The two switches are arranged in a reverse-phase interlocking manner, and when the finger trigger switch is switched off, the response switch is immediately or in delayed disconnection; when the trigger switch is switched off, the response switch is immediately or time-delayed to be switched on. In the present invention, either one of the switch a and the switch B may be a trigger switch.
Generally, for a dc load, the load connection terminal set has 2 terminals, and the output terminal of the load connection terminal set does not necessarily need to be connected with the positive pole, and can also be connected with the negative pole.
In the present invention, the power supply module refers to a functional module, which does not necessarily form an electric circuit when used alone.
Example 1: a power distribution circuit comprises a storage battery, a key load wiring bus WB1, a general load wiring bus WB2, a diode D3, a diode D4, a change-over switch S1, a relay KM2, a time-delay disconnection type time relay KT1 and a relay KM 1.
The positive electrode of the storage battery, the load end of the relay KM1, the general load wiring busbar WB2, the diode D3, and the critical load wiring busbar WB1 are connected in series.
The positive electrode of the storage battery, the load end of the relay KM2 and the key load wiring busbar WB1 are connected in series. The load side switch of relay KM2 forms switch a.
The general load wiring busbar WB2 and the negative electrode of the storage battery form a general load wiring terminal group. The critical load wiring busbar WB2 and the negative electrode of the storage battery form a critical load wiring terminal group.
The change-over switch S1 has a movable contact 1, a fixed contact 2 and a fixed contact 3, the movable contact 1, the fixed contact 2, a coil of the relay KM2, a second current backstop and a storage battery are connected in series, and the movable contact 1, the fixed contact 3, the coil of the time-delay disconnection type time relay KT1 and the storage battery are connected in series. The load end of the time delay disconnection type time relay KT1 is electrically connected with the coil of the relay KM1 in series, and the load end of the relay KM1 forms a switch B. In this embodiment, the relay KM1 is coupled and controlled by a time-delay disconnection-type time relay KT 1. In other embodiments, the load terminal of the time delay disconnection type time relay KT1 may directly replace the load terminal of the relay KM1, so that one relay KM1 may be omitted.
The power distribution circuit of the present invention is preferably installed in aircraft, including ground-based aircraft, submarines. Thus, a spare storage battery can be saved, and corresponding space and weight are saved.
When the switch is used, the movable contact 1 of the switch S1 is connected with the fixed contact 3, the coil of the relay KM2 is powered off, and the load end of the relay KM2 is disconnected. The coil of the time-delay disconnection type time relay KT1 is electrified, the load end of the time-delay disconnection type time relay KT1 is immediately closed, the coil of the relay KM1 is electrified, the load end of the relay KM1 is closed, and the positive electrode current of the storage battery flows to the key load wiring bus WB1 through the general load wiring bus WB2 and the diode D3. The positive and negative poles of the general load mounted on the general load wiring busbar WB2 are connected to the storage battery, and the general load operates. The anode and the cathode of the critical load mounted on the critical load wiring busbar WB1 are connected with the storage battery, and the critical load works. The provision of diode D4 prevents current on the critical load wiring busbar WB1 from passing through diode D4 in reverse to energize the relay KM2 coil even when the stationary contact 2 is abnormally grounded.
In emergency situations, the normal load needs to be deactivated. At this time, the movable contact 1 of the switch S1 was connected to the stationary contact 2, the coil of the relay KM2 was energized, and the load terminal of the relay KM2 was closed. The coil of the time-delay disconnection type time relay KT1 is powered off, the load end of the time-delay disconnection type time relay KT1 is in time-delay disconnection, before the load end of the time-delay disconnection type time relay KT1 is not disconnected, the coil of the relay KM1 is still in a power-on state, the load end of the relay KM1 is still in a closed state, and the positive electrode current of the storage battery flows to a key load wiring bus WB1 through a general load wiring bus WB2 and a diode D3. The positive and negative poles of the general load mounted on the general load wiring busbar WB2 are connected to the storage battery, and the general load operates. The anode and the cathode of the critical load mounted on the critical load wiring busbar WB1 are connected with the storage battery, and the critical load works. Generally, after the load end of the setting relay KM2 is closed, the load end of the time-delay disconnection type time relay KT1 is disconnected. However, after the load end of the time-delay disconnection type time relay KT1 is disconnected, the coil of the relay KM1 is in a power-off state, and the load end of the relay KM1 is in a disconnected state. The battery positive current then flows to critical load wiring busbar WB 1. The anode and the cathode of the critical load mounted on the critical load wiring busbar WB1 are connected with the storage battery, and the critical load works. Due to the arrangement of the diode D3, the current on the critical load wiring busbar WB1 cannot flow to the general load wiring busbar WB2 through the diode D3, that is, the general load is disconnected from the positive electrode of the battery, and the general load stops working.
