ShchO-70 series panels
Panels of switchboards of the ShchO-70 series are intended for completing of the distributing devices of 380/220B of three-phase alternating current with a frequency of 50 Hz with a glukhozazemlenny neutral serving for reception, distribution of electric energy of three-phase alternating current and protection of the departing lines against overloads and currents of short circuit.
The boards of the ShchO-70 series completed from introduction, linear, section and face panels are established in electrorooms and are served from the forward party.
Types of climatic modifications of the ShchO-70 panels — OUSE iUHL4 in accordance with GOST 15150 and GOST 15543, ambient temperature are from-25 With to +40 C, height above sea level no more than 1000 m. The ShchO 70 panels are not intended for work in the environment which is exposed to the strengthened pollution, effect of the gases, evaporations and chemical deposits harmful to isolation and also in the environment dangerous concerning explosion and the fire.
Panels are manufactured with the combined tires having electrodynamic firmness (amplitude value):
- for completing of boards to 630 kVA — 30 kA (ShchO70-1UZ);
- for completing of boards over 630 kVA — 50 kA (ShchO70-2UZ, ShchO70-ZUZ).
On panels both cable, and tire inputs are provided.
Structure of a symbol:
The ShchO-70 panel — X 1 — X 2 — X3, where:
X1 - Model height option;
X2 - Conditional number of the scheme;
X3 - Type of a climatic modification.
Key technical parameters of the ShchO panels:
Overall and adjusting dimensions:
- height of panels:
- option 1 — 2000 mm;
- option 2 — 2200 mm.
- width of panels on a facade:
The ShchO-70 panels are subdivided on:
The ShchO-70 panels are introduction. On panels the switching and protective equipment of input with three transformers of current, three ampermeters and one voltmeter is installed, and also the current transformer on a zero conclusion from the power transformer for protection against short circuits on the earth can be installed. Inputs are carried out by knife switches, automatic switches;
For panels with automatic switches VA53, VA55, E25S switches are used. Between automatic switches and combined tires the unipolar disconnectors operated by a bar are installed. Current transformers in these panels for convenience of service are located between the switch and the disconnector. Between input and the automatic switch there are no disconnectors as at repair of the switch the power transformer can be switched-off from the highest tension. Panels with knife switches are completed with knife switches on 600 A with safety locks and on 1000 A — without safety locks.
Panels provide cable and tire inputs. Introduction panels can be completed with an account guard with counters of active and jet energy at the instruction in the questionnaire.
The ShchO-70 panels are linear. Are completed with knife switches with safety locks, automatic BA51, BA53, BA55 and AE2050 switches. The devices used in panels, forward accession. Thanks to existence between the switch and combined tires of disconnectors with popolyusny otklyucheniyemshtangy safe survey of the panel, repair and protection of switches are possible. Panels with vyklyuchatelyamimonut to be made also without disconnectors
The ShchO-70 panels are section. Are intended for sectioning of inputs when each of sections normally receives power supply from the separate transformer or input. By means of these panels distributing devices of two-transformer substations are completed.
Section panels can be executed on knife switches, automatic switches. On knife switches panels on 600 and 1000 A. Upravleniye' currents are carried out by knife switches of section panels it is exercised of the central lever drive from the front party of the panel. On automatic switches panels on 400, 1000 and 1500 A are carried out. Disconnectors on both sides of the switch are installed in section panels with automatic switches.
The ShchO-70 panels are introduction and linear. On panels the equipment of input, distribution of the electric power the protection equipment, measuring devices is installed. On input knife switches on 600 A with safety locks or on 1000 A without safety locks are established. On the departing lines knife switches with safety locks on 100, 250 and 400 are established And.
The ShchO-70 panels are introduction and section. The equipment of inputs and their sectioning is installed on panels. As introduction devices knife switches on 600 A with safety locks or on 1000 A without safety locks, as the section device — a knife switch on currents 400 and 600 are used And.
The ShchO-70 panels with the AVR equipment. Are intended for two-transformer substations in which it is necessary to provide automatic inclusion of a reserve. It is recommended to establish them between introduction and section panels of the distributing device.
ShchO-70 panels of dispatching management of street lighting. Are completed with the equipment of management and protection of lines of street lighting. It is recommended to establish them extreme in a row the distributing device and to give on them power supply from the next panel.
The ShchO-70 panels for drives to disconnectors. Established on a wall, are completed with the voltmeter and three ampermeters which scales have to be stipulated in the questionnaire. It is possible to install PR-10 and PR-3 drives which are ordered together with the disconnector in the panel and are not included in the package of delivery of the panel.
The ShchO-70 panels are face. Serve for closing of a switchboard from end faces.
Is included in the package of delivery:
- the ShchO-70 panels with the equipment and devices of the main chains according to the order;
- tire bridges (if are stipulated in the order);
- spare parts and accessories according to the specification to order;
- operational documents in one copy.
Have to enter the volume of operational documents:
- the passport of the ShchO-70 panel or of a set of the ShchO-70 panels entering the order;
- technical specification and maintenance instruction of the ShchO-70 panels;
- technical specifications and maintenance instructions and passports of the main components on which delivery of these documents complete with products is provided by manufacturer.
The type of execution of the ShchO-70 panels is defined by the concrete scheme of the main chain and nominal parameters of the built-in devices.
Data necessary for the order:
The main document which is necessary for the correct registration of the order is the questionnaire in which data on each panel are specified. The questionnaire is filled in with the customer (the design organization) and coordinated with the manufacturer.
The following data are specified in the questionnaire:
On each panel which is a part of the order:
- number of the scheme of execution of the main chains;
- purpose of the panel;
- rated current of the panel;
- brand, section and quantity of suitable cables;
- other data necessary for the correct implementation of the order.
The order is taken to execution only after coordination with manufacturer of the questionnaire taking into account all possible changes and additions.
All questions connected with production of panels with non-standard decisions (schemes, layout decisions etc.), have to be stipulated in the separate document and are coordinated with the manufacturer
Term of production of panels: from 10 working days.
