Abstract
The invention discloses a safe interlocking control method for an electric locomotive garage-in motor car. A garage-in motor car key A, a current transformer cabinet key, auxiliary cabinet keys B and a mechanical interlocking device are arranged. Only when the key A is rotated to the locking position, will the keys B be rotated to the unlocking position from the locking position and pulled out. Only when the two keys B are located at the position of the mechanical interlocking device and restored to the locking position from the unlocking position, will the key A be restored to the unlocking position from the locking position and be pulled out. Only when a cabinet door is closed, will the keys B be rotated to the unlocking position from the locking position and be pulled out. Only when the key A is in a closing, namely an unlocking state, will a garage-in motor car contactor be closed to provide electricity to a driving device. The electric and machine interlocking functions are achieved at the same time, the safety of the garage-in motor car is improved, and operators can be effectively prevented from getting an electric shock.
Description
Technical field
The present invention relates to motor-car safety interlocking control method in a kind of electric power machine garage, belong to railway locomotive technical field.
Background technology
Electric locomotive cannot obtain electric energy from contact system and directly drive locomotive when debugging storehouse, test storehouse and keeping in repair in storehouse, need to utilize power drives electric locomotive in storehouse, realizes movement or the outbound of locomotive in storehouse.In storehouse, motor-car power supply mainly contains following several specification: 3 phase AC380V, DC600V, AC220V etc., all surpassed the requirement of the human safety voltage 36V of regulation.Motor-car when operation in carrying out storehouse, if the cabinet door of electrification device place screen cabinet do not have locking (as, auxiliary tank, converter cabinet), operating personal very easily touches electrification device, causes accident of human electric shock.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, and motor-car safety interlocking control method in a kind of electric power machine garage is provided.
The object of the present invention is achieved like this: motor-car safety interlocking control method in a kind of electric power machine garage, is characterized in that taking the following step:
A., motor-car key A in storehouse, converter cabinet key and auxiliary tank key B machinery connection are set and connect device, wherein:
Key A: key A inserts mechanical interlocking device, and rotate to " locking " position, key B could be rotated to " release " position by " locking " position, and can extract; Only have 2 key B all in mechanical interlocking device place, and by " release " bit recovery to " locking " position, could operate key A by " locking " bit recovery to " release ", and can extract;
Key B: can release converter cabinet, the cabinet door of auxiliary tank, when inserting key B, and rotation is to " locking " position, and cabinet door can be opened, and now key B can only, in cabinet door place, can not extract; Only close cabinet door, key B could be rotated to " release " position by " locking " position, and extracts;
B. after driver controller control command is sent, locomotive control microcomputer detects motor-car key switch state in storehouse, if if it is released state in closure, makes motor-car contactless switch closure in storehouse, to actuating device, powers; Otherwise, keep motor-car in storehouse to connect the off-state of hornwork, and report to the police.
The solution of the present invention has electric and mechanical chain function simultaneously, has improved the safety of motor-car in storehouse, can effectively prevent the generation of operating personal electric shock accidents.
Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of the embodiment of the present invention.
Fig. 2 is that the safety interlocking key control of the embodiment of the present invention is related to schematic diagram.
In figure, be labeled as: motor-car key A in 1-storehouse, 2-mechanical interlocks, 3-converter cabinet key B, 4-auxiliary tank key B.
The specific embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, motor-car safety interlocking control method in the electric power machine garage of the present embodiment, is provided with motor-car key A in storehouse, converter cabinet key and auxiliary tank key B mechanical interlocking device.
Key A: key A inserts mechanical interlocking device, and rotate to " locking " position, key B could be rotated to " release " position by " locking " position, and can extract; Only have 2 key B all in mechanical interlocking device place, and by " release " bit recovery to " locking " position, could operate key A by " locking " bit recovery to " release ", and can extract;
Key B: can release converter cabinet, the cabinet door of auxiliary tank, when inserting key B, and rotation is to " locking " position, and cabinet door can be opened, and now key B can only, in cabinet door place, can not extract; Only close cabinet door, key B could be rotated to " release " position by " locking " position, and extracts;
Locomotive control microcomputer is after obtaining driver controller control command, to detect motor-car key switch state in storehouse, if it is released state in closure, locomotive control microcomputer is closed by control contactor KM1, after KM1 closure, will provide electric energy to converter cabinet, and will be to locomotive control microcomputer feedback closure state signal; Locomotive control microcomputer, after obtaining contactless switch KM1 closure state signal, sends torque command to converter cabinet, and converter cabinet, by out-put supply, drives traction electric machine; Otherwise, keep the off-state of motor-car contactless switch KM1 in storehouse, and report to the police.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
