Rural Network Integrated Distribution Cabinet

Comprehensive stainless steel outdoor stainless steel JP cabinet

Overview

JP series outdoor integrated power distribution box is a multi-function integrated metering, outlet, reactive power compensation and other functions to achieve outdoor integrated power distribution device, with short-circuit, overload, over-voltage, leakage protection and other functions, small size, beautiful appearance, economical Practical, installed on the poles of outdoor pole transformers, it is a new generation of ideal power distribution products for the transformation of urban and rural power grids. Stainless steel JP cabinet outdoor JP cabinet 200KVA With the continuous deepening of rural power grid transformation, a large number of JP cabinets are used in rural power lines and various distribution stations. JP cabinet is designed to meet the requirements of standardization, miniaturization and outdoor type of rural low-voltage power distribution devices. It integrates power distribution, metering, protection (overload, short circuit, leakage, snow protection), and capacitive reactive power compensation. To

Stainless steel JP cabinet outdoor JP cabinet 200KVA has the following characteristics

The JP cabinet has three basic functions: metering, power distribution, and reactive power compensation. It can be flexibly configured according to user needs. There are seven configuration schemes of metering + power distribution + compensation, metering + power distribution, power distribution + compensation, metering + compensation, metering, power distribution, and compensation.

Normal use environment

◆ Environmental temperature: -25℃+40℃;

◆ Air relative humidity: the daily average value is not more than 90%, and the monthly average value is not more than 90%;

◆ Altitude: not more than 2000m;

◆ Install in a place where there is no severe vibration and impact, and no corrosive gas.

Structural features

The box structure is vertical and horizontal. It adopts honeycomb structure stainless steel double sandwich composite board, which has the properties of flame retardant, environmental protection, heat insulation and anti-condensation. It adopts special stainless steel welding technology. After the box is formed, the overall strength is high. It is as clean as a mirror, leaving no traces of welding seam; the internal installation beam (plate) is processed by hot-dip galvanizing process to ensure that it will not rust within 20 years; the front and rear doors of the box are open for user operation and maintenance, and the doors are inlaid with high elasticity and anti-aging seals Adhesive strips, each door is equipped with two types of door locks, light and dark, the open lock is equipped with anti-blocking and anti-rust rain cover; the measuring room is fully enclosed with a lead sealing device; the side of the box is equipped with a rain-proof and ** incoming cable Through the pipe, there are ventilation holes and cable outlets at the bottom

The whole cabinet structure is assembled with stainless steel 304, and the thickness of the cabinet is 1.5mm. The distribution box body can be rainproof, dustproof, anti-theft, anti-leakage, anti-lightning, anti-electromagnetic interference, and has enough strength to ensure that it will not be deformed during transportation and installation.

Complete functions, with manual and automatic switching operation modes. Complete protection functions: overvoltage, overload, undervoltage, undercurrent, short circuit, phase loss, zero sequence overrun and other functions.

The response is fast, the compensation effect is good, and the work is reliable.

When the transformer is running, a large amount of heat will be generated in the box change and dissipate to the transformer room. Therefore, the heat dissipation and ventilation of the transformer room are the key issues that should be considered in the design of the European box change. The temperature of the transformer room keeps rising, especially when the ambient temperature is high, the temperature rises faster, so only relying on natural ventilation to dissipate heat often cannot guarantee the reliable and safe operation of the transformer; in the European box transformer design, except for the box transformer with small transformer capacity In addition to natural ventilation, temperature measurement protection is generally designed, and forced exhaust measures are used to solve the problem. The system mainly consists of a measuring device, which can measure the room temperature and oil temperature of the transformer. Then through the manual and automatic control circuit, whether the exhaust fan needs to be put into operation is set and controlled according to the setting range of the reliable and safe operating temperature of the transformer.

In the European box substation, the transformer can be either an oil-immersed transformer or a dry-type transformer. However, because the price of dry-type transformers is relatively high, oil-immersed transformers should be used to reduce manufacturing costs if the user has no special requirements. . The transformer capacity is generally 100-1250KVA, and Yuli should not exceed 1600KVA.

The grounding protection is complete. The lower part of the cabinet is provided with a main grounding screw and marked with a grounding sign. The door and the cabinet are connected by yellow and green two-color wires. The entire low-voltage switchgear forms a complete grounding protection circuit.
