Product Overview
The JP series low-voltage integrated power distribution device (hereinafter referred to as the integrated distribution box) is mainly suitable for 50Hz AC power distribution systems with a rated voltage of 0.4kV or less in urban and rural power grids. It is installed on the low-voltage side of a 10/0.4KV outdoor substation; it integrates multiple functions such as power distribution, power metering, data acquisition, voltage monitoring, overcurrent protection, phase failure protection, low-voltage lightning protection, leakage protection, automatic reclosing after fault clearance, and reactive power compensation. This new outdoor low-voltage power distribution device has advantages such as small size, easy installation, anti-theft, low cost, strong adaptability, anti-aging, accurate commissioning, and no compensation error. It also has high protection level, complete protection performance, and high degree of automation. It is also suitable for on-site power distribution control and can be used as a supporting auxiliary device for other power distribution equipment, making it an ideal product for grid transformation. This product complies with GB7251.1 standard and has passed CQC certification. The reactive power compensation device has passed the testing of the quality inspection and testing center, and all indicators meet the JB7113 standard for "Low-voltage parallel capacitor devices".
The metering device is designed and installed with three single-phase low-voltage test meters or a three-phase four-wire electricity meter. The accuracy level of the current transformer is 0.2S, which is conducive to the balance of the three-phase load and ensures accurate metering.
The reactive power compensation device uses fixed or automatic compensation, and the compensation capacity is greater than or equal to 15~20% of the transformer capacity. A leakage protection device and an AC contactor are installed. The leakage protection device has short-circuit, overload, leakage, and alarm functions; it works with the AC contactor to achieve automatic reclosing, and it can also be used with a household leakage protector to achieve hierarchical protection, ensuring safe operation of the equipment and preventing accidents caused by leakage.
The integrated distribution box is made of matte stainless steel or SMC material. This box has good heat dissipation, rainproof, dustproof, anti-condensation, anti-heat radiation, and anti-light pollution characteristics.
