Specific embodiment
To keep the structure and advantage of the utility model clearer, make below in conjunction with structure of the attached drawing to the utility model
It is further described through.
Embodiment one
The utility model provides long-range discharge controller, and the controller includes:
The anode of battery group, battery group is connected to charging circuit KM+, electric power storage through normally closed switch KN2, fuse FU2
The cathode of pond group is connected to charging circuit KM- through fuse FU2, switch DK2, the anode of battery group also through breaker DK1 and
Normal open switch contact KN1 is connected to one end of discharge module FD, and the cathode of battery group is also touched through breaker DK1 and normal open switch
Point KN1 is connected to the other end of discharge module FD, and normally closed switch contact KN2 and normally closed switch contact KN3 are in parallel, in normally closed switch
The both ends KN3 are also parallel with diode V;
The first tie point is equipped between breaker DK1 and normal open switch, in the cathode and discharge module FD of battery group
The other end between be equipped with the second tie point, the first tie point, the second tie point are connected to Switching Power Supply through fuse FU1;
The control circuit for being responsible for remotely controlling is equipped between the positive and negative anodes of Switching Power Supply.The control circuit includes parallel connection
Six branches;
Wherein, the first branch includes the relay and switch M5 for remotely being controlled the electric discharge of battery group, after
Coil K1 in electric appliance is controlled by instruction remote command MRTU-DO1 closure, and the coil K2 in relay is controlled by the long-range life of instruction
MRTU-DO2 is enabled to be closed;

Specifically, major loop is mainly by normally closed contactor KN2 and KN3, normally open contactor KN1, diode V, breaker DK1
Composition;Control loop is by fuse FU1, Switching Power Supply, relay and temperature detect switch (TDS), indicator lamp groups at.
When battery group is in charged state, KN2 and KN3 closure, KN1 are disconnected, and diode is in off state.
When needing to carry out the operation of local manual discharge: being shorted MRTU-DO1 and MRTU-DO2 terminal respectively;Operate DK1
Closure, at this point, K1 and K2 coil are powered, K3 is closed the switch, and KM1, KM2, KM3 coil are powered, therefore KM1 is closed contact in major loop
It closes, KM2 and the contact KM3 disconnect;Star t-up discharge module can carry out manual discharge.

And it is self-locking, normally-closed contact K3 is disconnected, so that relay coil K1 and K2 is powered off, so that KM1, KM2, KM3 coil blackout, because
In this major loop, the contact KN1 is disconnected, KN2, KN3 contact closure, disconnects discharge loop, the outer current supply circuit of automatic closed pair automatically.
To avoid diode longtime running, also avoid further proceeding with unnecessary electric discharge in battery group supplying power for outside.It is tying
After beam exchanges power loss accident treatment, it is only necessary to disconnect a breaker DK1, control loop can be completed and reset original state.
Current inductor realization also can be used in temperature detect switch (TDS) WT in this product, and current inductor here incudes
The electric current for detecting diode outgoing line position, when diode, which has, flows through a constant current, one closure contact of movement output.
This product is in advantage structurally and functionally:
1) control of discharge modularization, wiring are concise;
