Abstract
The utility model provides an ideal 10kV metal-clad switch cabinet temperature-measurement heat-dissipation alarm. The 10kV metal-clad switch cabinet temperature-measurement heat-dissipation alarm is characterized in that the 10kV metal-clad switch cabinet temperature-measurement heat-dissipation alarm includes a wireless temperature sensor, a signal judging circuit, a fan control circuit and a wireless alarm transmitting circuit; because a temperature detector of the wireless temperature sensor is directly mounted in a 10kV switch cabinet, the temperature of electric contacts can be acquired; temperature data are transmitted to the signal judging circuit through a wireless transmission loop; and after the temperature data are transmitted to a parameter judging circuit of the signal judging circuit, when the temperature reaches a set alarm setting value, the wireless alarm transmitting circuit can transmit signals to a transformer substation duty room. Compared with the prior art, the 10kV metal-clad switch cabinet temperature-measurement heat-dissipation alarm of the utility model has the following advantage that: when the temperature in the cabinet is high, the staff in the transformer substation duty room can timely find and deal with the situation, such that accidents can be avoided, and the normal safe operation of equipment can be ensured.
Description
Technical field
The utility model belongs to power plant, transformer station transforming plant protecting device attachment technique field, especially relates to a kind of 10kV metal armouring switch cubicle thermometric heat radiation alarm.
Background technology
10kV metal armouring switch cubicle is one of electric equipment important in power plant and the electric substation, and it can switch on and off the electric current in the high-tension circuit under the various situations, in order to change and the quick excision faulty circuit of finishing the main electrical scheme operational mode.Because 10kV metal armouring switch cubicle is hermetic, it is bad to dispel the heat, and especially when high load capacity, the temperature of electric contact reaches 70 degree-90 degree, and high temperature further raises the temperature of electric contact in the switch cubicle, will influence the equipment reliability service like this.Therefore existing 10kV metal armouring switch cubicle exists; The staff of power transformation night shift room can't find and control when in-cabinet temperature was high, was prone to accidents, and normal operation that influences equipment etc. is not enough.
The utility model content
The purpose of this utility model provides a kind of 10kV metal armouring switch cubicle thermometric heat radiation alarm, and when in-cabinet temperature was high, the staff of power transformation night shift room can in time find and handle, and avoided the generation of accident.
For reaching above-mentioned purpose, technical solution adopted in the utility model is, this 10kV metal armouring switch cubicle thermometric heat radiation alarm, it is characterized in that: by radio temperature sensor, signal judging circuit, draught fan control circuit, wireless alarming emissioning circuit constitutes, described radio temperature sensor transmission of electric signals is to signal judging circuit, the described draught fan control circuit of described signal judging circuit control connection and described wireless alarming emissioning circuit.
Described radio temperature sensor is made up of hygrosensor, wireless transmission loop, and hygrosensor is directly installed in the 10kV switch cubicle, gathers the temperature of electric contact, and by the wireless transmission 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 sends to the parameter decision circuitry, the parameter decision circuitry is according to the measuring range comparison that sets in advance, temperature reaches when starting the blower fan setting value, intelligent relay normally opened contact closure, output loop is sent to draught fan control circuit with data, the cooling of control circuit starting switch cabinet inner blower; When temperature be reduced to setting close the blower fan temperature time, the intelligent relay normally opened contact disconnects, the switch cubicle inner blower stops, if temperature continues to rise, when arriving the warning setting value of setting, intelligent relay warning normally opened contact closure, output loop is sent to wireless alarming emissioning circuit with data.
The utility model is the power plant. transforming plant protecting device attachment technique field provides a kind of desirable 10kV metal armouring switch cubicle thermometric heat radiation alarm.Its main feature is, comprise radio temperature sensor, signal judging circuit, draught fan control circuit, wireless alarming emissioning circuit, because the hygrosensor of radio temperature sensor is directly installed in the 10kV switch cubicle, gathers the temperature of electric contact, and by the wireless transmission loop temperature data is sent to signal judging circuit; After temperature data sends to the parameter decision circuitry of signal judging circuit, the parameter decision circuitry is according to the measuring range comparison that sets in advance, temperature reaches when arriving the warning setting value of setting, intelligent relay warning normally opened contact closure, output loop is sent to wireless alarming emissioning circuit with data, and wireless alarming emissioning circuit carries out a distant place and reports to the police.Signal is delivered to transformer station's night shift room, and the relevant personnel are taken emergency measures as early as possible, avoids the accident progress to enlarge, and guarantees equipment safety operation.Compared with prior art have; The staff of power transformation night shift 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.
