GOST 33263-2015 PDF

Full title and description

GOST 33263-2015 — "Разъединители, короткозамыкатели, отделители, заземлители высоковольтные для железнодорожного подвижного состава. Требования безопасности и методы контроля" (English: Disconnectors, short-circuit contactors, separators, high-voltage grounders for railway rolling stock — Safety requirements and methods of control).

Abstract

This interstate (GOST) standard establishes safety requirements, functional and constructional provisions, and methods of inspection and testing for high-voltage disconnectors, short‑circuit contactors, separators and earthing (grounding) devices intended for use on railway rolling stock. It defines essential safety measures, test procedures and acceptance criteria to ensure safe operation, maintenance and verification of these switching and earthing devices in traction and onboard systems.

Scope

The standard applies to high‑voltage switching and earthing devices used on railway rolling stock — specifically disconnectors, short‑circuit contactors, separators (isolating devices) and high‑voltage grounders. It covers safety requirements for design, marking and documentation, environmental and mechanical performance where relevant to safe operation on rolling stock, and prescribes methods of control, inspection and testing to verify conformance. It is intended for equipment that forms part of traction and auxiliary high‑voltage circuits on rail vehicles.

Key topics and requirements

• Definitions and terminology for disconnectors, short‑circuit contactors, separators and earthing devices used on railway vehicles.
• Safety design requirements to prevent inadvertent energization, ensure visible isolation or secure earthing where required, and avoid hazardous conditions for personnel and equipment.
• Mechanical and electrical performance limits relevant to traction applications (e.g., dielectric clearances, rated voltages/currents, endurance and contact design considerations).
• Environmental, vibration and electromagnetic considerations appropriate for rolling stock operation and maintenance conditions.
• Marking, documentation, operating instructions and maintenance requirements to ensure safe installation and servicing.
• Specified test methods and acceptance criteria for type tests, routine tests and inspection to demonstrate compliance (functional tests, dielectric tests, mechanical operation tests, earthing continuity checks, etc.).

Typical use and users

Primary users include railway rolling stock manufacturers and designers, traction equipment suppliers, maintenance and overhaul organizations, testing and certification laboratories, and regulatory bodies responsible for railway vehicle safety. The standard is used when specifying, producing, testing, installing and maintaining high‑voltage switching and earthing devices on locomotives, EMUs, DMUs and other rail vehicles. It also informs procurement specifications and conformity assessment for components intended for onboard traction systems.
