Abstract

The invention discloses an explosion-proof electrical control device for extremely cold regions, comprising an electrical control main body, prism components are installed at the four corners of the electrical control main body, and a carapace mechanism is installed at the rear end of the electrical control main body, so that the The carapace mechanism is used to block the impact of external explosion and provide protection to an electrical appliance control body; the invention relates to the technical field of electrical appliance control; the control device can use the non-Newtonian fluid flowing into the butterfly casing plate to utilize the front and rear of the butterfly casing plate. Butterfly mouth 1 and butterfly mouth 1 opened at both ends enable non-Newtonian fluid to be closely attached to Kevlar fiberboard 1 and Kevlar fiberboard 2 at the same time, respectively, and the Kevlar fiber impregnated by non-Newtonian fluid is impacted When , due to the strong shear thickening behavior of the internal non-Newtonian fluid, its resistance to explosion shock increases sharply, which greatly improves the protection effect of the device against external explosion shock.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to an explosion-proof electrical control device used in extremely cold regions. Background technique [0002] The electrical control system is generally referred to as the secondary control loop of electrical equipment. Different equipment has different control loops, and the control methods of high-voltage electrical equipment and low-voltage electrical equipment are also different; The combination of originals is used to realize the control of one or some objects, so as to ensure the safe and reliable operation of the controlled equipment, and its main functions are automatic control, protection, monitoring and measurement; [0003] The control devices on the market cannot effectively block and protect the explosion shock outside the device, and cannot avoid the damage and penetration of the tightness between the device structures caused by the thermal expansion and con...
