Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that protection scope of the present invention is not by the restriction of detailed description of the invention.
The high-tension distribution box monitoring device of the present invention is by design simulation circuit, the control signal controlling to replace controller is switched on-off by three, whether can normally, accurately light according to display lamp and judge that whether correct the inside wire harness of high-tension distribution box connect and relay whether normal operation, high-tension distribution box need not be opened, but connect by designing the air plug of Corresponding matching on this device, it is achieved monitoring quick, accurate, safe and efficient.In this device mainly monitoring high-tension distribution box, whether anode relay, pre-charge-relay and negative terminal relay whether normal operation and corresponding linear speed connect correct.
As shown in Figure 1, high-tension distribution box to be monitored powers on safely principally for power assembly, it is realized by indoor design preliminary filling loop 50 that safety powers on, and preliminary filling loop 50 includes pre-charge-relay 20, preliminary filling resistance 30, inverter and negative terminal relay 40, and it forms series loop with high-tension battery.The operation principle of high-tension distribution box is, first, by car load high-tension electricity automatic breaking controller ADM(AutomaticDisconnectingModule) pre-charge-relay 20 within distribution control box, negative terminal relay 40 close, reach after ADM inner setting value until preliminary filling loop voltage, precharge completes, and pre-charge-relay 20 disconnects, now, anode relay 10 closes, and completes normal power up.Symbol implication in Fig. 1 is shown in following table:
As in figure 2 it is shown, first switch circuit the 202, first indicator place, K1 place circuit 201, second switch place circuit the 205, second indicator place circuit 204 and the 3rd switch place circuit 203 pass through air plug (unmarked in figure) with corresponding negative terminal control relay circuit 102, negative terminal relay place circuit 101, anode control relay circuit 105, anode relay place circuit 104 and pre-charge-relay control circuit 103 connects formation corresponding circuit.Specifically, first indicator place circuit 201 and the first switch K1 place circuit 202 constitute negative terminal relay 40 observation circuit, second indicator place circuit 204 constitutes anode relay 10 observation circuit with second switch place circuit 205, and the 3rd switch place circuit 203 and the second indicator place circuit 204 constitute pre-charge-relay 20 observation circuit.Above-mentioned first indicator is the first display lamp, and the second indicator is the second display lamp.
Concrete monitoring determination methods is as follows:
One, switching K1 by first and control the control coil of negative terminal relay, if circuit is correct and negative terminal relay is working properly, display lamp L1 lights；
Two, controlled the control coil of anode relay by second switch K2, if circuit is correct and anode relay is working properly, display lamp L2 lights；
Three, switching K3 by the 3rd and control the control coil of pre-charge-relay, if circuit is correct working properly with pre-charge-relay, display lamp L2 lights, but the brightness that its brightness is than L2 when monitoring anode relay is weak, because there being the reason of preliminary filling resistance.
As it is shown on figure 3, control negative terminal relay by the first switch K1 concrete monitoring principle is described.When first switchs K1 Guan Bi, negative terminal control relay circuit constitutes complete loops (in figure, light color arrow represents current direction), control coil within negative terminal relay has electric current to pass through, the magnetic force produced is by the switch adhesive of negative terminal relay, now display lamp L1 place circuit has constituted loop (in figure, dark arrow represents the current direction in this loop), and L1 display lamp is lighted.In K1 Guan Bi situation, if L1 lights, then illustrate that circuit and negative terminal relay are all normal, if L1 does not work, then circuit or relay existing problems are described.
The specific embodiments of the invention that are only disclosed above, but, the present invention is not limited to this, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
