Abstract
The invention discloses an intelligent safe power supply for electric locomotive overhead lines. The intelligent safe power supply comprises a shell, wherein the shell is provided with four wiring terminals, respectively, A, B, C and D; an automatic overhead line stop-supply circuit is mounted in the shell, and the circuit has a direct-current source U of which voltage is lower than the safe voltage; a cathode of the direct-current source U is connected between the wiring terminal C and the wiring terminal D, and an anode of the direct-current source U is connected in series with a low current detector L1 and a leakage current detector L2 in sequence and then is connected with the wiring terminal B; and the circuit further comprises a current transducer FL, a line switch K and a PLC (Programmable Logic Controller), wherein the output ends of the low current detector L1 and the leakage current detector L2 are respectively connected with the input end of the PLC. By adoption of the technical scheme, long-term power supply of the overhead lines can be changed into short-time power supply, namely, the power is only supplied for an electric locomotive operating section, and other overhead lines are all in power failure state; specially, a leakage current detection circuit is provided, thereby avoiding the phenomenon that the PLC sends a power supply instruction again to supply power by mistake in case of electric leakage, and further guaranteeing the safety of people walking under the overhead lines, and reducing personal electric shock accidents.
Description
Technical field
The present invention relates to a kind of mine electrical installation, especially relate to a kind of mine electric vehicle overheading line intelligence transmission or not device.
Background technology
At present, the electric locomotive down-hole air wire that China uses in the mine generally adopts the subregion insulation, promptly utilizes zoning switch to be electrically connected, and also has indivedual mines to install travel switch in the parking lot and fixes a point to cut off the power supply.These methods all belong to the interim of short duration power failure in the parking lot, and air wire is always charged for a long time, and aerial line voltage is generally higher, is easy to occur electric shock accidents.The measure that realizes above-mentioned operation scheme almost is the operating mode with artificial deciliter power on-off device or zoning switch, carry out people parking lot and the passing frequent section of personnel stop send electricity or divide the section power failure to give.Though this mode is reliable,, also brought the hidden danger that causes owing to this operation simultaneously far away on response time and work efficiency because manual operation can not meet the demands.Chinese patent discloses a kind of " the automatic transmission or not device of stringing electrical locomotive air wire ", though this power on-off device has realized making air wire only charged when electric locomotive moves, electric locomotive does not have when stopping transport; Shortened the time of air wire charging operation; But also there is following problem, promptly during low voltage power supply, in case when electric leakage or little electric current leak; Can make PLC assign the power supply instruction once more and cause the misdelivery electricity, cause safety misadventure more easily.
Summary of the invention
The purpose of this invention is to provide a kind of detection of electrical leakage circuit that has; Safe and reliable intelligent electric locomotive air wire transmission or not device; Change the long-term power supply of air wire into sectional type and supply power in short-term, promptly only to the power supply of electric locomotive target phase, and other air wire all is in off-position; Thereby walker person's safety under the assurance air wire reduces the accident of human electric shock.
The objective of the invention is to realize through following technical scheme; It has a housing, and housing is provided with four binding posts, is respectively A, B, C, D; The automatic transmission or not circuit of air wire is installed in the housing; This circuit have one be lower than safety voltage direct supply U, the negative pole of direct supply U is connected between binding post C and the D, positive pole is connected in series little current probe L successively
1, leakage current detector L
2After, B is connected with binding post; It also has a current transducer FL, line breaker K and a PLC programming controller; The end of current transducer FL is connected with binding post B; After the other end tandem link K switch, connect binding post A, the signal end of current transducer FL connects an input end of PLC programming controller; The control end of the mouth connection line K switch of PLC programming controller, little current probe L
1, leakage current detector L
2Mouth is connected with the input end of PLC programming controller respectively.
During use, device of the present invention is installed on the top that desire is controlled automatic transmission or not air wire highway section, binding post A, B are serially connected with in the air wire supply line, binding post C, D are serially connected with in the track reflux line and get final product.After electric locomotive stopped, current transducer FL dead electricity was delivered to the PLC programming controller with this dead electricity signal; The PLC programming controller assert that through analysis and judgement electric locomotive does not rerun, and just exports power cut signal; The control path K switch is broken off and being had a power failure; Thereby realize that air wire has a power failure, at this moment, the direct supply U that is lower than safety voltage is through little current probe L
1, leakage current detector L
2Send into aerial line, no-load run.At this moment, L
1, L
2Do not have and send electric current.When electric locomotive needs to drive, when the driver connects the electric locomotive electric loop through control switch, promptly form the loop, at this moment, L
1, L
2Just send electric current signal output, and deliver to the PLC programming controller, the PLC programming controller is through analysis and judgement; Confirm electric locomotive request power supply, then send and send electric signal that line breaker K connects to line breaker K; Thereby realize sending electricity to air wire, electric locomotive just brings into operation, when the line electrical leakage of output; Leakage indicator is assigned the instruction of stopping power supply and is given PLC programming controller, the transmission operation of PLC programming controller halt switch K.
Beneficial effect of the present invention: owing to adopt technique scheme; Can change the long-term power supply of air wire into sectional type and supply power in short-term, promptly only to the power supply of electric locomotive target phase, and other air wire all is in off-position; Particularly be provided with electric-leakage detection circuit; Prevented to cause the misdelivery electricity, thereby guaranteed walker person's under the air wire safety, reduced the accident of human electric shock because of electric leakage makes PLC assign the power supply instruction once more.
