Description

BBP-10-31,5 series. Switches with the built-in spring and motor drive are intended for switching of electric chains at normal and emergency operation in networks of trekhfazkny alternating current with the isolated neutral of the frequency of 50 Hz with a rated voltage of 10 quarter. Are established in cases of complete distributing devices (CREWE and KSO), and also are used for replacement of low-oil and electromagnetic switches.

The spring and motor mechanism without additional power supply can make the full automatic repeated inclusion (ARI), and in a "emergency" case there is a possibility of inclusion manually, at total absence of expeditious food.

Application advantages

The main advantages of vacuum BBP-10-31,5 switches defining their broad application:

• Full vzryvo-both fire safety and a possibility of work in aggressive environments;

• Wide range of ambient temperatures in which work of VDK and the drive is possible;

• The increased resistance to shock and vibration loadings owing to the small mass and a compact design of the device;

• Any working situation and small dimensions that allows to create various configurations of distributing devices including cases with several switches at their two-three-storied arrangement;

• The noiselessness, purity, convenience of service caused by lack of emission of oil, gases at shutdown of currents of KZ;

• Lack of environmental pollution;

• High reliability and safety of operation, reduction of time for installation;

• The Malogabaritnost of BBP-10-31,5 allows to build in it any type of switchgears, especially where it is required to provide the first inclusion in the absence of expeditious food and in the absence of additional power supply units.

Execution and completeness

Standard execution of vacuum VVR-10 switches provides the following:

• manual expeditious inclusion and shutdown (that will allow to carry out first "inclusion" without food of operational chains);

• reliable spring and motor drive;

• electric blocking from repeated inclusion;

• mechanical blocking from the wrong functioning of the drive;

• electromagnets of remote expeditious inclusion and shutdown (YAC and YAT);

• the built-in current electromagnets for schemes with a deshuntirovaniye (2 pieces);

• electromagnet of disconnection from the independent power supply (YAV).

• auxiliary block contacts (5 normal opened contacts closed + 6 normal;

• index of position of the switch - "VKL" and "OTKL"

• the mechanical index of provision of a spring of inclusion "Is ready" and "Is not ready";

• mechanical counter of number operation IN

• universal scheme of management of an alternating and direct current;

• a hydraulic damper of shutdown (allows to extinguish excess vibration at the expense of what the resource of operation of the switch increases);

• lack of repair and service during all service life;

• silver covering of current carrying parts

• strengthened, made of heavy-duty polycarbonate, isolation of poles of the switch guarantees lack of breakdowns and a possibility of damage of a vacuum dugogasitelny chamber.

Are included in the basic package: 5 (five) electromagnets of inclusion / shutdown, including:

  • 2 (two) current electromagnets - for schemes with a deshuntirovaniye;
  • 1 (one) electromagnet of shutdown with the independent built-in food (that guarantees to 100% shutdown at any not regular situation).
  • Existence of mechanical inclusion.
  • Existence of the current electromagnets allowing to use schemes with a deshuntirovaniye.
  • Existence of an electromagnet of shutdown with autonomous food that allows to make shutdown at any not regular situation.
  • Use of the relay blocks working on current chains allow to make shutdown without expeditious food.
  • For the VVR-10 switch there is no need for additional power supply units, management, etc. Everything is built in in the uniform case.
