Description

Technical Field

[0001] The invention relates to the field of starter cabinets, and in particular to an integrated high-voltage solid-state soft starter cabinet. Background Art

[0002] High-voltage solid-state soft start cabinet is a new type of medium- and high-voltage motor soft starter, mainly suitable for medium- and high-voltage AC motors of 10KV and below. It adopts advanced DSP control technology and power electronics technology. The main components are three-phase anti-parallel thyristors and their electronic control circuits connected in series between the power supply and the controlled motor. By controlling the conduction angle of the three-phase anti-parallel thyristors, the input voltage of the controlled motor can be changed according to different requirements, thereby achieving different functions. Specifically, it adopts a combination of computer control technology and power electronics technology. The switching elements of the main circuit adopt high-voltage and high-power thyristors. By controlling the thyristors, the output voltage and starting current are controlled and adjusted. According to the starting conditions, it is effectively controlled to achieve smooth start and stop of the motor.

[0003] The Chinese patent application with announcement number CN218733958U discloses an energy-saving and low-consumption high-voltage solid-state soft-start cabinet, comprising a cabinet, an outer wall of the cabinet is provided with a firm plate, an outer wall of the firm plate is provided with a filter, a control panel is provided on one side of the cabinet, a cabinet door is provided below the control panel, a wire group is provided inside the cabinet, a heat dissipation fan is provided on the inner side of the firm plate, a motor is provided on one side of the heat dissipation fan, and a temperature sensor is provided on one side of the motor; the utility model is provided with a cabinet, a filter, a heat dissipation port, a heat dissipation fan, a motor and a temperature sensor. When the soft-start cabinet is used, the temperature sensor senses the internal temperature of the cabinet. When the temperature is too high, the motors on both sides drive the heat dissipation fans to dissipate heat inside the cabinet, the filter filters and ventilates external dust, the heat dissipation port assists in heat dissipation, the heat dissipation effect is good, and the heat dissipation efficiency of the soft-start cabinet is increased.

[0004] During use, the existing high-voltage solid-state soft start cabinet is generally controlled by an external control panel. However, when an internal fault occurs, the interior of the cabinet still needs to be inspected. Since the equipment is connected to high voltage electricity, it is generally necessary to cut off the power during maintenance. Since there are many wiring harnesses that need to extend outward in the cabinet, and most of the multi-directional wiring harnesses are energized, simply cutting off the power supply cannot ensure that the cabinet is completely powered off. There may still be current inside, which affects the safety of the maintenance personnel and the cumbersomeness before maintenance. In addition, since it is in a closed state for a long time, the internal electrical appliances will generate high temperature when working, and the colloid of the internal wires will produce harmful gases when heated. Opening the cabinet for maintenance will cause maintenance personnel to inhale them. Long-term maintenance will affect the maintenance personnel, and when a fire occurs inside the cabinet, it is impossible to extinguish the fire in the first time, which affects the safe use of the cabinet.

[0030] Through the cooperation of the positioning ring 306 and the annular groove 304, the rotating drum 305 can be positioned and rotated, and when the supporting frame 201 moves downward, it can drive the supporting frame 201 to slide along the limiting rod 301, and at the same time, the limiting block 307 moves in the through groove 302, so that the limiting block 307 moves to a position flush with the limiting groove 303.

[0031] Furthermore, in the above structure, a toggle plate 308 is installed on the outer side of the rotating drum 305, a sliding cavity 309 is opened on the toggle plate 308, a positioning groove 310 is opened at the lower part of the inner wall of the supporting frame 201, a synchronous frame 311 is slidingly connected in the positioning groove 310, a positioning rod 312 is installed above the synchronous frame 311, and the positioning rod 312 is slidingly connected to the corresponding sliding cavity 309, an output end of an electric telescopic rod 313 is installed on one side of the synchronous frame 311, and the electric telescopic rod 313 is fixedly connected to the inner wall of the supporting frame 201.

[0032] The synchronous frame 311 is driven to move by the electric telescopic rod 1 313, so that the synchronous frame 311 drives the positioning rod 1 312 to slide in the sliding cavity 1 309, so that the toggle plate 308 drives the rotating drum 305 to rotate, so that the limit block 307 can be engaged or disengaged in the limit groove 303.

[0035] Furthermore, in the above structure, connecting grooves 407 are symmetrically opened on the outside of the cabinet 001, and multiple groups of air inlet grooves 408 are opened inside the connecting grooves 407, and the air inlet grooves 408 are connected with the inside of the cabinet 001, and the size and number of the air inlet grooves 408 and the ventilation grooves 202 are the same.

[0036] The air inlet slot 408 can connect the inside of the cabinet 001 with the outside, ensuring that the internal air can smoothly enter the cabinet 001.

