1 Overview

1.1 Scope This standard applies to utility and industrial power distribution systems used in load switch includes a switch disconnectors and current-limiting fuses combination of features Three-pole unit, designed to have. --- Switching capacity. rated recovery voltage, up to and including breaking rated short-circuit breaking current of any current; --- Closing capacity. at rated voltage Closing rated short circuit breaking current applies. This standard does not apply to the motor circuit fuse - breaker, fuse - contactor combinations, or contains a single capacitor bank Load switch combined electrical apparatus. This standard, a "combination" means a combination of each electrical element forming a functional component. A formula for setting the load switch And to jointly shape a formula to determine the fuse of a type of combination units. In fact, different types of load switch fuse combination and one can give a series of combination units with different characteristics, in particular, The rated current. Furthermore, for maintenance purposes, the user should know and be able to type a load switch fuse combination without Impact on the standard of compliance, but also clear the corresponding characteristic combination of such appliances. Load switch - fuse combination by model number and the range of options is determined by the manufacturer of fuses (the so-called "reference Fuse List ") to determine. Conforming to this standard a given combination of electrical means using any alternative electrical fuses for each combination Device can prove compliance with this standard. Load combination of electrical fuses is to increase the short-circuit rating, and short-circuit ratings than when alone with a load switch. Secure Loaded striker, both for the operation of three-phase rely fuse load switch automatically separated, but also in the fault current is greater than the minimum melting current, small To fuse the correct operation of the minimum breaking current. In addition to the fuse striker, the combination of electrical overcurrent release can be installed in parallel or off Buckle device. Note 1. This standard, when the text does not cause the total semantic confusion, "fuse" could refer to the fuse or the fuse. Note 2. This standard, when the text does not cause semantic confusion, "load switch - fuse combinations" and "combinations" refers to "high voltage AC load opening Off - fuse combinations. " This standard applies to the frequency of 50Hz, and above the nominal voltage 3kV, 35kV and below the three-phase AC system, indoors or outdoors The combination of electrical installation. Fuses should comply with GB 15166.2. Load switch, including their specific operating mechanism, taking into account the effect of limiting fuses, in addition to short-term and short-circuit current requirements, should In line with GB 3804. Become an integral part of the combination of electrical grounding switch should comply with GB 1985. 1.2 Normative references The following documents contain provisions which, through reference in this standard and become the standard terms.
