Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1-3, the invention relates to an adsorption type electric leakage warning device for a meter cabinet, which comprises a shell, an induction module, an action mechanism, an early warning action module, a power supply module and a switch module. The shell is of a cuboid structure and consists of an upper layer and a lower layer, the upper layer is provided with a rectangular groove body, and the bottom of the rectangular groove body is provided with a red color plate and a green color plate; the induction module is positioned on the lower layer of the shell, can magnetically adsorb the metal shell of the equipment, induces and intercepts the induction voltage of the leakage current on the metal shell of the equipment, and transmits the induction voltage to the early warning action module through a connecting circuit. The action mechanism is connected with the switch module clamping hole and can slide in the rectangular groove body to shield the red color plate or the green color plate. The switch module is connected with the power supply module through the action loop and the early warning action module on the action loop, and the switch module acts after being powered by the power supply module. The early warning action module can judge to switch off or switch on the action loop through the induction voltage of the leakage current intercepted by the induction module. The sensing module, the early warning action module and the power supply module are arranged in the upper layer of the shell, and are not shown in fig. 1 and 2.
The induction module is composed of a magnet and an induction coil, wherein the magnet is positioned in the middle, the induction coil is a coil with the thickness of phi 8-phi 12 and the thickness of 10mm, and the induction coil surrounds the extension of the magnet and is vertical to the magnet adsorption layer. The early warning action module adopts a TLP181-sop4 type photoelectric coupler.
