Contact connections of wires in a low-voltage equipment must conform to the requirements GOST 10434-82.
Editing of wires - buildings.
For editing a copper, solid wire must be used, except for connections with mobile elements for which a wire must be flexible.
Section of wires concordantly RSEI p.3. 4.12, but no less:
Wires must not have a pull.
The electric editing must not hinder access to the removable and managed elements for examination, verification and their replacement.
The ends of free wires must be isolated.
All wires and apparatus must have marking, proper indicated on an of principle chart and chart of connections.
Contact connections of wires in LCD must correspond GOST 10434-82.
Requirement to the rows of clamps
These requirements do not spread on power clamps.
The rows of clamps must be set apeak on the assembling side of closet and disposed on the left and right side-frames.
Placing of clamps and apparatus on panels must provide comfortable access to the clamp of the second chains on any terminal.
Clamps must have connection "screw-screw" for the nominal section of explorers to 4 mm with a maximal loading current no less than 16 A and by nominal tension no less than 400 V.
Clamps must take from measurings clamp with release, communicating terminals and terminals with slide-type disconnectors.
Communicating clamps must be set in the chains of permanent and variable tension, operations in which will be executed an operative personnel with the use of separate make-and-break devices (switches, proof-of-concept blocks, sockets etc.). Number them determined a project for every panel concretely.
Communicating clamps with dis-connector must be set in the chains of direct-current, operations in which will be executed a relay personnel (chains of signaling, chains to the recorder of emergency events, chains of starting of commands of teleacceleration, prohibition ARI etc.). Number them determined a project for every panel concretely.
Clamps with slide-type release must be set in the measuring chains of TC (transformator of current) and TT (transformator of tension).
Contacts and all belongings of current-carrying 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 nearby clamps.
In a complete set deliveries must be bridges, foreseen a chart (by a working document).
Class of inflammability for all types clamps V0 on the standard of Ul94.
Basic descriptions of clamps must conform to the requirements of standard of IEC 7-7.
Requirements to the make-and-break switchgears
· The switches set in closets must provide reliable commutation of currents from 2 to 1000 mA at nominal tension 220 V. · Transitional resistance of contacts make-and-break devices must be no more than 0,002 Ohm. · The wearproofness is more than 25000 cycles. · Durability of isolation - 1000 V, during 1 minute.
Requirement to editing of apparatus
All make-and-break devices, proof-of-concept blocks, relays must be disposed on the external facial surface of closet.
Microprocessor devices of defense in a closet it is necessary to place at level, comfortable for service (height 1,4 - 1,7 m from the level of floor).
For fastening apparatuses must be used assembling laths.
Resistors, diodes, condensers must take place from the back (editing) side of plane for setting of apparatus.
Every vehicle must have marking in accordance with denotation of vehicle on an of principle chart.
Inscriptions of make-and-break devices, alarm apparatus etc. must be disposed under a device in a scope for inscription. Inscription must include marking and setting of vehicle.
Requirements to reliability
Reliability of low-voltage complete equipment indexes must correspond GOST 27.003-90, GOST 20.39.312-85.
Requirements to fire safety
The construction of closet must correspond the terms of fire safety in accordance with GOST 12.1.004-91.
Kitting
In the complete set of delivery LCD must enter:
· closet with the internal editing of all necessary elements, including microprocessor device; · standard complete set of spare parts, recommended a factory-manufacturer; · operating document on ukraine /russian language.
Nomenclature and amount supplied with the equipment of the systems electric defense and automation of substation 330 kV «Zhovtneva»
Tables of technical information for the system of relay protection and automation
Generals The tables of technical requirements presented below must be fully filled Participant of auctions and presented together with the tender offering to Customer.
Descriptions and guarantees, plugged in these tables, must become part of Contract and to be obligatory for implementation. Without a writing concordance with Customer of deviation from requirements shut out.
The participant of auctions must present all necessary catalogues and information for complete description of the offered equipment, mechanisms, adaptations, devices and materials which will be used by him for implementation build of assembling and starting-up and adjustment works.
The participant of auctions carries responsibility for any errors, disparities or omissions in the descriptions offered to them in the tables of technical requirements.
The participants of auctions must understand that incomplete answers for put question mean disparity the requirements of Customer (to the requirements of Contract), and the result of it can be a waiver of Customer of such tender suggestions.
The participants of auctions must confirm in the tender suggestion, whether their offering to the requirements of Customer corresponds in (without some rejections) general or not.
If there are rejections or differences, they must be described and explained for every position of tables in a column «Note» or on a separate sheet.
Terminology Next terminology is used in this document (list not exhaustive):
