As Fig. 1 to Fig. 3, the embodiment of the present invention provides a kind of sincere intelligent instrument, comprise main circuit, described main circuit is connected with intelligent instrument and control circuit QF, described intelligent instrument is connected with described control circuit QF by three-phase voltage and multiple current transformer LHa-c.
As Fig. 1 to Fig. 3, described intelligent instrument have three-phase voltage interface, multiple current line interface and an electronic type for a long time relay action outlet K1.Described three-phase voltage interface is respectively ua, ub and uc, and described three-phase voltage interface is all connected to main circuit, and connectivity port is X1, X2 and X3, and centre is provided with resistance 1RD, 2RD and 3RD.
As Fig. 1 to Fig. 3, multiple current line interface is corresponding with multiple current transformer to be connected, and in this preferred embodiment, the quantity of described current transformer is three, and the quantity of described current line interface is three groups, and each group current line interface is connected to a current transformer.Described current line interface three components Wei Ia1 and Ia2, Ib1 and Ib2, Ic1 and Ic2.
As Fig. 1 to Fig. 3, described control circuit comprises closing circuit and sub-gate circuit, described closing circuit and described sub-gate circuit are connected in series, and be connected to control power supply XI and N respectively, described closing circuit has the feed motion mechanism that a closing switch HA and main switch therein have, described sub-gate circuit has the separating brake actuating mechanism that a separating brake switch TA and main switch therein have, the action outlet K1 of described electronic type for a long time relay is connected to the both sides of described separating brake switch TA, i.e. two tie points 101 and 105.
Further, a fuse FU is also comprised in described control circuit, for the protection of circuit safety.
As Fig. 1 to Fig. 3, described closing circuit and described sub-gate circuit all have and multiplely connects pressure side, connect pressure side in this preferred embodiment and be divided into two groups, each group is two, marks 1,2 and 3,4 in figure.Closing circuit connect pressure side son between tie point 103 and 102, described closing switch HA is between tie point 101 and 103, and tie point 101 and 102 is connected to control power supply.Sub-gate circuit connect pressure side son between tie point 105 and 102.
Further, described intelligent instrument has RS485 communication interface, represents in figure with A and B.
When electronic type for a long time relay from confirmation is set after, after accumulative timing reaches setting-up time, " normally opened contact " saltus step of electronic type for a long time relay is " normally closed contact ", the tripping operation of the incoming line cabinet master switch of control circuit is disconnected, and, no matter this contact is having under electricity or electroless state, remain unchanged always, only when re-starting " electricity consumption prescriptive jurisdiction information " and arranging, carry out clearing process, this contact just returns to " often opening ", just can carry out next power transmission operation, thus reach the sincere effect of gathering power supply, reduce monetary losses and the pressure of distribution products enterprise.
During concrete use, described sincere intelligent instrument, after working on power, has two menu task options: one, basic information about power; Two, electricity consumption prescriptive jurisdiction information.After entering the first option, can check " voltage ", " electric current " that the basic information about power such as " frequency ", " gaining merit ", " idle ", " harmonic wave ", after entering the second option, needs password input just can open; After the correct password code of input, can carry out the setting of electricity consumption duration, when having mouth mouth mouth sky mouth mouth mouth in arranging, mouth mouth divides, and the longest power-on time can be set to 999 days 999 hours 59 minutes.Such as, according to the purchase order that both sides of supply and demand are signed, arrange this batch facility at powered operation after 6 months, demanding party pays off the remaining payment for goods of 30%, so, supplier technician can according to the agreement of this contract, at the scene during transmission operation, " the electricity consumption prescriptive jurisdiction information " inside sincere intelligent instrument is set to 180 days 12 hours 00 point.When the built-in electronic type of instrument for a long time relay from confirmation is set after, accumulative timing reaches 00 timesharing in 12 hours in 180 days, " normally opened contact " saltus step of electronics for a long time relay is " normally closed contact ", the tripping operation of the incoming line cabinet master switch of control circuit is disconnected, and, no matter this contact is having under electricity or electroless state, remain unchanged always, only when re-starting " electricity consumption prescriptive jurisdiction information " and arranging, carry out clearing process, this contact just returns to " often opening ", just can carry out next power transmission operation, thus reaches the sincere effect of " gathering power supply ".
