Abstract
The utility model provides a special intelligent circuit breaker for railways, which comprises a handcart, a circuit breaker body, an intelligent operating device, an intelligent temperature adjusting device, a position sensor, an electronic current transformer and a vacuum degree monitoring device. The circuit breaker body is arranged on the handcart, the intelligent operating device arranged on the handcart is electrically connected with the circuit breaker body, the intelligent temperature adjusting device, the position sensor and the electronic current transformer are electrically connected with the intelligent operating device, and the vacuum degree monitoring device is mounted on the handcart. The special intelligent circuit breaker for railways can monitor working state of a circuit breaker in real time, automatically adjusts to adapt to some state changes such as environment temperature and the like, exchanges information with a backstage of a control room in case of detecting failure condition for judgment of the control room so as to employ selective tripping in a remote-control manner, and is mainly used as a railway line such as an electrified railway traction transformer substation, a switching station, a section post and the like for traction of a power supply system to receive and distribute electric energy.
Description
Technical field
The utility model relates to a kind of electric equipment, particularly relates to a kind of railway special intelligent circuit breaker.
Background technology
Railway definite purpose circuit breaker used in the railway track tractive power supply system comprises handcart, is arranged on the breaker body on the handcart, is installed in the electromagnetic current transducer that is connected with breaker body on the handcart.This kind electromagnetic current transducer is because magnetically saturated restriction, and versatility is poor, measures and defencive function need separate, thereby causes the instrument transformer volume bigger, and its insulation property are difficult for satisfying, and the dried ability of scratching of anti-electromagnetism also a little less than.Can not monitor in real time circuit breaker on the other hand, can not rationally effectively control and safeguard circuit breaker, the self adaptation in can not realizing operating cooperates, and must rely on the control system of transformer station's level, based on the limitation of above technology, restricted the intelligent development of circuit breaker.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of intelligent degree height is provided, and is simple to operate, the railway special intelligent circuit breaker that reliability is high.
The utility model railway special intelligent circuit breaker comprises handcart, be arranged on the breaker body on the handcart, be arranged on the handcart with breaker body have electric connecting relation intelligent actuation means, with intelligent actuation means intelligent thermoregulating device, position transducer and the electronic current mutual inductor of electric connecting relation are arranged, and be installed in the vacuum-degree monitoring device on the handcart.
The operation principle of the utility model railway special intelligent circuit breaker is; during operate as normal; handcart is in the service position; circuit breaker is in "on" position; position transducer passes to intelligent actuation means with this position state signal; electronic current mutual inductor is monitored the circuit breaker main circuit current; offering intelligent actuation means is used for calculating and protection; the intelligent thermoregulating device is monitored the residing ambient temperature of circuit breaker; and real-time Transmission is given intelligent actuation means; when ambient temperature is crossed when low; the heating element that the intelligent thermoregulating device starts on it heats up to circuit breaker; when ambient temperature is too high; the blower fan element that the intelligent thermoregulating device starts on it is lowered the temperature to circuit breaker; the vacuum-degree monitoring device is implemented monitoring to the vacuum degree of breaker body; and give intelligent actuation means with message transmission; the Operation and Maintenance personnel can check the various state informations of current circuit breaker on its man-machine interface; when circuit-breaker status is unusual; when being lower than standard value as vacuum degree; the vacuum-degree monitoring device is reported to the police; the intelligence actuation means starts breaker open operation, so that circuit breaker is safeguarded and changed.Intelligent actuation means can also be with the man-machine work station in working state of circuit breaker information uploading backstage simultaneously, when electronic current mutual inductor monitors when having short circuit current to flow through in the circuit breaker major loop, after this information passes to the man-machine work station in backstage, man-machine work station is through to circuit breaker integrated information analysis and judgement at different levels, determines remote control respective circuit breakers separating brake behind the fault coverage.
The advantage of the utility model railway special intelligent circuit breaker is to adopt exportable low pressure analog quantity of electronic current mutual inductor and digital quantity signal; be directly used in Microcomputer Protection and electronic type measuring equipment; adapt to electronic system digitlization, intellectuality and networked needs; its dynamic range is big; can simultaneous adaptation measure and protect two kinds of functions, and have the dried ability of scratching of good, the anti-electromagnetism of insulation property and reach characteristics such as measuring bandwidth more by force.Installing intelligent actuation means, intelligent thermoregulating device, position transducer and vacuum-degree monitoring device on the handcart additional can monitor in real time to working state of circuit breaker, at some state variation, carrying out self adaptation as ambient temperature etc. regulates, and after monitoring failure condition, carry out information interchange with the backstage, control room, judge for the control room, the selectivity tripping operation is implemented in control far away.Mainly make in electric railway traction electric substation, switching station, subregion booth etc. and accept and distribute the usefulness of electric energy as the railway track tractive power supply system.
