Problems solved by technology

[0002] The chargers used in the mainland have no special requirements for opening the door and cutting off the power, so the general chargers do not have this function, but Hong Kong has very strict requirements for electrical safety, especially strict requirements for electrical equipment accidental electric shock. If the charger does not have the safety protection measures of opening the door and cutting off the power, it cannot pass the acceptance test.

Abstract

The invention discloses a charger door-opening power outage safety protector comprising a first loop and a second loop. The upper two ends of the first loop are connected in series with power switches. The left end of the second loop is connected in parallel with a second connecting line. A stroke switch is connected in series with the second loop between the second connecting line. A change-over switch and a time relay are successively connected in series with the second connecting line from left to right. A stop button is connected in series with the middle of the second loop. The right end of the second loop is connected in series with a start button and a main contactor. A third connecting line is connected in series with the main contactor. The left end of the lower part of the first loop is connected in series with a change-over switch. A time relay and an overhaul indicating lamp are successively connected in series with the first connecting line from left to right. The charger door-opening power outage safety protector thoroughly solves accidents that non-operating workers opens a door by mistake and suffers from electric shock, satisfies a requirement for electric appliance equipment safety protection in Hong Kong, and is good in practicality and easy to operate.

Description

technical field [0001] The invention relates to the technical field of door-opening and power-off safety protection for a charger, in particular to a door-opening and power-off safety protection for a charger. Background technique [0002] The chargers used in the mainland have no special requirements for opening the door and cutting off the power, so the general chargers do not have this function, but Hong Kong has very strict requirements for electrical safety, especially strict requirements for electrical equipment accidental electric shock. If the charger does not have the safety protection measures of opening the door and cutting off the power, it cannot pass the inspection. Contents of the invention [0003] The object of the present invention is to provide a safety protection for a charger when the door is opened and the power is cut off, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, ...
