Description

Secondary current loop of transforming plant state on_line monitoring system
Technical field
The utility model relates to transformer substation foundation apparatus field, particularly a kind of secondary current loop of transforming plant state on_line monitoring system.
Background technology
Whole electric system is that once system and electrical secondary system are formed, and only has this two system reliability services, the safe and reliable operation of the whole electric system of guarantee; But nowadays, in the construction and maintenance of electric substation, focus on primary system, ignore the situation of electrical secondary system.
There is a large amount of secondary current connection circuits in each electric substation, this current return is that whole current system is carried out measuring, protects, dispatched, the basis of monitoring etc.But because this loop exists a large amount of connection terminals; and loop current is larger; often occur that wiring place is burnt, blow, the fault such as damage; thus have influence on the normal operation of the part such as measurement, protection, scheduling of whole electric substation, great hidden danger is brought to the safety of whole electrical network, reliability service.Meanwhile, current transformer also may be caused when contact damages to open a way, produce effluve, even puncture electric elements, cause equipment breakdown; Cause large-scale power-off or cause fire.
Owing to having every year because secondary current loop fault causes the generation of false protection and tripping accident, each electric company all strengthens tour to secondary circuit and maintenance.But at present, whether the monitoring both at home and abroad for electric substation's secondary current loop mainly contains following several method: the method for (1) manual patrol: regular or irregular arrangement personnel utilize the method for range estimation to make an inspection tour to secondary current loop, existed burn and peculiar smell by observation secondary current connection terminal and wire outward appearance; (2) after primary system power failure, electrical secondary system detected and safeguard; (3) utilize the connection terminal temperature of hand-held temperature tester to secondary current loop to measure, thus judge the state in secondary current loop.These methods above-mentioned all have certain meaning to the fault reducing secondary current loop, but these methods all exist, and workload is large, reliability is low, can not prevent the generation of secondary current loop fault in real time.
Utility model content
The purpose of this utility model is to provide that a kind of reliability is high, Real-Time Monitoring and the secondary current loop of transforming plant state on_line monitoring system that can increase work efficiency.
The technical solution realizing the utility model object is:
The utility model secondary current loop of transforming plant state on_line monitoring system, comprises preposition sense terminals, debugging monitoring terminal and power module; Described preposition sense terminals is connected with debugging monitoring terminal, and preposition sense terminals transmits live signal by wireless to debugging monitoring terminal; Power module respectively with preposition sense terminals, debug monitoring terminal and be connected, power module is preposition sense terminals, debugging monitoring terminal is powered; Described preposition sense terminals comprises several temperature sensors, several wave filters, several comparers, several overheated display alarms and overheated voice guard, each temperature sensor connects corresponding wave filter, comparer and overheated display alarm successively, the output terminal of each comparer is connected with overheated voice guard, described debugging monitoring terminal comprises main frame, receives the data that preposition sense terminals sends.
The utility model compared with prior art, its remarkable advantage:
(1) the utility model secondary current loop of transforming plant state on_line monitoring system has the preposition sense terminals that accuracy of detection is high, judge in time reliable, little, the easy installation of volume.
(2) the utility model secondary current loop of transforming plant state on_line monitoring system can realize the secondary current loop of transforming plant status monitoring communication platform of reliable wireless telecommunications in switch cubicle.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
