Description

Boards of uninterruptible power supply are intended for reception and distribution of the electric power of 380/220 V to consumers of special group of the first category of power supply from three independent sources of power supply (two main and one reserve).

Boards of uninterruptible power supply are intended for operation in the heated rooms with natural ventilation at the ambient temperature of (5-40) °C, a climatic modification of UHL 4.2 according to GOST 15150.

Environment should not contain chemically active, vzryvo-and flammable vapors and dust. Rated currents and the number of linear automatic machines are defined at the order by requirements of the customer or design decisions.

Boards are made in floor execution with the lower cable connection. Degree of protection is not lower than IP-42 in accordance with GOST 1425 - 80.

Boards are issued in several executions differing in rated current of introduction and section automatic machines, contactors and quantity of sections:

  • ShchGP-2 - five-section on rated current 250 And (ASKI.674521.001);
  • ShchGP-4 - five-section on rated current of 400 And (ASKI.674521.001-01);
  • ShchGP-6/5-five-section on rated current of 630 And (ASKI.674521.001-02);

Boards of uninterruptible power supply provide:

- automatic switching of load from the refused main input of another (serviceable) and giving of command for start of the diesel generator with the subsequent switching of the specified load of reserve input on readiness of the diesel generator;

- switching of load from the diesel generator of earlier refused input at restoration on it rated voltage with a simultaneous parcel of a signal on a diesel generator stop;

- switching of load from the diesel generator of correct input at the failure of the diesel generator which arose until restoration of rated voltage on the refused input;

- switching of load from correct input of earlier refused input at restoration on it rated voltage;

- switching of load of both tires of the diesel generator working as a reserve source at their refusal at different times;

- formation of signals of board operating modes for system of remote control;

- return of the scheme of power supply to an initial state at restoration of rated voltage on both inputs.
