Next, please go to the exhibition site and have a look.

1. Solution of photovoltaic series inverters

Solutions for photovoltaic series inverters are GHX5 series disconnectors, which are developed independently and have independent intellectual property rights. They can be connected in the same direction and operate more conveniently. With the high performance GM8i AC plastic case circuit breaker series and GW7 AC frame circuit breaker series, the system solution with higher reliability and safety is composed, and the product voltage level can reach above AC800V.

2. Solution of Photovoltaic Centralized Inverter

In order to meet the demand of photovoltaic centralized inverters for circuit breakers, we have developed GW7 AC frame circuit breaker series, which has the characteristics of low temperature resistance, high insulation, small size, etc. The width of the drawer type of 3P/2000A is 280mm, easy to install, and the structure is patented with higher reliability. GM51 DC plastic case circuit breaker rated voltage can reach DC1500V, rated working current can reach 1600A; GM8i AC series rated voltage can reach AC1000V, rated current to 1600A, to meet the needs of different systems; GHR1 fuse disconnector, positive and negative integration, reducing the size of the shunt box, and can be electrically plugged in DC1000V system, more convenient maintenance.

3. Energy Storage System Solutions

GM51 DC plastic case circuit breaker series and GW51 frame circuit breaker series developed by Beijing People's Electrical Appliance Factory Co., Ltd. adopt low exclusion point and reverse technology and special patented structure design of exclusion and clamping, which makes the operation more reliable and has higher electrical life. The rated working voltage can reach DC1500V and the rated current is 1600 A. Small size, high interruption, excellent current limiting effect, with thermomagnetic adjustable function; thermal adjustable range is 0.8In-1.0In, magnetic adjustable range is 5In-10In, to meet different user needs. Modbus communication function is provided through built-in module, Bluetooth module is optional, and wireless communication to external display, read, set and control functions, providing output of remote transmission trunk node of release signal.（ Self-reduction).

4. Solution of Wind Power System

GW7 series special universal circuit breakers for new energy are suitable for box substations with AC 50Hz, rated working voltage 400/690/1140V, rated working current 4000A or less, and main tower of wind farm. They are used to protect lines and power supply equipment from overload, undervoltage, overvoltage, short circuit, grounding, unbalanced current and other faults. Circuit breaker adopts intelligent controller with precise selective protection and multi-function, which has complete protection function. It is especially suitable for distribution network which needs to improve the reliability of power supply and avoid unnecessary blackouts.

GC6 series of high performance contactors, small size, light weight, low temperature rise terminal, low power consumption, coil control circuit with wide voltage + PLC control module.

The working environment temperature of GC6 series and GW7 series can reach - 40 C~+70 C, which effectively guarantees the reliable operation of the system.
