What is the difference between a self restoring fuse and a temperature relay? What are the differences? There is a network called "wind uncle" friends to small series of questions to this question. Then, from the electronic technology for the users to answer at the same time also hope that the friends get knowledge! The following is a small series compiled by the self recovery fuse and temperature difference between the relay information:
Self recovery fuse self recovery fuse is made up of specially treated polymeric resin (Polymer) and conductive particles (Carbon Black) distributed inside it. In the normal operation of polymeric resin tightly conductive particles bound in the crystalline structure, form a chain conductive circuit, self recovery fuse is in a low impedance state at this time (a), the line passes through the heat generated from the current recovery fuse is small, does not change the crystal structure. When the circuit overload or short circuit occurs, large current flows through self recovery fuse the heat polymerized resin melt volume, rapid growth, the formation of high resistance state (b), the working current decreases rapidly, and thus restrict and protect the circuit. When troubleshooting, PTC self recovery fuse re cooling crystallization, volume shrinkage, conductive particles to form a conductive path, self recovery fuse to restore the low state of resistance, so as to complete the protection of the circuit, without manual replacement. Self recovery fuse application range:
Communication equipment, program-controlled switches, user terminal equipment, wiring security unit etc.. Automotive electronics: automotive wiring harness, car alarm, automotive micro motor, automotive electronics, etc.. Electronics industry: power supply ballasts, micro motors, fire alarm, instrumentation, etc.. Electrical equipment: satellite receiver, security equipment, speakers, industrial automatic control, etc..
   Of course, small talk about how the temperature relay temperature relay Bai, there must be a temperature sensor, there is some thermocouple, thermal resistance, thermal sensor signals are converted to electrical signals (because once the sensor temperature changes, but also changes the resistance, current changes), reached the action condition of temperature relay when it moves. Self monitoring camera equipment, aerospace, motor, electrical equipment and other industries for temperature control and thermal protection use. When the protected device reaches the specified value, the relay works immediately to cut off the power supply protection equipment. I believe we all should understand the difference between the self restoring fuse and the temperature relay!
