HIGH FREQUENCY CONVERTERS - AVPCH
Purpose of the development:
High-frequency converters AVPCH designed for speed control mechanisms
with driven asynchronous motors with squirrel-cage rotor voltage 3 ... 10 kV power
from 400 kW to 12.5 MW.
Recommended application field:
Fields of application:
- Metallurgy;
- Mining;
- Automotive;
- Chemical Industry;
- Oil and gas industry;
- Mechanical Engineering (fans, conveyors);
- Utilities (pumping stations, treatment plants)
Technical characteristic:
The main technical features:
- Soft start and stop the engine with variable speed;
- Infinitely variable speed in a given range;
- Optional - function "bypass" and software "synchronous transfer", provides switching
motor when operating on AVPCH to direct work of the network and vice versa;
- In local mode - set and display the main technological parameters of the drive at
touch-LCD-display, located directly on the power board;
- In remote control - communication with external automatic control system using discrete
or analog signals, or by network communication;
- Diagnosis and indication for possible problems with the entry in the event log.
Advantages over analogues:
The main advantages:
1. Low distortion introduced into the mains supply.
2. Almost sinusoidal output voltage.
3. Optimum power wiring diagram of external connections.
The development stage readiness:
Ready for application
Description of the development:
() AVPCH performed in a "multi-level" converter with integrated terminating multiwinding
power transformer.
AVPCH structure:
- A case of the transformer (PCS);
- A case of force (SHS);
- Control cabinet (SHU).