[0037] Furthermore, in the above structure, the position of one group of air inlet slots 408 is higher than the position of another group of air inlet slots 408, and the interior of the air inlet slots 408 at a higher position is penetrated by the output end of the fire extinguishing dry powder box 405, and a rubber sealing plate 409 is arranged between each group of air inlet slots 408, and the rubber sealing plate 409 is fixedly connected to the inner wall of the cabinet 001, and a plurality of baffles 410 are rotatably connected in the connecting slot 407.

[0038] By moving the supporting frame 201 downward, the ventilation slot 202 on one side can overlap with the air inlet slot 408 at a lower position, so that air can enter the cabinet 001. When the supporting frame 201 is located at a higher position, the ventilation slot 202 on the opposite side can overlap with the air inlet slot 408 at a higher position, so that the fire extinguishing dry powder box 405 can discharge dry powder into the cabinet 001.

[0039] Furthermore, in the above structure, an electric telescopic rod 411 is installed in the connecting groove 407, and the electric telescopic rod 411 is linearly connected to the controller 403, the output end of the electric telescopic rod 411 is rotatably connected to the synchronization rod 412, a sliding cavity 413 is opened on one side of the synchronization rod 412, a positioning rod 414 is installed on the side of the baffle 410 away from the rotational connection position with the connecting groove 407, and the positioning rod 414 is slidably connected to the sliding cavity 413, a plurality of groups of electrode plugs 415 are installed at the bottom of the carrier frame 201, and a plurality of groups of electrode sockets 416 are installed at the bottom of the inner wall of the cabinet 001, and the electrode sockets 416 and the corresponding electrode plugs 415 are in the same vertical and horizontal position.

[0040] The electric telescopic rod 411 can be used to drive the synchronization rod 412 to move, so that the synchronization rod 412 drives the sliding cavity 413 to slide along the positioning rod 414, so that the baffle 410 rotates as a whole, so that the air inlet slot 408 is exposed to the outside, ensuring that air can enter the cabinet 001 along the air inlet slot 408, and the up and down movement of the supporting frame 201 can ensure that the electrode plug 415 is inserted into or detached from the electrode socket 416, and the electrode socket 416 is connected to the external power supply, and the electrode plug 415 is linearly connected to the internal electrical components.

[0041] like Figure 1-12As shown, by moving the carrying frame 201 downward, the slider 206 slides along the slide bar 209 and squeezes the spring 210, and the docking rod 203 slides along the docking tube 204 and squeezes the spring 1 205, so that the ventilation slot 202 on one side coincides with the air inlet slot 408 on one side of the baffle 410, and the ventilation slot 202 on the opposite side is misaligned with the air inlet slot 408 and is sealed with the rubber sealing plate 409, and the electrical connector under the carrying frame 201 is also closed. The pole plug 415 and the electrode socket 416 are plugged in, and the limit block 307 slides along the through slot 302 to a position flush with the limit slot 303. At this time, the electric telescopic rod 1 313 simultaneously engages the limit block 307 and the limit slot 303, thereby fixing the position of the carrier frame 201. At this time, the synchronous rod 412 is driven to rotate by the electric telescopic rod 2 411, so that the baffle 410 is opened, so that the air inlet slot 408 and the ventilation slot 202 connect the cabinet 001 with the outside.

[0042] At this time, the filter exhaust fan 406 is turned on, so that the air inside the cabinet 001 can circulate, ensuring the constant internal temperature and air quality, and the baffle 410 can be automatically closed when the cabinet 001 is not working to prevent dust from entering. When the inside of the cabinet 001 needs to be inspected, the cabinet door 101 is opened at this time, and the spacing signal sensor 402 transmits the signal to the spacing signal receiver 401, so that the controller 403 controls the electric telescopic rod 313 to work, so that the support frame 201 is released from the restriction and moves upward, so that the electrode plug 415 is disengaged from the electrode socket 416, ensuring that the electrical components inside the support frame 201 are powered off.

[0043] And when a fire occurs inside, the smoke sensor 404 will detect a signal and make the supporting frame 201 repeat the above action. At the same time, the baffle 410 is closed, and the ventilation slots 202 and the air inlet slots 408 on the same side are offset, and the ventilation slots 202 and the air inlet slots 408 on the same side of the fire extinguishing dry powder box 405 overlap, so that the interior is in a sealed state. At the same time, the filter exhaust fan 406 continues to work to quickly discharge the internal air and reduce the oxygen content. At the same time, the fire extinguishing dry powder box 405 sprays dry powder fire extinguishing agent, and because the interior is in a negative pressure state, the dry powder fire extinguishing agent can quickly enter, thereby improving the safety of the starter cabinet.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
