Problems solved by technology

In the prior art, the electromagnetic starter can measure the liquid level height and pipeline flow of the coal mine underground water tank in real time and automatically control the drainage of the water pump. It has been widely used and promoted in the informatization and automatic unattended management of the coal mine underground water tank. But there are some shortcomings: when the water pump or electromagnetic starter fails to stop working, and the staff cannot reach the site in time, the amount of accumulated water will continue to rise, which will not only cause damage to the site equipment, but also endanger the safety of miners

Abstract

The invention belongs to the technical field of electromagnetic starters and specifically relates to a mine explosive-proof intrinsically safe dual-circuit vacuum electromagnetic starter. The invention solves technical problems and provides the dual-circuit vacuum electromagnetic starter capable of measuring liquid level of a shaft sump and pipeline flow of a mine and automatically controlling two water pumps for water discharge. The technical scheme is that the mine explosive-proof intrinsically safe dual-circuit vacuum electromagnetic starter includes a shell body inside provided with two independent explosive-proof cavities; the two independent explosive-proof cavities are respectively inside provided with a host and a standby machine; and each of the host and the standby machine includes a comprehensive protector BH1 and a vacuum contactor KM1. The mine explosive-proof intrinsically safe dual-circuit vacuum electromagnetic starter provided by the invention is suitable for the field of electromagnetic starters.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic starters, in particular to a mine flameproof and intrinsically safe double-circuit vacuum electromagnetic starter. Background technique [0002] At present, the pipeline flow monitoring and water pump automatic drainage control system in coal mines are usually mainly composed of several independent modules such as the main controller, sensors, electromagnetic starters, water pumps and power supplies; Liquid level value, and pass the flow information and liquid level information to the main controller. In the prior art, the electromagnetic starter can measure the liquid level height and pipeline flow of the coal mine underground water tank in real time and automatically control the drainage of the water pump. It has been widely used and promoted in the informatization and automatic unattended management of the coal mine underground water tank. But there are some shortcomings: when the wate...
