New energy grid cage

The new energy grid connected cage is an important power protection part suitable for photovoltaic string type power generation systems, which connects the string type inverter with the power grid system. The circuit protection part adopts photovoltaic grid connected circuit breakers and pull ring isolation switches, and with secondary lightning protection. The protection level is IP65, which meets the requirements of outdoor installation and meets waterproof, dustproof, UV resistant, salt spray corrosion resistant, etc. The internal structure of this product is simple and clear, with neat and reasonable wiring. High reliability and easy maintenance. Outdoor wall mounted installation can adapt to various harsh environments. In addition to standard materials and sizes, customization can be made according to user requirements.

New energy DC bus box

The new energy DC bus box combines the DC inputs of up to 24 photovoltaic cell modules into one or multiple outputs, each with a fuse, and the outputs are equipped with lightning arresters and circuit breakers, greatly simplifying the input wiring of DC distribution cabinets and inverters. Provide lightning protection, short circuit protection, and grounding protection. The bus box is divided into two types: intelligent and non intelligent. The intelligent lightning protection bus box is equipped with a combiner monitoring unit inside, which can monitor the input current of each photovoltaic cell string, summarize the output voltage, temperature inside the box, and the status of lightning protection devices, circuit breakers, etc. The internal layout of the device is simple and clear, with neat and reasonable wiring. High reliability and easy maintenance. Outdoor wall mounted installation can adapt to various harsh environments. Except for the core components, other components can be customized according to user requirements.

DXF Gas insulated switchgear

The gas insulated switchgear is widely used in 10kV/6kV distribution systems, which is the choice of switch products for various users in urban and rural power distribution systems. The switchgear is modular unit mode, which can be combined according to different purposes; There are two main categories: fixed unit combinations and expandable units, which meet the flexible use needs of various substations for compact switchgear. Gas insulated switchgear is a completely sealed system, with its charged components and switches enclosed within a stainless steel body. The whole switch device is not affected by external environmental conditions, ensuring operational reliability and personal safety, and realizing maintenance free. By selecting expandable busbars, any combination can be achieved to achieve full modularity. The expansion of busbar safety insulation and shielding ensures reliability and safety. The gas insulated switchgear can also provide TV based automation solutions, forming the concept of intelligent switches and minimizing on-site installation and debugging workload. The gas insulated switchgear is divided into non expandable standard configuration and expandable standard configuration. Due to its combination of full and half modules and self-extensibility, it has extremely special flexibility. Gas insulated switchgear shall comply with GB standards. The design lifespan for operation under indoor conditions (20 ℃) exceeds 30 years.

VS1-12 Vacuum circuit breaker

VS1-12 vacuum circuit breaker, an indoor switchgear for three-phase AC 50Hz power systems with a rated voltage of 12kV. It serves as a protection and control unit for power grid equipment and power equipment in industrial and mining enterprises. Suitable for places that require frequent operation at rated working current, or multiple disconnections of short circuit current. The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit.
