The CNLX-PV intelligent photovoltaic lightning protection combiner box combines the DC inputs of 24 photovoltaic cell modules in series into one or more outputs, each equipped with a fuse, and the output is equipped with a surge arrester and circuit breaker, greatly simplifying the input wiring of the DC distribution cabinet and inverter. It provides lightning protection, short-circuit protection, and grounding protection. Combiner boxes are divided into intelligent and non-intelligent types.

The HJLX-AC photovoltaic AC combiner box is an important component suitable for string power generation systems in photovoltaic string power generation systems, supporting string inverters and AC distribution cabinets or step-up transformers. The incoming line of this combiner box uses circuit breaker input, and the output uses circuit breakers or load isolating switches.

The photovoltaic grid-connected box is used for PV power stations built near the user's site. It operates on a self-consumption model on the user side, with excess electricity fed into the grid. To ensure safe system operation, coordinate safety between the inverter and the utility grid, and improve system reliability and energy metering, this PV grid-connected distribution box was designed.

The CNBWG photovoltaic grid-connected cabinet is an important component connecting centralized inverters with step-up transformers or AC combiner boxes with step-up transformers. The cabinet's incoming line uses a circuit breaker input or direct input, and the output uses a circuit breaker or load isolator switch. The busbar uses plated or purified busbar connections and provides secondary lightning protection.

The KYN61-40.5(Z) armored removable AC metal-enclosed switchgear (hereinafter referred to as the switchgear) is an indoor complete power distribution device for three-phase AC 50Hz with a rated voltage of 40.5kV. It is used in power plants, substations, and industrial and mining enterprises for receiving and distributing electricity. It provides functions such as control, protection, and monitoring of circuits and can also be used in places where frequent operation is needed.

This product complies with relevant national standards such as the "Photovoltaic Power Generation Design Specification," "Technical Regulations for Distributed Generation Grid Connection," and "3.6kV~40.5kV Switchgear and Control Equipment," and is suitable for high-voltage access switchgear stations in distributed and terrestrial photovoltaic power generation (also known as high-voltage grid-connected complete switchgear sets).

The box transformer is divided into three parts: the high-voltage chamber, the low-voltage chamber, and the transformer, which can be arranged in either the character "目" (eye) or the character "品" (pin).
The inner and outer surfaces of the cabinet are smooth and free of rust, with coating peeling and dent damage. The coating layer is firm and uniform, with no obvious contrast or reflection.

The 35kV photovoltaic (PV) step-up substation boosts the three-phase AC power generated by a solar box-type inverter station or inverter room through a step-up transformer to 35kV three-phase AC power for grid integration. The PV box-type step-up substation features a reasonable and compact system layout, including a low-voltage incoming cabinet, dual split transformers, and a high-voltage outgoing cabinet.

A modular transformer is a transformer that combines the booster transformer body, switchgear, fuse, tap changer, and corresponding auxiliary equipment. The high-voltage switch and fuse are all installed inside the oil tank, and the overall size is relatively small.

HuaBian is developed by Chinese designers drawing on the excellent cooling performance of MeiBian and the comprehensive protection features of OuBian, optimizing a compact structural design. It solves the problem of insufficient protection in MeiBian and poor cooling in OuBian, and currently has good market promotion prospects.
