Ⅰ.Overview

The comprehensive distribution cabinet (JP cabinet) of distribution transformer is designed according to the requirements of power grid construction and transformation and power grid operation experience and based on the principles of safety, economy, rationality and reliability. It is a new outdoor comprehensive distribution box with multiple functions such as power distribution, control, protection, reactive power compensation and power metering. At the same time, it can add leakage protection function according to the requirements of users. The product has the advantages of novel and reasonable structure, high protection level, convenient installation, commissioning, maintenance and overhaul, etc. The product conforms to gb7251.1-1997 and has passed 3C certification. It is an ideal low-voltage complete device in power grid transformation. Distribution transformer integrated distribution cabinet (JP cabinet) is suitable for power transmission and distribution systems with AC 50Hz, 0.5kV voltage level and rated voltage below 0.4kV. This series of products integrates automatic reactive power compensation and power distribution. It is a new type of indoor and outdoor low-voltage distribution cabinet integrating multiple functions such as electric energy measurement, leakage protection, overcurrent, overvoltage and phase loss protection. It has the advantages of small volume, easy installation, low cost and anti electricity theft, It has the advantages of strong adaptability, aging resistance, accurate operation and no compensation misunderstanding. It is the preferred product for power grid transformation

This integrated distribution box (JP cabinet) is made of high-quality 304 stainless steel. Simple appearance and convenient installation. After electrostatic spraying, the steel plate can effectively reduce outdoor light pollution and increase the service life of the box. After foaming treatment, the door panel is more firm and not easy to deform. The box lock adopts American box transformer lock to enhance the ability of anti-theft. Triangular iron lifting rings are installed on both sides of the box to facilitate installation and commissioning on the construction site.

Main functions of the product

1. Distribution function: completely replace the traditional distribution box function in the past

2. Metering function: accurate metering devices are assembled in the controller, which can monitor and record various indexes of electric energy and save them

3. Compensation function: it can automatically compensate the reactive power of the line as needed while distributing power

4. Communication function: equipped with wireless communication module, the operator can operate the equipment remotely (including reading data, setting, remote manual switching, etc.)

5. Display function: the full Chinese interface can display the three main parameters of power grid voltage, current, harmonic voltage, harmonic current, active power, reactive power, active kwh, reactive kwh, power factor and the operation state of capacitor in real time.

6. Protection function: it has perfect over-line alarm, over-voltage, under voltage, phase loss, zero sequence current (load imbalance) exceeding standard, harmonic exceeding standard and other alarm and action functions to protect equipment safety

7. Recording function: it can online record the maximum and minimum values of voltage, current, active power, reactive power, active kwh, martial electroplating, power factor, harmonic distortion, 3, 5, 7, 9, 111, 13, subharmonic and voltage and their occurrence time every month. It can record all operation time, including events such as upper and lower points of the device, manual input / removal of capacitance, etc., so as to provide necessary basis for accident analysis. It can record the switching process of reactive power compensation capacitor and provide intuitive information for users to understand the effect of reactive power compensation in detail.

Product electrical characteristics

(1) The electrical scheme fully considers the characteristics of the power grid, is designed based on safety, reliability and ease of use, and takes into account the characteristics of small towns. It is also suitable for industrial and mining enterprises.

(2) Considering the respective characteristics of rural power grid and urban power grid, we select a high-performance reactive power compensation controller suitable for the transformation of power grid according to the specific situation, or add leakage protector according to the needs of users.

(3) The actuator for capacitor switching can adopt electronic switch or special AC contactor according to the user's requirements.

(4) By selecting high-performance metallized polypropylene film self-healing low-voltage shunt capacitor, the power factor can be improved, the electric energy can be saved and the power supply quality can be improved.

(5) Timely and rapid response, good compensation effect and reliable operation. Leakage protector can also be added according to user needs;

(6) Protection function: overvoltage, overload, undervoltage, undercurrent, short circuit, phase loss, zero sequence overrun and other functions;

(7) Automatic operation function: automatic recovery after 10s delay after power failure and power transmission;

(8) It can improve the power factor of the power grid to more than 0.95;

(9) SMC material is used and molded under high temperature and high pressure, with high strength, high modulus and good impact resistance;

(10) The weight is 1 / 3 lighter than the metal box of the same specification, which can replace the metal box and greatly save metal materials;
