Motor Control Box

Product Overview

The outdoor integrated distribution box (JP cabinet) is a new type of outdoor power distribution reactive power compensation integrated cabinet designed based on the principles of safety, economy, reasonableness and reliability. It is suitable for AC 50Hz, rated voltage 380V power distribution systems such as urban power grids, rural power grid transformation, industrial and mining enterprises, street lighting, residential areas, etc. It is a new type of outdoor integrated power distribution box with multiple functions such as power distribution, control, protection, reactive power compensation, and power metering. At the same time, leakage protection functions can be added according to user requirements. The product has the advantages of novel and reasonable structure, high protection level, convenient installation, debugging, maintenance and inspection.

The product complies with GB7251.1, GB7251.12 "Low-voltage complete sets of switchgear and control equipment", GB/T15576 "Low-voltage complete sets of reactive power compensation devices", and has passed 3C certification. It is an ideal low-voltage complete set of devices in the current power grid transformation. The outdoor integrated distribution box (JP cabinet) is suitable for electric energy distribution, metering, protection and automatic compensation of reactive power at 0.4kV voltage level.

Normal Use Condition

The ambient air temperature is not higher than +40°C, not lower than -5°C, and its average temperature within 24 hours is not higher than +35°C.

Weather conditions, the air is clean, and the relative humidity does not exceed 50% at the maximum temperature of +40°C. Higher relative humidity is allowed at lower temperatures, such as 90% at +20°C, but it should be taken into account that moderate condensation may occasionally occur due to temperature changes. Altitude ≤2000m.

This product is suitable for transportation and storage at the following temperatures: -25°C to +55°C, up to +70°C in a short period of time (no more than 24 hours). The device should not suffer any irreversible damage at these extreme temperatures, and should be able to work normally under normal conditions.

If the above conditions of use cannot be met, the user should propose it to the manufacturer when ordering and negotiate a solution.

Product Features

·The response is timely and rapid, the compensation effect is good, and the operation is reliable. Leakage protectors can also be added according to user needs.

·Protection functions: overvoltage, overload, undervoltage, undercurrent, short circuit, phase loss, zero sequence overrun and other functions.

·Automatic operation function: launches after power outage and automatically resumes after 10s delay after power supply.

·Can improve the power factor of the power grid to above 0.95.
