liability. The reliability is refers to the protection to be supposed to move time the body should act not when the movement should reliable not reliability is to the relay protection installment performance most basic request. (2) selectivity. The selectivity is refers first by the breakdown equipment logical 39。 OR39。 3 circuit itself protection excision breakdown, when the breakdown equipment logical 39。 OR39。 circuit itself protection or the circuit breaker resist moves, only then allows by the neighboring equipment to protect, the line protection or the circuit breaker malfunction protection excision order to guarantee has in the coordinate request protection and the identical protection has the coordinate request two parts (for example start and trip part or block system and movement part) the selectivity to the neighboring equipment and the line, its sensitivity coefficient and the operating time, should coordinate mutually in the ordinary circumstances. (3) sensitivity. The sensitivity is refers when the equipment logical 39。 OR39。 circuit occurs by the extent of protection in the metallicity short circuit, the protective device should have the essential sensitivity coefficient, each kind of protection smallest sensitivity coefficient has the specific stipulation in the and sensitive request, through relay protection installation realization. (4) speed. The speed is refers to the protective device to be supposed to excise the short circuit breakdown as soon as possible, its date enhances the system stability, reduces the breakdown equipment and the line damage degree, reduces the breakdown to affect the scope, enhances automatic switches on again with the emergency power supply or the emergency apparatus automatic investment effect and so on. Third, relay protection in 11OKV power supply system Chen Ai function 1. The guarantee continues the electricity system the reliability is plays the relay protection installment role the premise. Continues the electricity system the reliability is plays the relay protection installment role the speaking the relay protection reliability mainly by the disposition reasonable, the quality and the technical performance fine relay protection installment。
