the busbar 2 in use.

[0020] Please see Figure 2 , Figure 3 and Figure 4The control cabinet 1 is internally fixedly connected to an installation strip 14, and an external set of cable trays 15 are fixedly installed on the installation strip 14. Each cable tray 15 is adapted to the busbar 2. The cable tray 15 is used to fix the bottom end of the busbar 2 and to provide conditions for the wiring of the control cabinet circuit. It is convenient for the staff to connect the cables to the cable tray 15 to complete the collection, distribution and transmission of power. The installation strip 14 provides stable support for the installation of the cable tray 15 and the busbar 2. At the same time, the installation strip 14 has ventilation slots inside to facilitate the heat dissipation device of the current transmitted by the busbar 2, so as to prevent the temperature of the busbar 2 from being too high and affecting the use of the device.

[0021] Please see Figure 3 An isolation box 3 is fixedly connected inside the control cabinet 1. A set of mounting blocks 13 is fixedly connected to the outer surface of the isolation box 3. Each mounting block 13 is fixedly connected to the control cabinet 1. The mounting blocks 13 provide stable support for the installation of the control cabinet 1, improving the stability of the control cabinet 1. The isolation box 3 provides shielding and protection for the busbar 2, preventing operators from accidentally touching the live busbar 2 and affecting their safety and health, thus improving the safety of the device.

[0022] Please refer to it again. Figure 2 , Figure 3 and Figure 4 The outer surface of the isolation box 3 is hinged with a protective door 4, and the interior of the isolation box 3 is fixedly connected with an insulating isolation plate 5. The isolation box 3 and the protective door 4 can shield the busbar 2, preventing the busbar 2 from being directly exposed in the control cabinet 1, and preventing operators from accidentally touching the busbar 2 and being injured. The insulating isolation plate 5 is made of plastic and is used to isolate the space between adjacent busbars 2, so as to prevent the failure of a certain busbar 2 from affecting the whole device, limiting the scope of the failure, preventing the failure from escalating, and protecting the safety of equipment and personnel.

[0023] A current sensor 6 is fixedly installed on the inner wall of the protective door 4, and a controller 8 is fixedly installed on the outer surface of the protective door 4. When the protective door 4 is closed, the end of the current sensor 6 is in contact with the busbar 2, which can monitor and measure the current flowing in the busbar 2, and convert the detected current information into an electrical signal or other form of information and upload it to the controller 8. The controller 8 is electrically connected to other electrical components of the device through cables. The controller 8 can control the operation of other electrical components. When the controller 8 receives the signal from the current sensor 6, it can determine whether the busbar 2 is a live conductor based on the signal.

[0024] Two electromagnetic locks 7 are fixedly installed on the outer surface of the protective door 4. The electromagnetic locks 7 are of DSN or DSW type and consist of an electromagnet, a lock body, and a control circuit. They can receive signals from the controller 8. When the current sensor 6 detects that the busbar 2 is energized, the controller 8 controls the electromagnetic locks 7 to remain in the engaged state. At this time, the protective door 4 cannot be opened to prevent operators from accidentally touching the live parts. When the current sensor 6 detects that the busbar 2 is de-energized, the controller 8 controls the electromagnetic locks 7 to disengage. At this time, the engaging force in the electromagnetic locks 7 disappears, and the operator can open the protective door 4 to operate the busbar 2. This effectively prevents the operator from being injured by accidentally touching the live busbar 2 during maintenance or other related work, and improves the protection effect for the operator.

[0025] A set of indicator lights 9 are fixedly installed on the outer surface of the protective door 4. The indicator lights 9 can change light under the control of the controller 8. When the current sensor 6 detects current in the busbar 2, the controller 8 controls the indicator lights 9 to show red, reminding the operator that the busbar 2 is in a live state and the protective door 4 cannot be opened. When the busbar 2 is de-energized, the indicator lights 9 show green. At this time, the operator can open the protective door 4 and perform maintenance and other operations on the busbar 2.

[0026] Please see Figure 4 Inside the isolation box 3, a set of limiting plates 10 are fixedly connected. Each limiting plate 10 is provided with a movable clamping plate 11 on its outside. Each movable clamping plate 11 is fixedly connected with a telescopic spring 12 on its outer surface. The end of each telescopic spring 12 away from the movable clamping plate 11 is fixedly connected to the protective door 4. The limiting plates 10 and the movable clamping plates 11 are both made of silicone rubber, which can clamp and limit the busbar 2 to a certain extent, so that the busbar 2 remains fixed inside the isolation box 3. The telescopic spring 12 enables the movable clamping plate 11 to stably clamp the busbar 2, thereby improving the stability of the device in fixing the busbar 2.

[0027] Working principle: In use, the operator first passes the busbar 2 through the flexible sleeve 17 and fixes the bottom end of the busbar 2 to the cable tray 15 with bolts. Then, the cable tray 15 is connected to other electrical equipment through cables. When the operator wants to operate or repair the internal parts of the control cabinet 1, he first opens the control cabinet door 18 and observes the color of the indicator light 9. If the indicator light 9 shows red, the busbar 2 is in a live state. At this time, the operator needs to shut off the current in the busbar 2 to avoid accidental contact with live parts and injury. When the current in the busbar 2 is shut off, the current sensor 6 transmits the detection signal to the controller 8. The controller 8 controls the electromagnetic lock 7 to open according to the signal, thereby canceling the locking state of the protective door 4. At this time, the operator can operate the busbar 2, which greatly improves the safety of the device.
