introduction：Electromagnetic controller220V,50/60HzThe alternating current is rectified into direct current，Then convert the direct current into a frequency of20-40KHzHigh frequency and high voltage，The high frequency and high voltage current flowing through the coil at high speed will produce a high speed changing alternating magnetic field，When the lines of magnetic force in the magnetic field pass through the magnetic conductive metal material, numerous small vortices are generated in the metal body，The metal material itself heats at a high speed，To heat the metal material inside the barrel。 Electromagnetic heating controller heating principle technology： The heating method used by plastic machinery in the domestic market is generally heating by electric heating ring，Heat is transferred to the barrel by contact conduction，Only the heat close to the inside of the barrel surface can be transferred to the barrel，Most of the outside heat is lost to the air，There is a heat conduction loss，And cause the ambient tempe

introduction：The master controller generally consists of a contact system、Operating mechanism、pivot、Gear reduction mechanism、CAM、The shell is composed of several parts。 Its operating principle is the same as that of the universal transfer switch，All rely on CAM to control the closing of the contact system。But compare that to the universal switch，It has a larger contact capacity，There are also more maneuvering gears。 The combination of different shapes of cams can make the contacts act in a certain order，The CAM Angle is determined by the structure of the controller，The number of cams depends on the requirements of the control line。 Because the control object of the master controller is the secondary circuit，So the working current of the contact is not large。The group of cams is combined with the corresponding contact system through the screw，The rotating shaft can be directly connected with the operating mechanism，It can also be connected with the reducer。If the number of circuits being controlled is

introduction：The controller adopts modular structure scheme，Simple structure、Easy to operate、High cost performance，Suitable for plastics、food、Packaging machinery and other industries。Distribution transformers are the most important and common primary equipment in the power supply chain。In our current distribution network，There are35KV/66KV/110KV/154KV/220KVSeveral voltage levels，In order to110KV/220KVGive priority to。There are about medium and high voltage substations in the country4Ten thousand，And that number is growing every year，Most of them are two transformers running side by side。 What is the operation mode of the intelligent controller？ Because the transformer in operation coil will heat up，Cooling measures are needed。Dry transformers can be used for small capacity transformers，Natural or forced air cooling。Large capacity transformers generally use oil as a cooling medium，Air cooling must be forced。 Both the primary coil and the core generate heat during transformer operation，Transformer oil flow th

introduction：What is a CAM controller？ Also known as contactor controller。Because it moves、The operation principle of the static contact is very similar to that of the contactor。As for the difference between the two，Only different from the CAM controller is manually operated，And can be replaced by most of the purpose of electrical appliances，The contactor system has an electromagnetic attraction to realize the remote operation mode of driving，The number of contacts is small。 Its a large control appliance，Its also multi-gear、multicontact，By hand，Turn the CAM to make and break the contact switch through the high current。CAM controller is mainly used to control the start of small and medium-sized winding rotor asynchronous motor in lifting equipment，stop，Speed regulation，Reversing and braking，It is also suitable for other electric drive occasions with the same requirements。 The working principle of CAM controller： The shaft of the CAM controller is covered with a lot of sleeves（Generally speaking12slice
