Series three-phase dry-type transformers Dry-type transformer price
Shandong Chenyu Electric Co., Ltd.
The series of three-phase dry-type transformers
are mainly used for various high and low voltage complete sets of electrical, imported Used for controlling power and power supply in export equipment, precision machine tools, electroplating, lighting, heating, communications, chemical and other industry equipment, the series of three-phase dry-type transformers can effectively isolate some harmonics, with strong anti-interference and good safety characteristics. The series of three-phase dry-type transformers are the latest CNC series transformers developed by our company based on similar products of Siemens, especially the three-phase dry-type transformers between them. Their appearance and installation dimensions have been standardized and are common to the Siemens series. The products comply with,,,, etc. It complies with international and national standards and has the advantages of small size, light weight, simple maintenance and reliable operation. Design and production are strictly implemented in accordance with international standards and relevant national standards

Structural features of series three-phase dry-type isolation transformers
The core of series three-phase dry-type isolation transformers is made of high-quality cold-rolled silicon steel sheets. Depending on the insulation level, the whole body is impregnated with insulating paint of different insulation levels, which can effectively reduce the noise of the transformer and reduce the impact of salt spray, mold, etc. on the transformer. Depending on the protection level, the transformer box is made of high-quality steel plates. The structure not only fully considers air circulation, but also effectively plays a protective role. The transformer wiring cables are also easy to connect, and the design is full of humanization. Voltage ammeter, power indicator light, molded case circuit breaker, etc. can be installed according to user requirements.

Instructions for users of three-phase isolation transformers
Unpack and check whether the box has been damaged during transportation. Whether the technical documents, certificates, warranty cards and accessories in the cabinet are complete. Whether the transformer and other components are intact. Check whether the fasteners are loose or displaced, and whether the terminals have poor contact.
. Installation instructions: The installation site of the transformer must be dry and ventilated, without strong vibration, and without dust, sand, rainwater leakage. Care must be taken when relocating. Excessive tilting is strictly prohibited. After the installation is in place, the force on the chassis of the machine must be even. Place the box There should be enough space around the stable position to ensure ventilation and maintenance of the machine.
. Insulation requirements short-circuit the input and output terminals and lead out the test point. Use a megohmmeter to test the insulation resistance between the test point and the ground (machine shell). This value should be greater than megohm.
. Check the wiring. The first and most important task for debugging personnel is to carefully check the wiring. This work is the key to ensuring the reliable operation of the transformer and must be done carefully. The details are as follows
Check whether the main circuit wiring is firm and reliable, especially whether the wiring at the contact point of the air switch and the contactor is loose, it must be tightened.
Check whether the contact connections of various electrical devices on the back of the panel, such as voltmeters, ammeters, and indicator lights, are reliable. If they are loose, they must be tightened.
, series transformers should be used indoors. The normal usage conditions are
Ambient temperature ~+
The altitude does not exceed meters
Relative humidity
The installation site should not have a serious impact on the transformer. The installation site of gas, vapor, chemical precipitation, dust, dirt and other explosive and corrosive media with insulation strength should be free of severe vibration or bumps.
