Complete equipment of 10kV post-mounted transformer

The complete set of 10kV post-mounted transformer is a complete set of electrical equipment designed, developed and produced by Hechong Technology, 10kV transformer and low-voltage integrated distribution box (JP cabinet), outsourced fuse, lightning arrester, iron accessories, high and low voltage wires and cables, fittings and other accessories integrated into the same set of combined equipment. This equipment fully meets the requirements of the latest typical design scheme of the power grid company for the distribution station area, and can realize the full matching and one-stop supply of the typical design scheme "safely, economically, standard and simply. The main electrical wiring adopts overhead insulated wire or cable incoming line; the low-voltage outgoing line adopts overhead insulated wire or cable outgoing line, and is equipped with reactive power compensation. The station intelligent convergence terminal (TTU) can also be added as required to collect the operation information of distribution transformers to realize monitoring and protection of distribution transformers, management of electric energy metering equipment, management of electricity consumption load, management of electric energy quality, economic operation management of station areas, interactive management, monitoring and control of distributed energy on the user side connected to the public power grid, and management and bidirectional transmission of collected data to improve the power supply quality of the power grid and reduce the operation cost. Cooperate with low-voltage intelligent circuit breaker and intelligent reactive power compensation to realize intelligent monitoring, management and Internet of Things functions of the power grid.

Performance characteristics

1. Cost-effective, reduce the cost of power grid investment, improve the efficiency of equipment investment.

2. High degree of integration, design layout and construction installation difficulty is small.

3. Take the "standardized bench, modular components" approach, according to the installation conditions of flexible selection of standard bench and module combination, constitute a complete transformer table.

4. The main electrical wiring power supply is reliable, flexible operation, convenient operation and maintenance, saving investment and expansion requirements.

5. On the basis of meeting the needs of remote meter reading, low-voltage distribution network operation status monitoring and comprehensive management of power quality, the new intelligent fusion terminal in the station area can also be effectively compatible with new intelligent equipment such as low-voltage intelligent switches and phase change switches.
