Problems solved by technology

If the rescuer does not manually disconnect the UPS rescue switch after the rescue is completed, the UPS will continue to discharge, which will affect the service life of the UPS; after the mains is connected, if the rescuer forgets to close it, it will affect the next UPS. rescue
This creates a safety hazard for equipment and rescue

Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] This embodiment provides a UPS rescue control loop for an elevator without a machine room, such as figure 1 with image 3 As shown, the output terminal of the commercial power 1 is connected to the input terminal of the elevator control cabinet 2 to form a commercial power loop. It also includes a UPS power supply 3, the input end of the UPS power supply 3 is connected to the output end of the mains 1, and the output end of the UPS power supply 3 is connected to the elevator control cabinet 2 to form a UPS rescue circuit. Such as image 3 As shown, the horizontal arrangement is the UPS rescue circuit, and the vertical arrangement is the mains circuit, where, image 3 In order to make the control loop clearer, the elevator control cabinet 2 is drawn as two.

[0025] In order to realize the...

Abstract

The invention provides a machine room-free elevator UPS rescue control circuit, which comprises UPS power source, wherein a commercial electricity output end is connected to an input end of an elevator control cabinet to form a commercial electricity circuit; a UPS power source input end is connected to the commercial electricity output end; a UPS output end is connected to the elevator control cabinet to form a UPS rescue circuit; the UPS rescue circuit is parallel to a power-off time-delay time relay; the commercial electricity is connected, the commercial electricity circuit is on and the elevator control cabinet is powered; when the commercial electricity is cut off, the power-off time-delay time relay is cut off after delaying the set time; and within the set time, the UPS rescue circuit is on and the elevator control cabinet is powered to carry out elevator rescue. According to the invention, on the basis that the UPS rescue is ensured by the power-off time-delay time relay, the energy-saving control to the UPS power source is realized; the practicality is strong; and the installation is flexible.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to a UPS rescue control circuit for a machine room-less elevator. Background technique [0002] UPS is an uninterruptible power supply, which is a constant voltage and constant frequency uninterruptible power supply with an energy storage device and an inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine; when the mains is interrupted (accident blackout) At this time, the UPS will continue to supply 220V AC power to the load through the method of inverting the electric energy of the battery inside the machine immediately, so as to maintain the normal operation ...
