3. Terminators of overstrain

Terminators of overstrains (TOO) 330 kV, 110 kV - single-phase, outward setting, with a polymeric isolation.

TOO must be set on isolatings supports, and also must be supplied screening rings for protecting from koronirovaniya and providing of equitability tension on all length of terminator from top to bottom.

The terminators of overstrains must be manned the system of monitoring of the state with integration of it in ACS substations.

Every terminator of overstrains must have a meter of number of wearing-outs and sensor of current of loss, which is fastened directly on support.

The basic requirements to to TOO must be certain concordantly GOST 52725-2007 «Terminators of overstrains nonlinear for electrical installation of alternating current tension from 3 to 750 kV».

Device for monitoring of the state TOO must be completed transceivers (by the receivers of information from touch-controls). Technical descriptions can be specified at signing of agreement of supplying to the products.

System of monitoring of the state must have TOO, but unreserved, by next functions:

• registration of wearing-outs is TOO;

• fixing of time of wearing-out;

• fixing of value of impulse of current of passing through TOO.

• measuring of current of loss.

Other parameters, required Customer, are indicated in "Table of technical requirements".

4. Shield of own needs 0,4 kV

The shield of own needs must have two inputs with circuit breakers, sectional switch. Every section must have no less one closet of outgoing lines. Outgoing lines are on the defensive circuit breakers.

The circuit breakers of inputs and sectional switch must have remote and local control.

The circuit breakers of outgoing lines can also have remote and local control.

Climatic execution and category of placing of UKHl4 for GOST 15150-89 and GOST 15543.1-89. Degrees of defence of Ip40 on IEC 529 (GOST 14254-80).

Electric descriptions of closets must correspond GOST 22789-94.

A shield must be equipped all wiring, terminals, alarm relays, by lamps et al needed by accessories.

The electric editing must not hinder access to the removable and managed elements for examination, verification and their replacement.

All wires and apparatus must have marking, proper indicated on an of principle chart and chart of connections.

Contacts and all belongings of tokoveduschikh chains must be protected from a casual touch in obedience to the standard of safety.

The construction of terminals must eliminate possibility of casual shorting of nearby clamps.

On the inputs of feed 0,4 kV shield to foresee setting of electricity supply meter of class of exactness of «1», with two interfaces of RS 232 and RS 485 and additional feed for ASCB.

A shield must be equipped the elements of the controlled from distance control and management, and also inspector of management introductory and sectional automats, control of electric parameters with possibility of reception and delivery of signals in the system to ACS.

Possibility of delivery of signals must be foreseen about the state of automats (included, power-off) and position of the management (local and distance) key, and also signal about work of ALT in the system to ACS.

In the complete set of supplying with a shield must enter:

• closets with the internal editing of all necessary elements.

• standard complete set of spare parts, recommended a factory-manufacturer;

• operating document on Ukrainian/Russian language.

Other parameters, required Customer, are indicated in "Table of technical requirements".
