Environmentally friendly metering cabinet
Dingli Electric's main products include five series: environmentally friendly ring main units, environmentally friendly high-voltage metering cabinets, deeply integrated pole-mounted switches, European-style box-type transformers, Siemens-authorized NXAirsLP medium-voltage cabinets and SIVACON 8PT low-voltage cabinets, and Eaton-authorized RVAC ring main units.
The DLHM-12 environmental protection type outdoor high-voltage energy metering box is developed for the needs of the power system. It perfectly combines the ownership boundary point and the metering point and has an intelligent intelligent boundary switch function. The product shell is made of stainless steel and is treated with anti-sticking spray coating. The protection level reaches IP44. According to different functions, it is divided into four independent compartments: high-voltage switch room, metering room, inlet room, and outlet room. The vacuum circuit breaker and metering current transformer both adopt a fully sealed and fully insulated structure, with strong weather resistance and safety. During use, the metering CT change can be selected from 5/5A-600/5A to meet the needs of different customer loads.
The YB囗-40.5/0.69-6300 photovoltaic centralized inverter integrated unit includes all or part of the intelligent control and measurement unit, remote communication unit, DC input unit, inverter unit, low-voltage AC unit, step-up transformer, and high-voltage protection switch unit. Highly system-integrated, it achieves automation and a simple, reliable communication interface. The YB囗-40.5/0.69-6300 series intelligent photovoltaic prefabricated substation is mainly used in the array area and station area of photovoltaic power generation systems. Its main function is to convert the DC power generated by photovoltaic modules into AC power at industrial frequency and transmit it to the grid through on-site voltage stepping up. The design, production, and testing of the YB囗-40.5/0.69-6300 series intelligent photovoltaic prefabricated substations follow the T/CEEIA 231-2016 standard for intelligent photovoltaic prefabricated substations.
The DLNH101-12 type environmentally friendly gas-insulated ring main unit (GIS) enclosure is filled with dry air at a pressure of 0.02 MPa and can operate at zero gauge pressure. A pressure equalization hood is used to optimize the electric field within the enclosure, creating a slightly non-uniform electric field to ensure insulation performance. There are no inter-phase insulating barriers, and the contacts are not encapsulated. The structure is simple, eliminating the risk of insulation aging and failure. The design concept of a minimum functional pressure as low as zero gauge pressure reduces equipment leakage and ensures that the equipment's insulation performance is not reduced even when the equipment leaks to zero gauge pressure, allowing for ample time to schedule power outages for inspection and maintenance, thereby increasing equipment reliability.
The RMDL-12 outdoor high-voltage ring network energy metering box is a combined electrical appliance of an outdoor ring network box and a metering device, developed to meet the metering needs of power systems. Based on the traditional SF6 insulated ring network box, a metering device is added to each outgoing line, enabling each outgoing line section to have an independent metering function. The SF6 insulated ring network box and metering current transformer both adopt a fully sealed, fully insulated structure, so the equipment has strong weather resistance and safety. During use, users can conveniently replace the CT ratio according to load changes, making metering more accurate. When replacing the current transformer, only the circuit breaker needs to be opened, the isolating switch opened, and then the grounding switch closed, to allow for transformer replacement, greatly reducing the power outage area. The current transformer ratio can be selected from a full range of 5/5A to 600/5A, facilitating user selection for different loads. A DTU position is reserved to meet the requirements of the integration of primary and secondary equipment.
