[specific embodiment]
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure and principle of this device people professional to this
For be very clearly.It should be appreciated that specific embodiment described herein is only to explain this utility model, and without
In restriction this utility model.
This utility model is a kind of intelligent breaker busbar temperature detection means, by temperature measuring probe is embedded in electric current
Transformer is installed in the middle of the ad-hoc location of housing, and fixing temperature by way of high temperature resistant adhesive plaster winds current mutual inductor coil
Degree detection probe, the model of temperature measuring probe are preferably PT100 temperature probes.
As shown in figure 1, installing under housing frame mode existing current transformer is not changed, need PT100 temperature
In the embedded transformer mounting shell body of detection probe, as shown in Figure 1.By PT100 temperature measuring probes, according to the direction of Fig. 1 positions
Lay, wire is then wrapped on mutual inductor coil with high temperature resistant adhesive plaster, reaches the purpose of fixed PT100 temperature measuring probes.
Adhesive plaster may only be wrapped in lead location, can not be wound into detection probe position, in order to avoid affect the performance of measurement temperature probe.Such as
It is in need, it is also possible to after the same method, PT100 temperature measuring probes are positioned under another mutual inductor coil position.
As shown in Fig. 2 be current transformer bonnet figure, by PT100 temperature measuring probes embedded current transformer mounting shell
After in body, bonnet is locked, i.e., this temperature-detecting device is laid and finished.
Current transformer practice is enclosed within intelligent breaker busbar, when busbar adstante febre, due to current transformer
Connect with being close to during busbar, thus the temperature of busbar can pass through air and contact transmission on current transformer, band streaming current is mutual
Sensor generates heat.At this moment the PT100 temperature measuring probes that current transformer is installed in housing are embedded in, can be generated heat according to current transformer
And oneself resistance of itself is changed, by shielding line, the resistance of oneself is sent to into control system.The utility model can be simultaneously
Measurement multichannel busbar temperature, only needs the embedded current transformer of practical multiple band PT100 temperature measuring probes to install in housing.
