Embodiment Construction

[0011] The present invention will be described in detail below in combination with specific embodiments.

[0012] A mine roadway lighting lamp delay shutdown circuit according to the present invention is provided with lighting lamps, and can also be a parallel lighting lamp group. The lighting lamp is connected in series with the contacts of the power-off delay time relay KT and the power-off delay time relay KT, and a parallel switch group is also connected in series in the series circuit. A fuse FU is connected in series on the circuit bus.

[0013] After arbitrarily closing a switch, the power-off delay time relay KT pulls in, the contact of the power-off delay time relay KT closes, and the lighting lamp lights up. After a period of time, the contact of the power-off delay time relay KT is opened, and the lighting lamp goes out. When the lighting lamp is not extinguished, another switch can be closed to prolong the power-on time of the lighting lamp.

Abstract

The invention relates to a mine tunnel lighting lamp delayed turn-off circuit. When workers leave a mine tunnel, lighting equipment of the mine tunnel needs to be turned off, workers need to walk into another section of mine tunnel in the situation that lighting condition is not available if the lighting equipment is turned off directly, and waste of power resources occurs if the lighting equipment is not turned off. The mine tunnel lighting lamp delayed turn-off circuit comprises a lighting lamp, wherein the lighting lamp is in series connection with a power-off delayed time relay KT and a contact of the power-off delayed time relay KT, a switch group with switches which are in parallel connection is in series connection with the series circuit, and a fusible cutout (FU) is connected on a circuit bus in series mode. According to the mine tunnel lighting lamp delayed turn-off circuit, the power-off delayed time relay KT is arranged, the circuit is delayed to be turned off when the circuit is switched on for a while, so that lighting lamp is enabled to be automatically turned off after a period of time, manual lighting lamp turn-off is needless, and thus power resources are further saved.

Description

technical field [0001] The invention relates to a lighting closing circuit, in particular to a mine roadway lighting delay closing circuit. Background technique [0002] Mine roadway lighting is the lifeline to ensure the normal production of mines, and it is also one of the main measures for mine safety production. However, due to the environment and use status of mine roadways, there are many inconveniences in mine roadway lighting. After the staff withdraws from the mine tunnel, they need to turn off the lighting equipment of the mine tunnel, but if they are turned off directly, the staff must go to another section of the mine tunnel without lighting conditions. If the lighting is not turned off, it will cause a waste of power resources. Contents of the invention [0003] The purpose of the present invention is to provide a mine roadway lighting lamp time-delay off circuit without the need for workers to manually turn off the lighting lamp. [0004] The technical s...
