Technical Indicators Of The Product

Working Principle Of The Entire Machine

The product consists of inteligent components,zero switching switches, current sampling, temperature sampling, dny series reactors, and low-voltage filtering power capacitors. The following fiqure is the working principle block diagram of the split phase compensation method product in the product series.

Action Principle Of Each Component

Intelligent components

Use wide-temperature industrial-grade electronic components, adapt to harsh environments,and run stably for a long time.

Synchronous switch

Developed independently by integrating features of mechanical contactors, etc., controls mechanical contacts with microelectronic technology to achieve zero-crossing switching, avoiding inrush current impact, reducing loss and extending capacitor life.

Dry-type series reactor

Made of high-flux imported materials, light, small, low-loss, with low temperature rise and noise; built-in thermal relay sends signal when over-temperature.

Mini current sampling transformer

With permalloy core,high linearity and good frequency characteristics, ensuring accurate and stable current and protection.

Quick circuit breaker

Molded case type, disconnects within 100ms at 10 times rated current, serving as total protection and power switch.

Appearance And Installation Dimensions

Note: 1. The standard reactance rates for the above products are P7 and P14, and other reactance rates can be selected according to customer needs.

2. The table only ists commonly used product models and specifications, and other models can be consulted for details.
3. The rated voltage of the P14 co compensation type product is 525V, and the rated voltage of the sub compensation type product is 300V.

Simple Anti Harmonic Intelligent Capacitor

Note: The width and depth of smart capacitors are consistent among diferent capacities, but there are only diferences in height.

Electrical Wiring Requirements

The production of the power cord is as shown in the figure: the power cord must be tightened with screws, and the power cord must be forcefuly pulled to prove that it is very firm. Otherwise, it will cause excessive heating in the area and damage the product.

Controller and product wiring: The secondary wiring needs to be connected from the first or last external 485 port in the cabinet product to the corresponding controller 485 port, As shown in the figure:

When there is an external indicator light, select the appropriate voltage level status indicator light based on the capacitor model, and the indicator light for the co compensating capacitor is 380V: The indicator light of the compensating capacitor is220V, and terminal 5 of the compensating capacitor is connected to one indicator light. The other end of the light must be connected to the power supply UB; Terminals 34 and 5of the compensating capacitor must be connected to the indicator light respectively, and the other end of the light must be connected to the neutral line UN (product indicator lights cannot be short circuited or shared).
