JB/T 7116-2007 (English Version) PDF

Scope: This standard specifies the basic requirements for a vacuum type integrated starter (hereinafter referred to as the starter) that combines a vacuum contactor with a rated operating voltage of 6kV and below, a current-limiting fuse and an integrated protection relay, including the characteristics of the starter, which should be followed The relevant conditions, structure and insulation performance, as well as the test methods to verify that the starter meets these requirements, and stipulate the main technical information and parameters that the manufacturer should provide to the user. This standard applies to starters in non-exposed devices whose main circuit is AC 5OHZ and the rated operating voltage does not exceed 6kV. a) Single-input single-output direct starter equipped with overload and short-circuit protection (main busbar or cable); b) Single-input multiple-output direct starter equipped with overload and short-circuit protection (main busbar or cable).
