Description
Technical field
The utility model is related to the technical fields of sensing element, particularly a kind of bus joint device temperature sensor.
Background technology
Thermistor is a kind of thermally sensitive semiconductor ceramic element, have reaction is fast, precision is high, stability is good,
The characteristics of at low cost, is widely used in all kinds of occasions related with temperature.Particularly fire protection sector is directly linked up with temperature, electrically
80% Producing reason is in fire：Overload fire and contact resistance cross conflagration.
When conducting wire overload, wire insulation aged deterioration is accelerated.When serious overload, the temperature of conducting wire can not
It is disconnected to raise or even the insulation of conducting wire be caused to burn, and the combustible near energy ignition leads, so as to cause fire.And
Contact resistance crosses the place of the every conducting wire of conflagration and the connections such as conducting wire, conducting wire and switch, fuse, instrument, electrical equipment all
There is connector, the resistance formed on the contact surface of connector is known as contact resistance.If there is impurity in connector, connection it is not firm or its
His reason makes junction contacts bad, and the local electrical resistance for causing contact site is excessive, when electric current passes through connector, will produce here
Raw substantial amounts of heat, forms high temperature, this phenomenon is exactly that contact resistance is excessive.Have larger current by electric wiring on, such as
When contact resistance excessive this phenomenon somewhere occurs in fruit, greatly heat will be generated in the excessive subrange of contact resistance
Amount makes metal discoloration even melt, the insulating layer of conducting wire is caused to burn, and product on ignite combustible or conducting wire near burning
Dust, fiber for falling etc., so as to cause fire.
Temperature sensor is for its basic principle of fire alarm, when the parameters such as electric current, the temperature in electrical equipment are sent out
During raw abnormal or mutation, end-probing head (such as residual current transformer, temperature sensor) utilizes electromagnetic field inducing principle, temperature
The variation of degree effect is acquired the information, and is transported in monitoring detector, through amplification, A/D conversions, CPU to variation
Amplitude is analyzed and judged, and compared with alarm setting value, alarm signal is sent if beyond setting value, while
It is transported in monitoring device, then further identifies and judge through monitoring device.When may fire occur for confirmation, monitoring host computer
Fire alarm signal is sent, lights alarm lamp, sends alarm sound, while in liquid crystal display screen display fire alarm etc.
Information, the information that operator on duty then shows according to display screen carry out inspection processing to the scene of the accident rapidly, and warning message are sent out
It is sent to integrated console.
The existing temperature sensor for fire alarm, dimensional structure is fixed, without General adaptive.
Utility model content
In view of this, the main purpose of the utility model is that providing that a kind of thermometric is accurate, is easily installed, suitable for various
