Description
Reactive power compensation units (UKRM) are designed for automatic control of the power factor (cos φ) of electrical installations of industrial enterprises and distribution networks with voltage up to 0.69 kV and 50 Hz. Capacitor units provide a given cos φ during periods of maximum and minimum loads.
Condensing units are designed for operation in closed industrial premises in climatic design and location category U4.

Condensing units UKRM-0.4 allow maintaining the value of the power factor required for the consumer both in automatic and manual modes within 0.8 ÷ 1 by connecting / disconnecting stages of capacitor banks. Monitor the value of the power factor cos φ. Reduce the overall cost of electricity, as well as improve its quality directly in the networks of the enterprise. Increase the service life of the elements of the distribution network by reducing their load.
The UKRM units are mounted in one-sided service floor cabinets, consisting of one or two sections of the same size and design, and are built according to a modular principle. Capacitors, fuses, switching and measuring equipment are installed inside the UKRM case. The front panel contains the controller (reactive power regulator, switch handle and ammeter. Supply and outgoing lines can be located at the bottom and top of the cabinet.
An external current transformer is required for the operation of the UKRM-0.4 controlled installation. The parameters of the current transformer are selected by the customer based on the maximum current flowing through the cable at the point of measurement.
Structural design
The UKRM case is a metal cabinet of the required IP classification. The overall dimensions and design of the cabinet are determined by the customer's requirements, operating conditions, as well as the equipment placed inside. The manufacturing process of the cabinet begins with the design department, then the drawings are sent to the laser cutting workshop, where future body parts are cut on sheet metal. Upon completion of cutting, the workpieces are sent to the bending machine, then welding and surface preparation for powder painting are performed. The thickness of the metal of the body parts varies from 1 to 3 mm.
Environmental durability requirements
ShO-70 are operated in the electrical equipment rooms at any time in a 24-hour period in all weather and seasons, and have the following resistance characteristics against environmental factors:
- ambient air temperature – from -25 to +40°С;
- elevation above the sea level – 1000 m, max.;
- relative air humidity – 75 % at temperature of +15°С;
- atmospheric pressure – from 86.6 to 106.7 kPa;
- atmosphere type as per GOST 15150 – II (industrial);
- environment – non-explosive, free of explosive dust and aggressive gases which concentrations can destroy metals and insulation;
- seismic impact resistance as per GOST 17516.1 – up to 9 points on MSK-64 scale.
Transportation of equipment
By default, ShO-70 are packed into bubble wrap. Special heat-shrink tape is used if required.
ShO-70 are transported as a separate cabinets or transport blocks.
ShO-70 are transported:
- by railroad transport;
- by vehicular transport;
- by river transport.
