Low-Voltage Dynamic Reactive Power Compensation Device

Description

Overview

The low-voltage dynamic reactive power compensation device is used in AC power systems with a voltage rating of 1 kV and below. It has dynamic continuous reactive power compensation, which improves the power factor, reduces voltage and power fluctuations, enhances transmission capacity, and improves both economic and social benefits. This device can be widely used in industrial and residential power distribution networks, such as for machines, electric furnaces, motors, electric buses, and vehicles with large reactive power loads.

Using Environmental Conditions

• Altitude: ≤ 2000 m
• Ambient temperature: Indoor installation: ≥ -5°C, ≤ 40°C (recommended for indoor ventilation); Outdoor installation: ≥ -25°C, ≤ 45°C.
• Relative humidity: For indoor installation: 40°C at >50%, 20°C at ≤ 90%; for outdoor installation: 20°C at 100%.
• Surrounding environment: No explosive or flammable hazards, no corrosive gases or conductive dust; free of electric and magnetic fields that may damage the equipment.
• Installation site: No severe vibration or shock, installation tilt ≤ 5°.
• Voltage fluctuation range: ± 15% of rated working voltage.

Product Characteristics

The low-voltage reactive power compensation cabinet consists of isolation switches, circuit breakers, fuses, electrical connectors, overload relays, and intelligent power capacitors. The cabinet is designed as a sealed structure.

Main Performance

• Response speed and compensation effect are excellent, and the device is reliable. It can also be equipped with a user-required circuit breaker for power supply protection.
• Protection functions: Overvoltage, overload, undervoltage, undervoltage, short-circuit protection, etc.
• Operation modes: Both automatic and manual modes are available.
• Effective compensation factor to improve the power factor.

Technical Parameters

Instructions for Ordering

Due to the different parameters of local power grids and the different power sources of different regions, the equipment requires specific designs based on the actual situation. Please provide the following materials when ordering:

• The customer should provide the model number, compensation capacity, and configuration (one set of compensators per device), as well as the color and type of low-voltage cabinets used.
• If needed, the customer can also request to test the harmonics for the equipment.
• Order quantity, delivery time, shipping method, and transportation details.
• Any other technical requirements.
