Company firmly grasp the theme "endless innovation, intelligence to build the future", vigorously into resources, further innovation and development train of thought, seeking development in independent innovation.

General manager at huahong transformer Ye Yulei led; Huahong transformer manufacturing, vice manager JiWei dragons and research and development team, headed by liu zhijun said hundreds of day and night after the innovation of the study, through several times the pain of failure, finally, in December 2013 successfully developed a new product -- prepaid metering box.

In a series of preparation, development, trial operation and strongly support the leadership of the company and the technical personnel to fight next March 2014 will change the product finally officially put into use.

The product adopt AC 50Hz, 6-10kV three-phase power supply system for prepaid high voltage metering box or negative control, which is composed of high voltage vacuum load switch and measurement using the combination of dry type transformer, combined transformer voltage part at the same time set up special winding of switch power supply, switching mechanism with its overall appearance is small, convenient installation. Divided into high voltage vacuum switch in the room, combined transformer room two parts.
      My company metering box equipment with light weight, compact structure and is easy to install, reasonable design, simple structure, convenient construction features in the transformer industry in the lead. This product adopts special high voltage vacuum switch, with the high voltage metering box to ordinary compared with the outdoor vacuum breaker fission installation structure, the advantage of the investment cost can be reduced almost 50% won the praise of many partners, so is the first productive force of science and technology.
      After the installation of the metering device users must first to the business department to buy electricity, electricity, the device automatically power tripping (before power outage alarm notice), from the technical level to solve the problem in the user default electricity for a long time, meet the requirements for the management of electricity widely.
      This product should apply to between 200 and 1250 kVA transformer capacity of high voltage measurement of users, has the function of prepaid, preventing electricity-stolen, load control and so on, the device has high measurement accuracy and stable operation, low cost of characteristics. At present, the product has been officially put into use in instead.
