Low-voltage switchgears

A broad range of NIPOM products grants the possibility of choosing an optimum solution allowing to reduce expenses
on use and to increase reliability of power supply to the facility.

EXAMPLES OF LOW-VOLTAGE  switchgears-BASED SOLUTIONS

AGGREGATE BOARD
OF CONTROL STATIONS

Application

The board is intended to receive and to distribute the electricity with voltage 0.4 kV AC to consumers, as well as to serve as a control station for 1st category electric loads of process units (including gas and oil processing equipment).

Functions

  • Manual, remote and automatic control of the power-consuming units, including: fan and valve motors, pumps, heaters, power instrumentation, emergency protection, and lighting;
  • Thermal and current microprocessor-based protection of power consuming units;
  • Monitoring of parameters, light indication of state of power supply system and apparatus;
  • Sending signals about the status of electrical installation to the site control system;
  • Power automatic switch on the basis of a programmable relay/controller.

LOW-VOLTAGE  SWITCHGEARS FOR GAS AND LIQUID AIR COOLING UNITS

Application

Low-voltage switchgears is intended to receive and to distribute the electricity, and to manage the motors of gas and liquid air cooling units.

Functions

  • Continuous monitoring and display of motor current;
  • Digital protection of motor from skewing, loss and incorrect phase sequence, exceed of starting current tolerances and intervals between starts;
  • Process and commercial metering of electricity;
  • Protection of power transformer on the basis of temperature and oil pressure data.

GENERAL BOARD OF CONTROL STATIONS

Application

The board is intended to receive and to distribute the electricity with voltage 0.4 kV AC to consumers, as well as to serve as a control station for 1st category electric loads of general-purpose and auxiliary systems of buildings and construction of engineering and manufacturing facilities.

Functions

  • Manual, remote and automatic control of the power-consuming units, including: fan and valve motors, pumps, heaters, power instrumentation, emergency protection, and lighting;
  • Prompt switching on/ switching off of power-consuming units;
  • Thermal and current microprocessor-based protection of power-consuming units;
  • Monitoring of parameters, light indication of state of the power supply system and apparatus;
  • Sending signals about the status of electrical installation to the site control system;
  • Power automatic switch on the basis of a programmable relay/controller or the standby power switch in the manual mode.

FIRE-RESISTANT CABINETS OF SEISMIC EXECUTION

Application

Fire-resistant cabinets of seismic execution are intended to install the low-voltage equipment.
