Current release circuit of elevator control cabinet

Abstract

The invention provides a current release circuit of an elevator control cabinet. The current release circuit comprises a PCB, a band-type brake coil binding post, an output contactor coil binding post, a power contactor coil binding post, a door lock contactor coil binding post, a safety contactor coil binding post, a band-type brake maintaining coil binding post, resistors for absorbing contactor currents and capacitors for absorbing the contactor currents. The PCB is provided with welding positions connected to the binding posts. By arranging the band-type brake coil binding post, the output contactor coil binding post, the power contactor coil binding post, the door lock contactor coil binding post, the safety contactor coil binding post, the band-type brake maintaining coil binding post, the resistors for absorbing the contactor currents and the capacitors for absorbing the contactor currents on the PCB, modularized work is realized in the wiring process, the cost is lowered, and the assembly efficiency is improved.

Description

technical field [0001] The invention belongs to the field of elevator control cabinets, in particular to an elevator control cabinet current release circuit. Background technique [0002] In the existing technology, the current release part of the absorbing contactor involved is to form a loop through the connection of each wire to achieve the purpose of control. The disadvantage is that the structure is complicated. Since each wire harness must be After production, it is inevitable that there will be missing wiring, and there will be technical problems such as time-consuming, laborious, and low work efficiency when finding problems. Contents of the invention [0003] In view of this, the present invention aims to propose a current releasing circuit of the elevator control cabinet with simple structure and convenient use, so as to realize efficient and convenient absorbing contactor releasing current. [0004] In order to achieve the above object, technical solution of th...
