Product Description

  As a professional manufacturer of power transmission and distribution equipment in China, Kexun's photovoltaic step-up box transformer is the key equipment in photovoltaic power generation system, which is mainly used to convert low-voltage DC generated by photovoltaic array into high-voltage AC and connect it to the power Basic composition of the YB-12 type Photovoltaic Step-up Box Transformer
  Photovoltaic step-up box transformer is usually integrated in a box by the following three parts: Photovoltaic inverter (optional part): Convert the direct current (DC) output by photovoltaic modules into alternating current (AC), and the common output voltages are 270V, 315V, 400V, etc. Step-up Transformer: Boost the low-voltage alternating current output by the inverter to the voltage level required by the power grid (such as 10kV and 35kV).
High voltage switchgear: Including circuit breakers, disconnectors, protective devices, etc., used for grid-connected control and system protection. Note: Some box transformers may not include inverters, but only boost transformers and high-voltage switches (called "pure boost box transformers").

Core functions of Photovoltaic Step-up Box Transformer
Voltage boost: meet the requirements of power grid for grid-connected voltage.
Electric energy isolation: the photovoltaic system is electrically isolated from the power grid through the transformer.
Protection function: over-current, over-voltage, short circuit, island protection, etc.
Monitoring and control: Support remote monitoring and collect data such as voltage, current and power in real time.

Photovoltaic Step-up Box Transformer technical characteristics
Efficient heat dissipation: ventilation or forced heat dissipation (such as fans and air conditioners) should be considered in the box design to avoid high temperature affecting the service life of the equipment.
Protection grade: usually IP54 or higher, dust-proof, moisture-proof and salt fog-proof (suitable for coastal or high-altitude areas).
Low-loss transformer: amorphous alloy or energy-saving silicon steel sheet is used to reduce no-load loss.
Intelligent grid connection: Support functions such as reactive power compensation (SVG) and harmonic suppression, and conform to power grid specification   Technical parameters
