Product Details

Overview

PX(F) distribution box is a beautiful, novel, waterproof and dustproof power and lighting distribution box developed and improved by our company to meet the continuous updating of low-voltage electrical products and the higher requirements of users for the end distribution box in the low-voltage system. The distribution box uses advanced electrical components. Its main electrical properties, such as breaking capacity, thermal stability and insulation performance, can meet higher requirements to meet the needs of different users in industrial and civil buildings. The success of the trial production and application of the product, will fully replace the "XL-21" type and similar power distribution box, in the application has been welcomed by the majority of users.

Features

◆Collecting energy measurement, power, lighting distribution, reactive power automatic compensation and electric shock protection as a whole.

◆It has the advantages of small size, easy installation, lightning protection, low cost, strong adaptability, and accurate compensation.

◆ Easy to move as a whole, can be installed in the distribution transformer near the indoor or outdoor, can also be installed as a whole on the distribution transformer into one, can effectively prevent electricity theft.

◆ Reliable operation, high protection level, is the ideal product of rural power grid transformation.

There are a variety of box and specifications for users to choose, and can be customized according to user requirements.

Main technical parameters

◆ Rated voltage: 0.4kV

◆ Rated current: 50-400kV

◆ Rated frequency: 50Hz

◆ Rated leakage current: 0.03A-0.5A

Electric shock action current: ≤ 50mA

◆ Rated breaking time: ≤ 0.2S

◆ Delayed reclosing time:(20-60)S

◆ Capacitance compensation transformer capacity: 15%-30%

◆ The metering unit adopts 3 single-phase watt-hour meters or 1 three-phase watt-hour meter

Normal use environmental conditions

◆ The ambient temperature is not higher than 45 ℃, not low dry -25 ℃, and the daily average temperature is not higher than 40 ℃.

◆ The altitude shall not exceed 2000M.

The daily average humidity is not more than 95%.

◆ The inclination of equipment installation shall not exceed 5 °.

There is no violent vibration around, no corrosive gas and conductive dust.

internal structure

◆ The product must be opened by qualified professionals for operation, inspection and maintenance.

◆ The product is steel plate bending welding. Surface high voltage electrostatic spray treatment. Strong corrosion resistance and high protection level. The special metering room is equipped with an anti-pry lock to prevent electricity theft, and the door is open for operation and meter reading.

◆ Before installation, check whether the grounding element is damaged and whether the operation of each switch is flexible.

◆ Check whether the bus contact is good and the grounding device is reliable.

◆ During maintenance, the main switch should be disconnected first, and the capacitor can be discharged before maintenance.

The switch cabinet has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines, bus connection, etc. Mainly suitable for power plants, substations, petrochemical, metallurgical steel rolling, light industry and textile, factories and mining enterprises and residential areas, high-rise buildings and other different places. It mainly includes high-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic coincidence and segmenter, high-voltage operating mechanism, high-voltage explosion-proof distribution device and high-voltage switch cabinet.

Correct Selection of Breaker Breaking Capacity
On the primary system diagram, the selected circuit breaker, indicating the circuit breaker model, rated working voltage and rated working current, must also be selected for the breaking capacity of the circuit breaker. With user drawings, the breaking capacity of the circuit breaker is not selected, which makes it difficult for the manufacturer to carry out engineering design. The breaking capacity selection should be based on the system short-circuit parameters. If the manufacturer does not understand the system short-circuit parameters, it is difficult to make the correct choice. There are also some user drawings, regardless of the system short-circuit parameters, blindly select high-break parameters, resulting in unnecessary waste of funds. The correct choice of breaking capacity is very important, not only to ensure safe operation, but also to consider reducing product costs.
