Main functions and structural features of the product

Main functions of the product:
1. Power distribution function: completely replace the traditional power distribution box function in the past
2. Metering function: the controller integrates precise metering devices, which can monitor, record and save various indicators of electric energy
3. Compensation function: At the same time of power distribution, reactive power compensation can be automatically performed on the line as needed
. 4. Communication function: with its own wireless communication module, the operator can operate the equipment remotely (including: reading data, setting settings, remote manual switching, etc.)
5. Display function: full Chinese interface, which can display the three main parameters of the power grid, such as voltage, current, harmonic voltage, harmonic current, active power, reactive power, active energy, reactive energy, power factor, and the operating status of the capacitor in real time.
6. Protection function: It has perfect alarm and action functions such as over-voltage, under-voltage, phase loss, zero-sequence current (load imbalance) exceeding the standard, and harmonic exceeding the standard to protect the safety of the equipment.
7. Recording function: It can record the voltage, current, active power, reactive power, active power, martial arts electroplating, power factor, harmonic distortion, 3, 5, 7, 9, 111, 13, sub-harmonic and voltage online every month and every day Maximum and minimum values and when they occurred. It can record all the operation time, including events such as device up and down points, manual input/removal of capacitors, etc., to provide the necessary basis for accident analysis. The switching process of reactive power compensation capacitors can be recorded, providing intuitive information for users to understand the effect of reactive power compensation in detail.
Product electrical features:
1) The electrical scheme fully considers the characteristics of the power grid, and is designed for safety, reliability and ease of use, taking into account the characteristics of small towns, and is also suitable for industrial and mining enterprises.
2) Considering the respective characteristics of rural power grid and urban power grid, we select high-performance reactive power compensation controllers suitable for power grid transformation requirements according to specific conditions, and can also add leakage protectors according to user needs.
3) The executive element of 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 capacitors, the power factor can be improved, energy can be saved, and the quality of power supply can be improved.
5) The response is timely and fast, the compensation effect is good, and the work is reliable, and leakage protectors can also be added according to user needs;
6) Protection functions: overvoltage, overload, undervoltage, undercurrent, short circuit, phase loss, zero sequence overrun, etc. ;
7) Automatic operation function: push out after power failure, and automatically recover after 10s delay after power transmission;
8) It can improve the power factor of the grid to above 0.95;
9) It is made of stainless steel or SMC material, molded under high temperature and high pressure, with high strength, 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;
11) Excellent electrical insulation can ensure indoor and outdoor use Safety;
12) Good corrosion resistance and anti-aging performance, can be used in a variety of complex environments, and the service life can reach 20 years;
13) The combined box is easy to install, and the flexible combination can meet the needs of various spaces.

Cabinet structure:
1. The frame is fully assembled with section steel and partially welded. Its rigidity and bearing capacity meet the installation requirements of electrical components. The metal parts of the cabinet are anti-corrosion measures galvanized or electrostatic sprayed.
2. The main busbars are arranged behind the upper part of the cabinet, and the busbar clamps are used as a building block combination structure, which has high mechanical strength and insulation strength, and can withstand an effective value of 15kA and a peak value of 30kA.
3. The shell is made of stainless steel, which is anti-corrosion. Rubber inserts are added to the edge of the door. When the door is closed, the inserts between the door and the cabinet have a certain compression stroke to prevent direct collision between the door and the cabinet. And improve the protection level of the door.
4. The instrument door equipped with electrical components is connected to the housing with multi-strand annealed copper wires, and the mounting parts in the cabinet are connected to the housing with grounding knurled screws to form a complete grounding protection circuit.
5. The protection level of the shell reaches IP44.
