Description
Technical Field
[0001] The utility model relates to the technical field of power distribution cabinet installation, in particular to a fixed AC low-voltage power distribution cabinet. Background Art
[0002] Electricity is an indispensable condition for scientific and technological progress and social development. The continuous improvement of scientific and technological levels has put forward higher requirements for the reliability and safety of power supply. In the power system, the reliability and safety of power supply are of vital importance. However, the current low-voltage distribution cabinets have problems such as complex structure, cumbersome processing, high product cost, difficult to ensure safety, and inconvenient use. With the increasing application of distribution cabinets, the distribution cabinets in power plants and transformer stations have become important power equipment.
[0003] For example, a fixed AC low-voltage power distribution cabinet with application number CN202320167824.2 includes a cabinet and rollers, and multiple groups of the rollers are distributed in a rectangular shape at the bottom of the cabinet. In this application, after the cabinet moves to the specified position, the output end of the push cylinder pushes the bottom frame through the matching piece, and the bottom frame receives the driving force and links the convex seat until the bottom of the convex seat abuts against the working ground. At this time, the bottom of the convex seat will produce a large friction force with the working ground, and limit the movement of the roller, so as to achieve the fixation and stability of the cabinet, without the need to lock the roller separately. The output end of the push cylinder can be extended further later. At this time, the convex seat has abutted against the working ground. The driving force of the output end of the push cylinder will overcome the gravity of the cabinet and push the cabinet upward in the opposite direction, so as to achieve the vertical height of the cabinet in a stable state. The overall operation is relatively simple, thus ensuring the convenience of using the fixed AC low-voltage power distribution cabinet. However, the fixed AC low-voltage distribution cabinet is not equipped with a cooling device. When an open fire occurs inside the distribution cabinet body and is not discovered in time by the staff, the fire cannot be controlled, which easily causes more wires to catch fire and cause greater losses. Therefore, in view of this, the existing structural deficiencies are studied and improved, and a fixed AC low-voltage distribution cabinet is proposed. Utility Model Content
[0004] The purpose of the utility model is to provide a fixed AC low-voltage distribution cabinet to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixed AC low-voltage power distribution cabinet, comprising a main switch door and an automatic cut-off mechanism, wherein the switch door is rotatably connected to one side of the main body, and the automatic cut-off mechanism is arranged inside the switch door, the interior of the automatic cut-off mechanism includes an identifier fixedly connected to a position on one side of the switch door, and the interior of the identifier is provided with an infrared detection, and a cut-off block is arranged on one side of the infrared detection.
[0006] Preferably, a cooling mechanism is fixedly connected to one side of the automatic cut-off mechanism, and the cooling mechanism includes a processor fixedly connected to one side of the switch door, and an exhaust port is opened inside the processor, and an air inlet is provided on one side of the exhaust port.
[0007] Preferably, a groove is opened inside the main body, and a heat dissipation mechanism is arranged inside the groove, and the heat dissipation mechanism includes a fixed frame movably connected to the internal position of the groove, and a motor is fixedly connected to the inside of the fixed frame, a fan is fixedly connected to one side of the motor, and a dustproof net is arranged on one side of the fan, and a dehumidification plate is arranged inside the fixed frame.
[0008] Preferably, a heat dissipation hole is opened on one side of the groove, and a monitoring module is fixed inside the main body.
[0009] Preferably, a rectifier module is fixedly connected to one side of the monitoring module, and a battery inspection module is arranged at the bottom of the rectifier module.
[0010] Preferably, a battery pack is provided at the bottom of the battery inspection module, and a control switch is provided at the bottom of the battery pack.
[0011] Preferably, a protective plate is fixed to the top of the main body, and a bracket is fixedly connected to the bottom of the main body.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model can immediately identify the presence of open fire inside the main body of the power distribution cabinet through the automatic cutting mechanism and the cooling mechanism. The infrared detection inside the automatic cutting mechanism can immediately identify the presence of open fire inside the main body. The cut-off block is controlled by the identifier to immediately cut off all power supplies to prevent more wires from short-circuiting and burning. The processor connected to one side of the identifier absorbs the hot air with higher temperature inside the main body into the processor, and converts the hot air into a low-temperature humidifier spray through the exhaust port to extinguish the fire, thereby preventing the open fire from being extinguished in time, the fire from increasing, and causing irreparable losses. An arc-shaped protective plate is arranged on the top of the main body to protect the power distribution cabinet. Some power distribution cabinets are located outdoors for a long time. Direct sunlight can make the internal temperature of the power distribution cabinet too high, and the circuit is prone to short-circuiting and catching fire. In bad weather with a lot of rain, the exterior of the power distribution cabinet is easily corroded by rain. The protective cabinet can effectively prevent the power distribution cabinet from being exposed to the sun and corroded by rain, thereby extending the service life of the power distribution cabinet.
[0014] 2. The utility model can maintain a suitable temperature inside the main body of the power distribution cabinet through the setting of the heat dissipation mechanism. The motor drives the fan to rotate so that the hot air inside the main body is discharged to the outside of the main body. The dustproof net on one side of the fixed frame can prevent external dust from entering the power distribution cabinet when the fan rotates. The dustproof net on the top of the fixed frame can prevent dust inside the power distribution cabinet from falling into the inside of the motor and affecting the normal operation of the motor. The dehumidification plates on both sides of the fixed frame are provided with adsorption materials such as activated carbon, which can effectively adsorb the humid gas inside the main body.

The size of the fixed frame 501 is consistent with the groove 4. The motor 502 drives the fan 503 to rotate and discharge the hot air inside the main body 1. The dustproof net 504 is located on the side and top surface of the fixed frame 501, and the dehumidification plate 505 is symmetrically distributed about the vertical center line of the fixed frame 501, so as to absorb the humid gas inside the main body 1 and extend the service life of the distribution cabinet.
