Intrinsically-safe multi-functional controller

Abstract

The invention relates to an intrinsically-safe multi-functional controller which comprises an organic glass shell and a circuit board of the intrinsically-safe multi-functional controller, wherein the circuit board is arranged in the shell; and the intrinsically-safe multi-functional controller is characterized in that circuits of the intrinsically-safe multi-functional controller comprise a direct-current and pulse power circuit, a master pulse control circuit, an auxiliary control circuit, a time-delay circuit, a direct-current water-jet guided circuit, a plug and a socket, wherein the plugand the socket are used for implementing the connection of internal input and output lines of the multi-functional controller, realizing the multi-functional control applications of the controller, and connecting external control components; the plug and the socket are arranged on the shell; the intrinsically-safe multi-functional controller can be formed into a multi-functional intrinsically-safe remote-control electromagnetic starter, and a remote control and self-resetting feed switch can be formed just by arranging the intrinsically-safe multi-functional controller on a feed switch; and the intrinsically-safe multi-functional controller can perform ultra-long-distance centralized control and multidirectional joint control.

Description

technical field [0001] The utility model belongs to an electrical control device, in particular, it is used in various explosion-proof vacuum electromagnetic starters in coal mines, in explosion-proof vacuum feed switches, and in the electric control boxes of fully mechanized excavators. function controller. technical background [0002] At present, all the existing explosion-proof electrical companies produce mining explosion-proof and intrinsically safe vacuum electromagnetic starters. The maximum joint control distance does not exceed 350 meters, and the control method can only be controlled in one direction and cannot be controlled in multiple directions. No signal reflects indication. The explosion-proof feed switch produced cannot realize remote control and self-resetting functions. For this reason, the monitoring center of the coal mine is only a monitoring center. The monitoring center cannot find problems and carry out rapid control, and it is difficult to truly a...

Problems solved by technology

[0002] At present, all the existing explosion-proof electrical companies produce mining explosion-proof and intrinsically safe vacuum electromagnetic starters. The maximum joint control distance does not exceed 350 meters, and the control method can only be controlled in one direction and cannot be controlled in multiple directions. No signal reflects indication

The explosion-proof feed switch produced cannot realize remote control and self-resetting functions

For this reason, the monitoring center of the coal mine is only a monitoring center, and the monitoring center cannot play the role of quickly controlling problems, and it is difficult to truly achieve safe production.
