Abstract
The invention discloses a varistor or a discharge tube with a temperature protection function. A line input electrode of the varistor or the discharge tube is connected in series with a temperature protector. The varistor or the discharge tube has the following working flow that when the varistor or the discharge tube discharges or is degraded, the temperature can be abnormally risen; when the temperature reaches a threshold value of the temperature protector, the temperature protector switches off a circuit and simultaneously sends a lightning arrester working state signal to a control center; and in the control center, related personnel is arranged to check. Application of the varistor or the discharge tube is suitable for various lightning arresters, surge protectors and railway signal boxes. The product has the advantages that 1, energy is saved, i.e., when the varistor or the discharge tube is degraded, a large leakage current can be generated and if the circuit is not switched off, electricity can be continuously leaked out until the varistor or the discharge tube is completely damaged; and 2, a fire is prevented, i.e., when the varistor or the discharge tube is degraded, the temperature is continuously risen and if inflammables are placed near the installation position of the varistor or the discharge tube, the fire is very easy to occur.
Description
Technical field
The present invention relates to a kind of piezo-resistance with temperature protection or discharge tube.
Background technology
When the piezo-resistance of present stage and discharge tube regular picture, temperature can raise unusually, can affect the stability of whole system.The present invention can effectively address the above problem.
Summary of the invention
Technical problem to be solved by this invention is: a kind of piezo-resistance with temperature protection or discharge tube are provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of piezo-resistance or discharge tube with temperature protection are at temperature protector of circuit input electrode serial connection of piezo-resistance or discharge tube.
Workflow is: when the discharge of piezo-resistance and discharge tube or when deteriorated; temperature can raise unusually, when reaching the threshold values of temperature protector, and the temperature protector open-circuit line; send the lightning protection device working state signal to control centre simultaneously, control centre arranges the related personnel to check.
Purposes of the present invention is fit to various lightning protection devices, Surge Protector, railway signal box.
The product advantage is: 1, energy-conservation.When piezo-resistance and discharge tube are deteriorated, can produce larger leakage current, if open-circuit line not, it can continue electric leakage, until thoroughly damage.2, prevent the generation of fire.When piezo-resistance and discharge tube were deteriorated, temperature continued to raise, if combustibles, fire are arranged near the installation site.
