Transformer

The open-close current transformer is mainly used for cables and copper bars. It has simple structure, reasonable design and flexible application. According to the specifications of the copper bars used in the main circuit, there are many kinds of through holes corresponding to each other. The primary current of the main circuit includes 50A ~4000A, and the rated secondary output current is 1A~5A (0~1V). This series of products can meet the technical requirements of grade 0.2, grade 0.5, grade 1 and other different precision.

LDZC-10 current transformer is suitable to be installed on the special inflatable cabinet for the measurement and protection of current and zero sequence current. 

LMZT-10 current transformer is suitable to be installed on the special inflatable cabinet for the measurement and protection of current and zero sequence current. It can also be used for the measurement and protection of zero sequence current of multiple cable circuit. The iron core and secondary winding of this series of current transformers are vacuum-cast with high quality epoxy resin in a  flame-retardant plastic housing, which is moisture-proof, stable and maintenance free.

Open-close outdoor waterproof puncture transformer is the waterproof function, which can be used outdoors. Its section port is surrounded by rubber pads to prevent rain from entering. Of course, most so-called waterproof transformers on the market use rubber pads as a means, but there are also limitations in using this means for waterproofing. Because it is impossible to guarantee the water proof of the transformer itself ,our company adopts the technology of transformer forming once, that is, the transformer is directly made into a solid in the mold, and the plastic is w=rapped around the whole body without any gap. Meanwhile, waterproof terminals and sheath lines are used in the secondary side leads to ensure that no rain can enter the transformer body. Our company transformer waterproof grade has reached IP67/IP65. This product meets part of the standard GB20840.1.2 . 

The open-closed current transformer is improved on the basis of the traditional transformer. Made of free opening and closing, it can be quickly installed and disassembled in the state of no power failure and no wire disassembly, and the operation is sample. This series of products has a wide measuring range, rated primary current range 5~630A, rated secondary current range 0~5A, current ratio range can reach 500:1~ 10 000:1, orderly production process, to ensure its accuracy level, reliability and other technical requirements. This products complies with GB/T20840.1.2 Standard.

The open-closed type AC Transmitter is a kind of DC4~20mA( Through 250KV) which can directly convert the AC current of the main circuit to linear proportion Ω Resistance conversion DC 1~5V or through 500V Ω Resistance conversion (DC1~10V) constant current ring standard signal measuring instrument, AC current transmitter has the advantages of high precision, fast response, small volume, low power consumption, wide frequency response, anti-interference, lightning wave and shock wave protection.

The rail type AC transmitter can directly convert the AC current of the main circuit to DC4~20mA (through 250KV) output in linear proportion Ω Resistance conversion DC 1~5V or through 500V Ω Resistance conversion (DC1~10V) constant current ring standard signal measuring instrument, AC current transmitter has the advantages of high precision, fast response, small volume, low power consumption, wide frequency response, anti-interference, lightning wave and shock wave protection.

The circular open-closed hall current sensor is mainly suitable for the isolation and conversion of complex signals such as AC, DC, pulse, etc. Through the Hall effect principle, the converted signal can be directly collected and accepted by carious acquisition devices such as ad, DSP, PLC, secondary instrument etc., with fast response time, wide current measurement range, strong overload capacity, good linearity and strong anti-interference ability. Easy to install, removable installation.
