Abstract
The utility model discloses a long -range reset circuit of locomotive protection device, including protection device and reset button, reset button includes front end reset button RUB1 and rear end reset button RUB2, the parallelly connected back one end of front end reset button RUB1 and rear end reset button RUB2 link to each other with the unblock signal, the other end is established ties with protection device, the unblock signal be 110V+, protection device be major loop earth fault relay MGR, major loop overcurrent relay MOCR, direct current auxiliary power generation overvoltage relay COVR. Adopt this long -range reset circuit, can realize the protection device action remote unblock in back when the locomotive circuit returns to normal. Reduces the labor intensity of stuff, improve work efficiency, increased staff's security simultaneously, made the staff can not touch electric equipment compartment inner zone electric installation because of the mistake and take place the incident, guaranteed the locomotive steady operation.
Description
Technical field
The utility model relates to locomotive protective circuit field, is specifically related to a kind of locomotive protective device remote reset circuit.
Background technology
CKD8G type locomotive is configured with the protective devices such as major loop ground relay, major loop overcurrent relay and direct current auxiliary power generation overvoltage relay; for in locomotive main loop ground protection circuit, circuit overcurrent protection and control protection electric circuit; be used to monitoring locomotive and whether there occurs major loop ground, overcurrent or superpotential situation; and make protection act in the respective cases, send warning to driver simultaneously.Automatically lock after protective device generation protection act, require that staff must enter electric equipment compartment, the corresponding protective device of manual unlocking could restore its defencive function again.Electric equipment compartment charging equipment is numerous, and narrow space, staff is easy to occur to touch by mistake, can cause security incident.Operate also inconvenient simultaneously.
Summary of the invention
The utility model provides a kind of locomotive protective device remote reset circuit, just when locomotive circuit recovers normal, can unlock at a distance after realizing protective device action.
The technical scheme that the utility model adopts is locomotive protective device remote reset circuit; comprise protective device and reset button; reset button comprises front end reset button RUB1 and rear end reset button RUB2; described front end reset button RUB1 is connected with unlocking signal with one end after the reset button RUB2 parallel connection of rear end; the other end is connected with protective device; described unlocking signal is 110V+, and described protective device is major loop ground relay MGR, major loop overcurrent relay MOCR, direct current auxiliary power generation overvoltage relay COVR.
Described reset button is separately positioned on the cab control stand of locomotive two ends.
The beneficial effects of the utility model are: adopt this remote reset circuit, when locomotive circuit recovers normal, can unlock at a distance after realizing protective device action.Alleviate the labour intensity of staff, improve operating efficiency, add the fail safe of staff simultaneously, make staff because encountering charging equipment in electric equipment compartment by mistake, security incident can not occur, ensure locomotive stable operation.
Accompanying drawing explanation
Fig. 1 is locomotive protective device remote reset circuit diagram.
Mark in figure: RUB1-front end remote reset button, RUB2-rear end remote reset button, MGR-major loop ground relay, MOCR-major loop overcurrent relay, COVR-direct current auxiliary power generation overvoltage relay.
Embodiment
Now 1 pair of the utility model is further described by reference to the accompanying drawings, and locomotive two ends cab control stand arranges a remote reset button respectively, front end remote reset button RUB1 and rear end remote reset button RUB2.Protective device comprises major loop ground relay MGR, major loop overcurrent relay MOCR, direct current auxiliary power generation overvoltage relay COVR, after protective device detects locomotive circuit ground connection, overcurrent or overvoltage, and protective device action self-locking.When after detection electric current or voltage resume normal value; namely locomotive control recovers normally; press this remote reset button; front end remote reset button RUB1 or rear end remote reset button RUB2; namely remote de-locking signal (110V+) is applied to protective device; protective device unlocks, and unlocks at a distance after realizing protective device action.When unclamping this remote reset button, when namely stopping applying remote de-locking signal to protective device, protective device recovers its defencive function.This design improves the operating efficiency of driver and conductor, avoids the generation of security incident, effectively ensure that normal, the stable operation of locomotive.
Claims (2)
