Title:
POWER INTERRUPTION LAMP INSPECTION DEVICE FOR ELEVATOR
Document Type and Number:
Japanese Patent JP3188819
Kind Code:
B2
Abstract:
PURPOSE: To provide a power interruption lamp inspection device for an elevator which can easily always inspect whether a power interruption lamp in a riding car and a power supply for the power interruption lamp are good or bad.
CONSTITUTION: A device has a power interruption lamp 9 provided in a riding car and a resistor 15g connected between both ends of a contact 7 to set a resistance value, such that power interruption lamp across both end voltage is almost equalized to power supply voltage of a power interruption lamp power supply when disconnected the power interruption lamp, relating to a lighting circuit of the power interruption lamp of connecting is series the contact 7 closed when put out an illuminating lamp in the riding car and the power interruption lamp power supply 8. The first reference value of voltage value higher than power interruption both end voltage, when the power interruption lamp and its power supply are normal, and the second reference value of voltage value lower than power interruption lamp body end voltage are set, to provide an inspection card 15 having the first comparator 15h of feeding a power interruption lamp break detection signal when the power interruption lamp both end voltage is higher than the first reference value and having the second comparator 15i of feeding a deterioration detection signal of the power interruption lamp power supply when the power interruption lamp both end voltage is lower than the second reference value.
