GTDXF囗-12 AC metal solid insulated ring main switchgear
AC metal solid insulated ring main switchgear is a fully insulated, fully sealed, and maintenance free solid insulated vacuum switchgear. All high-voltage live parts are cast with epoxy resin material with excellent insulation performance, organically combining the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. into a whole, and the functional units are connected through fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, ensuring the reliability of equipment operation and the safety of operators. This ring main unit has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz, 12 kV power systems and widely used in industrial and civil cable ring networks and distribution network terminal projects. It is used for the reception and distribution of electrical energy, especially for urban residential distribution, small substations, switch stations, cable branch boxes, box type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, sports stadiums, railways, tunnels and other places. Due to its advantages of full insulation, full sealing, and full shielding, this product is particularly suitable for use in harsh environments such as high altitude, high temperature, humid heat, severe cold, and serious pollution.

- Product Description
-
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.
Features
- The protection level of the bus box reaches IP65, with waterproof, dust-proof, rust proof, and salt spray resistant properties, meeting the requirements for outdoor installation.
- Can simultaneously connect up to 24 battery strings.
- The positive and negative poles of each battery string are equipped with photovoltaic specific fuses to protect the module string in case of failure. The fuse base and fuses are used together to reduce the maintenance costs of the owner in the later stage and effectively protect the personal safety of maintenance personnel.
- The use of photovoltaic dedicated high-voltage lightning arrester can protect the positive and negative poles of the busbar after convergence, and the continuous working voltage (Uc) can reach 1000VDC.
- The power module inside the bus box can be connected to a photovoltaic voltage of up to 1000DCV.
- The measurement and control module of the bus box adopts reliable DC CT sensors to collect, monitor, alarm, and locate local faults for the current and bus voltage of each photovoltaic string. It can also measure the temperature inside the bus box, detect the status of lightning arresters and output circuit breakers, etc.
- The monitoring module inside the bus box has digital display function, which can display the current, bus voltage, temperature inside the bus box, status of circuit breakers and lightning arresters, system rate, and equipment address of each component string on the device.
- Capable of RS485/MODBUS-RTU serial communication.
- Both have lightning protection for external interfaces.
- Capable of receiving parameter downloads from local monitoring devices for analysis and processing.
- The working power supply of the bus box can be selected from external 220VAC/DC or the power supply provided by the bus box itself. If the power supply is provided by the bus box itself, it will be wired separately.
