Description
Technical field
The utility model is related to power domain, and in particular to a kind of isolation switch contact temperature real-time monitoring device.
Background technology
Open isolating switch is placed on outdoor in high voltage substation, after repeatedly cut-offfing, due to vibration, mechanical deformation, ring
The influence of the factors such as border, contact resistance increases between causing contact, in turn results in the huge increasing of caloric value, if taken no action to, contact
Abnormal heating continues, and eventually causes disconnecting switch to be burnt, and even results in the danger for expanding power grid accident.Conventional method is to stop
D.C. resistance experiment is done by testing crew when electric, or every isolated by staff's carrying infrared measurement of temperature equipment in operation
Switch is detected.
Existing technology is to carry out real time on-line monitoring to isolation switch contact using infrared temperature-test technology.Infrared measurement of temperature is set
It is standby to be placed on disconnecting switch Steel Structure.Insulation column porcelain knob is used to chopper switch is play a part of to support and insulated.Due to knife
Lock switch ends connect high-voltage conducting wires, therefore whole chopper switch band high voltage.When the contact of chopper switch is bad, contact
It can generate heat, while infrared ray can outwards be discharged, temperature is higher, and the infra-red intensity of release is bigger, be placed on the infrared survey of lower end
Warm equipment judges the size of contact temperature by the ultrared power received, and by the way that wirelessly temperature value is sent to after
Platform monitors main frame.Infrared measurement of temperature monitoring device has the following disadvantages：1) need low pressure inlet wire to power, therefore additionally to arrange power supply
Line, adds the time of equipment cost and construction；2) contact position of high voltage isolator is all very high, it is difficult to judge infrared measurement of temperature
Whether head targeted by the contact of disconnecting switch, while high voltage isolator is mounted in open air, blows, touches by mistake, switching machinery and shake
The factor such as dynamic easily causes the skew of infrared temperature measuring head position；3) outdoor different weather influences very on the accuracy of infrared measurement of temperature
Greatly, in addition, the long dust of time one can fall on infrared temperature measuring head, hinder to cause ultrared transmission the error of measurement.
In addition, monitoring device is typically all to be directly mounted on switch contact, if therefore monitoring device does not use heat-insulated
Material, can absorb the heat on switch contact, and substantially temperature transmission is inaccurate, and each position on switch contact is by outside
The influence of ambient influnence, such as cooling system, the real time temperature at each position is discrepant, therefore in the prior art only with
The monitoring of position just represents the monitoring of whole switch contact at one, and its data is not exclusively correct.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of small, easy for installation, general by external environment influence
Property it is strong, monitor more accurate isolation switch contact temperature real-time monitoring device.
The utility model is achieved through the following technical solutions：A kind of isolation switch contact temperature monitors dress in real time
Put, including the temperature measuring equipment that is installed on switch contact and the monitor box for receiving temperature measuring equipment temperature measurement data, it is described
Temperature measuring equipment includes a geometrical clamp, and the two ends of the geometrical clamp set a hook portion respectively；
A V-type linkage section is provided between hook portion and geometrical clamp, the hook portion and geometrical clamp medial surface are respectively arranged with
More than one thermistor, one end and the side contacts of switch contact one of the thermistor, the other end sets a silica gel backing plate,
The signal output part connection monitor box of thermistor, monitor box receives temperature signal and transmitted by internal wireless transmitter module
To remote control center.
As preferred technical scheme, a signal processing circuit is installed in the monitor box, the monitor box passes through it
Internal storage battery power supply, battery is respectively that signal processing circuit and wireless transmitter module are powered by power line.
As preferred technical scheme, geometrical clamp is internally provided with wiring channel, and thermistor is connected through signal transmssion line
Signal processing circuit, signal transmssion line is arranged in wiring channel.
It is used as preferred technical scheme, the layer insulating of geometrical clamp outer wrap one.
As preferred technical scheme, the monitor box uses polytetrafluoroethylene (PTFE) shell.
The beneficial effects of the utility model are：The utility model can carry out supervising simultaneously to multiple positions of switch contact
Survey, it is ensured that the uniform monitoring to switch contact, whole device is separated in switch contact completely, therefore monitoring device is not interfered with out
The temperature of contact is closed, and whole detection means installs very convenient.
