A high pressure resistant control box

Abstract

The invention relates to the technical field of control boxes, and in particular to a high pressure-resistant control box. The high pressure-resistant control box comprises a box body and a control box panel, wherein the box body is connected with a control box panel through a hinge; buttons and indicator lights are in threaded connection on the outer wall of the control box panel; sealing rings are arranged at joints of the control box panel and the buttons as well as the control box panel and the indicator lights; bolt columns are welded on the box body; and the sealing property between thebox body and the control box panel is improved by the cooperation of the bolt columns and the bolts. The high pressure-resistant control box provided by the invention has the beneficial effects that the buttons and the indicator lights are in threaded connection on the control box panel and the sealing rings are arranged at the joints to meet the watertight requirement; the bolt columns are weldedon the box body and the sealing property between the box body and the control box panel is improved through bolted connection; the bolts are arranged on the entire control box panel to further improve the sealing property between the control box panel and the box body; and therefore, the control box can work normally under the pressure of water 40 meters below the water surface and can meet the water pressure requirements of special ships.

Description

technical field [0001] The invention relates to the technical field of control boxes, in particular to a high-voltage resistant control box. Background technique [0002] The control box is suitable for opening factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings, living quarters, etc., in the low-voltage power grid system with AC 50HZ and rated working voltage of AC 380V, as power, lighting distribution and Used for motor control, suitable for indoor wall-mounted and outdoor floor-mounted power distribution equipment. It is also used in AC 50HZ, voltage below 500V power system as fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. The control methods include direct start control, star delta step-down start control, self-coupling Various control methods such as step-down start control, inverter start control, soft start control, etc., and isolation switches...

AI Technical Summary

Problems solved by technology

[0003] The current control box meets the protection level IP68, can withstand the pressure of 10 meters of water pressure, and can be used underwater for 36 hours. With the development of the industry, some ships have higher requirements for equipment. The current control box cannot meet the requirements of special ships. pressure requirements
