Shock-resistant and flame-retardant independent type low-temperature power distribution cabinet

Abstract

The invention discloses a shock-resistant and flame-retardant independent type low-temperature power distribution cabinet which comprises a cabinet body, a cabinet door and supporting plates, wherein a travel switch is connected into the cabinet body; a movable rod of the travel switch is connected with the cabinet door; a plurality of groups of shock absorption devices are arranged in the cabinet body; a temperature sensor is arranged at the lower end in the cabinet body; a smoke fog sensor is arranged at the upper end of the cabinet body; a control device is arranged on the right side wall in the cabinet body; a gas bottle slot is formed in the upper right end of the cabinet body; a gas bottle chuck is arranged at the left end in the gas bottle slot, and is connected with a steel pipe horizontally arranged in the cabinet body; the lower end of the steel pipe is connected with a plurality of spraying nozzles; and an electromagnetic valve is further arranged on the steel pipe. By the arrangement of the shock absorption device, the shock-resistant and flame-retardant independent type low-temperature power distribution cabinet can buffer force in any direction and absorb shock so as to supply complete shock absorption protection; a carbon dioxide gas bottle is mounted in the gas bottle slot; one bottle has two purposes of cooling and fire extinguishing, and can be automatically opened, so that the labor is saved, and the efficiency is realized; and the travel switch locks the electromagnetic valve to enable the electromagnetic valve to not be opened when the cabinet door is opened, so that personnel can be prevented from being frostbitten, and the shock-resistant and flame-retardant independent type low-temperature power distribution cabinet is high in safety.

Problems solved by technology

[0002] The power distribution cabinet is the final equipment in the power circuit. It is mainly used for the integrated placement of various power distribution components and the monitoring and display of related voltage and current data. The power distribution cabinet is generally placed in a special power distribution room, and a few are placed Outdoors, during the use of power distribution cabinets, one of the more common problems is overheating, and the other is flames caused by circuit short circuits, which will directly affect the normal operation of power distribution cabinets

[0003] For the existing power distribution cabinets, one is to install air-conditioning and cooling equipment in the power distribution room to control the temperature by lowering the ambient temperature. However, the outdoor installed power distribution cabinets can only rely on louver fans for basic ventilation and cooling. Not only the cooling effect It is not good, and it is easy to cause a lot of dust to enter the cabinet, which is difficult to clean, and there is no reasonable solution to the problem of short circuit flames; in addition, because there are a large number of components installed in the power distribution cabinet, it is very difficult to It is easy to cause the connection line to loosen, or even damage the components due to excessive vibration. These are the problems that are often encountered in daily use.

[0004] Chinese patent authorization announcement number CN205092478U discloses a fire prevention electric control cabinet, which uses dry ice to extinguish fire and cool down, but it is equipped with a ventilation device to allow air to circulate inside and outside, and without any heat preservation measures, the internal low temperature environment will be quickly eliminated. , and then return to the high temperature environment again, as in the past, the consumption of dry ice is extremely high, and there is no insurance measure at the same time. If the detection device works and emits dry ice during personnel maintenance, it is easy to cause frostbite to personnel, and its practicality is not high.

[0005] In addition to the problem of overheating and fire, during transportation and installation, and the internal components of the outdoor power distribution cabinet will be subject to greater impact. The existing power distribution cabinet is not equipped with any shock absorption measures, and the impact force is completely caused by Internal components absorb, it is easy to cause line drop or equipment damage, and the authorized announcement number CN203826814U provides a shock-absorbing power distribution cabinet, which uses springs to shock-absorb the entire cabinet, but its impact on the left and right directions and the impact on the The impact shock absorption effect on the internal mounting board is not good. What the power distribution cabinet really needs is the protection of the components on the mounting board, not the protection and shock absorption of the entire power distribution cabinet body.
