Abstract
The utility model discloses an automatic power failure and supply device of an overhead line of a trolley locomotive, comprising a shell, wherein the shell is provided with four terminals A, B, C and D, and internally provided with an automatic power failure and supply circuit of the overhead line; the circuit is provided with a direct-current power supply U lower than safe voltage; a negative terminal of the direct-current power supply U is divided into two branches which are connected with the terminals C and D respectively; a positive terminal of the direct-current power supply U is sequentially and serially connected with a divider resistor 2R, a current-limiting resistor 1R and a clamping diode D, and then connected with the terminal B; the device also comprises a current transformer FL, a line switch K and a PLC programmable controller; one end of the current transformer FL is connected with the terminal A, and the other end is serially connected with the line switch K and then connected with the terminal B; a signal end of the current transformer FL and a signal end of the divider resistor 2R are connected with input ends of the PLC programmable controller respectively; and an output end of the PLC programmable controller is connected with a control end of the line switch K. The device effectively solves the automatic power failure and supply problem of the overhead line of the trolley locomotive, and can greatly shorten the energized time of the overhead line, thus greatly reducing the probability of electrical shock injuries of underground workers.
Description
Technical field: the utility model belongs to the electrical equipment technology, particularly relates to a kind of automatic transmission or not device of road transportation system stringing electrical locomotive pole line that is used for.
Background technology: because stringing electrical locomotive has simple, sturdy and durable, easy to maintenance, the free of contamination characteristics of system, China all adopts in most of mines the main means of transport of dc electric electric locomotive under driving a well as the ore deposit.Pole line mostly adopts the long-time continuous power supply at present, long playing mode, and overhead transmission line voltage is higher, is generally more than the direct current 250V.But because the mine underworkings is narrow, limited space, there was dampness in the air, personnel and locomotive are gone together in same tunnel, very easily cause personnel's electric shock casualty accident, particularly when the loading and unloading operation of exploiting field, the probability of touching pole line generation electric shock is higher, often causes personnel death's major accident.For this reason, shorten the time of pole line charging operation as far as possible, make pole line only charged when electric locomotive moves, electric locomotive does not have electricity when stopping transport, and is the important safety measure that reduces electric shock accidents.
Summary of the invention: the purpose of this utility model provides the automatic transmission or not device of a kind of stringing electrical locomotive pole line, in order to effective solution existing in prior technology the problems referred to above.The purpose of this utility model realizes with following technical scheme: it has a housing, housing is provided with four binding posts, be respectively A, B, C and D, the automatic transmission or not circuit of pole line is installed in the housing, this circuit has a direct supply U who is lower than safe voltage, and the negative terminal of direct supply U is divided into two, is connected with D with binding post C respectively, after anode was connected in series divider resistance 2R, current-limiting resistance 1R and catching diode D successively, B was connected with binding post; It also has a current transducer FL, line switching K and a PLC programming controller, the end of current transducer FL is connected with binding post A, after the other end tandem link K switch, connect binding post B, the signal end of the signal end of current transducer FL and divider resistance 2R respectively is connected an input end of PLC programming controller, the control end of the output terminal connection line K switch of PLC programming controller.
During use, device of the present utility model is installed on the top that desire is controlled automatic transmission or not pole line highway section, binding post A, B are serially connected with in the pole line 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 is judged by analysis, assert that electric locomotive does not rerun, and just exports power cut signal, the operation circuit K switch disconnects and having a power failure, thereby realizes that pole line has a power failure; The direct supply U that be lower than safe voltage this moment sends into overhead transmission line, no-load running by divider resistance 2R, current-limiting resistance 1R and catching diode D.At this moment, divider resistance 2R no signal output.When electric locomotive needs to drive, when the driver connects the electric locomotive electric loop by control switch, promptly form the loop, at this moment, divider resistance 2R just has signal output, and deliver to the PLC programming controller, the PLC programming controller is judged by analysis, confirms electric locomotive request operation, then send and send electric signal to line switching K, line switching K connects, thereby realizes sending electricity to pole line, and electric locomotive just brings into operation.At this moment, because the clamped effect of catching diode D, divider resistance 2R goes up no current and flows through, no signal output.Because the operation of electric locomotive has electric current to flow through on the current transducer FL, signal output is arranged just simultaneously.
The utility model is novel, circuit design is simple, reasonable, effectively solve the automatic transmission or not problem of stringing electrical locomotive overhead transmission line, can shorten the electrification time of overhead transmission line greatly, thereby significantly reduced the get an electric shock probability of casualty accident of underground work personnel.
