And any restriction applied or use.
From the point of view of electrochemical capacitor material behavior and use experience, the ageing process of the big capacity electrolyte capacitor in UPS equipment
It is usually associated with the internal temperature uphill process of electrochemical capacitor, say, that the change of electric capacity internal temperature is capacitance variations
One key signal, after electric capacity internal temperature raises, heat just increases, and heat of long duration can be delivered to capacitance shell, causes
The rising of capacitance shell temperature, certainly, internal and external temperature has slight gap, forms a thermograde, but the two difference is very
Little, therefore, it can use for reference the temperature of electric capacity outer surface to reflect the temperature within electric capacity.According to measured UPS equipment work
Under state, the hull-skin temperature of electrochemical capacitor is it may determine that go out whether electric capacity occurs in that exception.There is temperature anomaly in electric capacity

Under show different resistance values.Positive temperature coefficient thermistor resistance value when temperature is the highest is the biggest, negative temperature coefficient heat
Sensitive resistor resistance value when temperature is the highest is the lowest.Further, this critesistor can be semistor or
Negative tempperature coefficient thermistor, critesistor becomes non-linear relation with temperature, and during room temperature, resistance variations is the least, temperature liter during high temperature
High 1 degree, resistance value can increase doublely.
Further, the temperature measurement range of linear temperature sensor probe is at least not less than 0～150 degree, and in temperature
Degree presents linear relationship in the range of measuring between resistance value and temperature value, corresponding to accurately determine out it according to resistance value
Temperature value.
It addition, the distance of the linear temperature sensor probe being arranged in electric capacity surrounding air and each electric capacity can be between 10
Centimetre and 15 centimetres between, if this probe is too near to electric capacity, can be disturbed by the surface temperature of electric capacity, again can not too remotely from electric capacity
Represent the true environment situation of capacitor regions.Visible, if too small with the distance of electric capacity or excessive all can not accurately measure electricity
Hold the temperature of surrounding air.
For the ease of monitoring with safeguard, outside UPS cabinet, by that draw with each temperature sensor from UPS cabinet inside
The cable that probe is connected is integrated into the plug receptacle of a standard, is conveniently connected to other by the plug receptacle of this standard
On equipment or instrument.Wherein, temperature alarm is permanently connected with the plug receptacle of standard by resistance temperature harvester, to send out in time
Existing alert.Display can be permanently connected with temperature measurement circuit or connect when carrying out temperature monitoring by resistance temperature harvester again
Connect.When the changing condition of each capacitance temperature in alert occurs or attendant needs periodic logging UPS, this interface can be led to
Cross resistance temperature harvester to be connected on display with temperature measurement circuit.
