LK-JP

Low voltage integrated distribution box

LK-JP low-voltage integrated distribution box (hereinafter referred to as "integrated distribution box") is mainly suitable for transmission and distribution systems with AC 50Hz in urban and rural power grids and rated voltage below 0.4kV. It is installed and used on the low-voltage side of 10/0.4kV outdoor substations. It is a new type of outdoor low-voltage power distribution with functions such as power distribution, power metering, data acquisition, voltage monitoring, overcurrent protection, phase loss protection, low-voltage lightning protection, leakage protection, fault-removal automatic closing and reactive power compensation. It is also suitable for the corresponding on-site power distribution control, and can also be used as a supporting auxiliary device for other power distribution equipment. The integrated distribution box has the advantages of small size, easy installation, anti-theft of electricity, low cost, strong adaptability, aging resistance, accurate operation, no compensation errors, high protection level, perfect protection performance, and high degree of automation. It is an ideal power grid transformation. Preferred product.

Parameters

Technical parameter

◆The outdoor protection level reaches IP44, and the interior is set to five independent compartments: the incoming line measurement room, the incoming line switch room, the meter room, and the outgoing line switch room. The protection level between the compartments reaches IP30. The capacitor main switch control room and the capacitor operation and maintenance room are safely isolated;

◆In addition to the natural exhaust channel in the integrated distribution box, our company also installs an independent forced exhaust system for special high temperature and humid weather, and uses the temperature and humidity controller to set the temperature and humidity: humid heating , over-temperature exhaust, to stabilize the operating environment of the outdoor distribution box, improve the reliability of normal operation, and reduce potential safety hazards;

◆Isolation of the primary loop and the secondary control and measurement loop to avoid the failure of burning the company, which greatly improves the safety and reliability of operation;

◆The primary live part and the operation and maintenance interface are safely isolated to reduce the safety hazard to operators;

◆Increase the installation and maintenance space of the incoming and outgoing lines and the vulnerable and fragile components, so as to make the installation, maintenance and inspection convenient and fast;

◆Compensation capacitor adopts low-voltage intelligent integrated capacitor, which integrates compensation control, switching switch and dry compensation capacitor.
