Abstract
The utility model provides an ideal temperature measurement controller of a relay protection cabinet, which belongs to the technical field of accessories of power station protection devices. The temperature measurement controller is mainly characterized by comprising a temperature monitoring circuit, a signal judging circuit, an air conditioner control circuit, and an alarming circuit; when the temperature rises to a preset alarm setting value, an alarm normally-open contact of an intelligent relay is closed, an output loop transmits the data to an alarm circuit, and when the temperature reaches the preset alarm setting value, the alarm normally-open contact of the intelligent relay is closed, the output loop transmits the data to the alarm circuit and then the alarm circuit transmits the signal to a duty room of a power station, and thus relevant personnel takes emergency measures as soon as possible to prevent accident from further deterioration and ensure safety operation of the device. Compared with the prior art, when the temperature in the cabinet is high, the relevant personnel in the duty room of the power station can timely find out and process the situation, the accident is avoided, and the normal and safe operation of the equipment is ensured.
Description
Technical field
The utility model relates to transforming plant protecting device attachment technique field, is specifically related to a kind of relay protection cabinet temperature measurement controller.
Background technology
The relay protection cabinet is to be combined by protective relaying device, support equipment and auxiliary element; existing relay protection cabinet protective device can cause the contact heating because of the load increase; directly influence relay protector and normally move, operation causes a hidden trouble to power equipment safety.Therefore existing relay protection cabinet exists temperature when too high, and the duty room personnel can't know, are prone to accidents, and influence the deficiencies such as normal operation of equipment.
The utility model content
The purpose of this utility model is a kind of relay protection cabinet temperature measurement controller of design, normally moves in order to non-electricity protector, guarantees to solve the hidden danger of power equipment existence in service.
For reaching above-mentioned purpose; technical solution adopted in the utility model is; this relay protection cabinet temperature measurement controller; it is characterized in that: comprise temperature observation circuit, signal judging circuit, air conditioner control circuit and warning circuit; described temperature observation circuit outputs signal to signal judging circuit, and described signal judging circuit is controlled described air conditioner control circuit and warning circuit respectively.
Described temperature observation circuit is made up of temperature monitoring, output loop, and temperature monitoring is directly installed in the relay protection cabinet, realizes the temperature of on-line monitoring secondary electric contact, and by output loop temperature data is sent to signal judging circuit.
Described signal judging circuit, formed by parameter decision circuitry, intelligent relay, output loop, after temperature data is sent to the parameter decision circuitry, the parameter decision circuitry is according to the measurement range comparison that sets in advance, temperature reaches when starting the air conditioner setting valve, intelligent relay normally opened contact closure, output loop is sent to the air conditioner control circuit with data, and control circuit starts the air conditioner cooling; When temperature be reduced to setting close the air conditioner temperature time, the intelligent relay normally opened contact disconnects, air conditioner stops.If temperature continues to rise, when arriving the warning setting valve of setting, intelligent relay warning normally opened contact closure, output loop is sent to warning circuit with data, warning circuit passes the signal along to transformer station's duty room and reports to the police, the relevant personnel are taken emergency measures as early as possible, avoid accident further to enlarge, guarantee equipment safety operation.
The utility model provides a kind of desirable relay protection cabinet temperature measurement controller for power station protection equipment appurtenance technical field.Its principal feature is; Comprise temperature observation circuit, signal judging circuit, air conditioner control circuit, warning circuit; Because temperature monitoring is directly installed in the relay protection cabinet, realizes the temperature of on-line monitoring secondary electric contact, and by output loop temperature data is sent to signal judging circuit; After temperature data is sent to the parameter decision circuitry, the parameter decision circuitry is according to the measurement range comparison that sets in advance, and temperature reaches when starting the air conditioner setting valve, intelligent relay normally opened contact closure, output loop is sent to the air conditioner control circuit with data, and control circuit starts the air conditioner cooling; When temperature be reduced to setting close the air conditioner temperature time, the intelligent relay normally opened contact disconnects, air conditioner stops.If temperature continues to rise, when arriving the warning setting valve of setting, intelligent relay warning normally opened contact closure, output loop is sent to warning circuit with data, warning circuit passes the signal along to transformer station's duty room and reports to the police, the relevant personnel are taken emergency measures as early as possible, avoid accident further to enlarge, guarantee equipment safety operation.Compared with prior art have; The staff of power transformation duty room can in time find and handle when in-cabinet temperature was high, avoided the generation of accident, can guarantee the remarkable advantages such as normal safe operation of equipment.
