GOST 33798.2-2016 PDF

Full title and description

GOST 33798.2-2016 — "Electric equipment for railway rolling stock. Part 2. Electrotechnical components. General specifications". The standard sets general technical requirements, classification, rated values, test methods and documentation/marking requirements for electrotechnical components used on railway rolling stock (switchgear, relays, resistors, capacitors, fuses, transformers, reactors, connectors, etc.).

Abstract

GOST 33798.2-2016 is a national (interstate) adoption/modification of the international standard IEC 60077-2 (electrotechnical components — general rules). It provides uniform requirements and tests to ensure safe and reliable performance of electrotechnical components in traction, auxiliary and control circuits of rail vehicles under specified operating and environmental conditions. The document supplements part 1 of the series covering general service conditions.

Scope

This standard applies to electrotechnical components intended for installation on railway rolling stock in power circuits, auxiliary circuits and control/indicating circuits. Covered items include switching and control devices irrespective of their actuation (contactors, circuit-breakers rules are covered in related parts), relays, valves, resistors, capacitors, fuses, reactors, chokes, transformers, rectifiers, plug-and-socket connectors and similar components. The standard defines required characteristics, operational/environmental conditions, safety requirements and the test procedures necessary to demonstrate conformity.

Key topics and requirements

• Classification of electrotechnical components for rolling stock (power, control, auxiliary circuits).
• Rated and limiting values (voltages, currents, time constants, power factors) and component categories.
• Short-circuit and withstand requirements: breaking capacity, rated short-time withstand current and critical current ranges.
• Environmental and climatic conditions, mechanical shock and vibration considerations specific to rail applications.
• Test methods for dielectric strength, heating, endurance, short‑circuit performance and other type/acceptance tests.
• Requirements for product information, marking, documentation and instructions for installation, operation and maintenance.
• Safety requirements for insulation, clearances, protective devices and temperature limits of components and enclosures.

Typical use and users

Used by rolling-stock designers and manufacturers, electrical and traction-equipment suppliers, component manufacturers, test laboratories and certification bodies, maintenance organizations and regulatory authorities to specify, design, test and verify electrotechnical components for trains, trams and other railway vehicles.

Related standards

Part of the GOST 33798 series; closely linked with GOST 33798.1 (Part 1 — general service conditions and rules) and other parts that cover specific component types (e.g., AC/DC circuit-breakers, fuses, etc.). The text is based on and cross-references IEC 60077 series (notably IEC 60077‑2). The standard also references protective-degree (IP) standards and environmental test standards used for rolling stock.

Q: What does it cover?

A: It covers classification, rated/limiting values, safety and environmental requirements, type and routine test methods, documentation and marking for components such as contactors, relays, resistors, capacitors, fuses, transformers, reactors, connectors and similar electrotechnical devices used on rail vehicles.

Q: Who typically uses it?

A: Rolling-stock manufacturers, component suppliers, test houses, certifying bodies, maintenance organizations and standards/regulatory authorities involved in railway electrical equipment.

Q: Is it current or superseded?

A: As of its entry into force (01 May 2017) the standard is in force. It is a 2016 edition introduced by Rosstandart order No. 1309‑ст (05 Oct 2016) and remains the applicable GOST part for electrotechnical components unless a later national amendment or replacement has been published. Users should check national catalogues or the issuing body for any amendments or newer editions.

Q: Is it part of a series?

A: Yes — it is Part 2 of the GOST 33798 series on electric equipment for railway rolling stock; other parts cover general service conditions (Part 1) and specific device types (other numbered parts). The series maps to the IEC 60077 family.
