Compared with prior art, advantage of the present invention:
1, provide one to meet electric power system to administrative staff and be accustomed to Chinese method of operation: but needs when closing a floodgate administrative staff send a note earlier and " close in advance "; After receiving the affirmation order; Redispatch one " combined floodgate " instruction, protective device just can have been controlled breaker closing; Inquire about the operating condition of current circuit when needs, only need input " query State ", deciliter state of the electric current and voltage circuit breaker that protective device can monitor current protective device sends on the mobile phone of personnel query together.
2, protective device has the automatic correcting time function: when protective device receives correct note; Whether the time that can detect protective device automatically is consistent with the time of note; Will be if inconsistent according to the time automatic correcting time of note, when perhaps receiving school, " during the school " instruction back.If when protective device is not carried out the school, when the protection of many protective devices is moved simultaneously, and the time of protective device is not right, with making administrative staff be hard to tell the precedence relationship of protection action, brings difficulty to accident analysis.
3, protective device only surpasses certain limit in the electric current and voltage fluctuation, when opening into amount generation displacement, just initiatively goes up time, title, the operating value of sending out analog quantity, on off state and the incident of generation; But not periodically sending information, periodically sending information can be issued some useless information of administrative staff, can not in time send information when perhaps fault being arranged.
4, administrative staff can inquire about the state that protective device detects: administrative staff oneself at any time can be through sending the information that query statement is inquired about oneself to be needed.
5, parameter modification authority: each protective device can be imported 5 administrative staff's number, first advanced level user, and this user can have inquiry, revise definite value parameter, divide-shut brake function, and other 4 domestic consumers only have inquiry and divide-shut brake function.
6, protective device automatic dialing: when important load breaks down; Protective device is put through first administrative staff's number automatically; If do not answer after 3 times the number of putting through second administrative staff redialing automatically, till having administrative staff to answer or having redialed last administrative staff's number 3 times.
