introduction：a.When the load is inductive，Such as DC solenoid valve or electromagnet，A diode should be connected in parallel at both ends of the load，The current of the diode should be equal to the operating current，The voltage should be greater than the operating voltage4times； b.Solid state relays should work as close to the load as possible，The output leads should meet the needs of the load current； c.The power supply used is derived from AC step-down rectification，The filter electrolytic capacitor should be large enough； d.Solid state relays are more sensitive to over load capacity，Must use a quick fuse orRCThe damping circuit protects it。The load of a solid state relay is obviously related to the ambient temperature，Temperature rise，Load capacity will decline rapidly。

introduction：The main circuit uses two one-way thyristors in reverse parallel，The trigger circuit uses optocouplings to isolate the trigger，General use of DC constant current circuit control，The voltage range is mostly4-32V，There are also direct use of resistors in series on the optocoupler input side，This controls a narrow voltage range。 The thyristor can be switched on in two ways： Zero crossing type and random type。 The zero crossing mode is only switched on and off when the sine wave is near the zero crossing point，This is less disruptive to the grid。 The servo is at the same time as the control voltage is given，The thyristor will trigger it，Its more disruptive to the grid，But it can be phase-shifted，Realize stepless control。

introduction：Temperature relay adopts bimetal plate as operating element，Simple and compact structure，Outline structure、duckbill，The bimetallic element is enclosed in the housing with epoxy resin，encrust0.4mmthickh68Made of stretched brass tape，Good thermal conductivity。 When temperature relays are used for motor protection.The motor windings should be buried in advance and then dipped in paint，In order to ensure good hot joint performance and when used for medium temperature control.The temperature relay should be placed directly into the controlled medium。When some reason causes the winding temperature or medium temperature to rise rapidly.The temperature relay immediately senses the increase in temperature，And through the housing to transmit the temperature to the internal dual-group element，Bimetallic elements are thermally sensitive and gradually accumulate energy，When the temperature relay feels that the temperature reaches the rated operating temperature, the bimetal element will immediately act，Disconnect the norm

introduction：In order to increase the rate，Worm gear reducer is generally made of non-ferrous metal worm gear，The worm is made of harder steel。Because it is a sliding friction drive，More heat will be generated during operation，The thermal expansion of the reducer parts and seals is different，Thus a gap is formed on each mating surface，The lubricating oil thinns as the temperature rises，Leak prone。
