Referring to fig. 10, the side frame 11 is formed by bending a plate through a sheet metal process, two ends of the bent plate are welded linearly to form a sealing tube, two ports of the side frame are further provided with connecting flanges, and the bottom support and the top cover are respectively connected with the connecting flanges at the matching positions through threaded connectors. Generally, when the joint of the members is a linear seam, continuous welding along the linear seam is called linear welding.
In this embodiment, the circuitry in the control box for the WIG craft may use the circuitry shown in FIGS. 1-3.
Referring to fig. 1-3, the position of the time delay relay KT1, starting battery contact MZJ2 in the complete circuit is seen in fig. 13. Wherein contact F in fig. 2 connects to critical load wiring strap WB2 in fig. 13. The specific logic is as follows.
A power distribution circuit comprises a storage battery, a key load wiring busbar WB1, a general load wiring busbar BUS B, a diode D5, a diode D8, a change-over switch S1, a relay KM2, a time-delay disconnection type time relay KT1 and a relay MZJ 2.
The positive electrode of the storage battery, the load end of the relay MZJ2, the general load wiring BUS BUS B, the diode D5 and the key load wiring BUS 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 connection BUS BUS B and the negative electrode of the storage battery form a general load connection terminal group. And the key load wiring BUS bar BUS B and the negative electrode of the storage battery form a key 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 in series with the coil of the relay MZJ2, and the load end of the relay MZJ2 forms a switch B. In the embodiment, the relay MZJ2 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 MZJ2, so that one relay MZJ2 may be omitted.
The power distribution circuit of the present invention is preferably installed in an aircraft, including a ground effect craft, or a submarine. 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 MZJ2 is electrified, the load end of the relay MZJ2 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 BUS B and the diode D5. The anode and the cathode of a common load mounted on the common load wiring BUS bar BUS B are connected with the storage battery, and the common load works. 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 D8 prevents current on the critical load wiring busbar WB1 from passing through diode D8 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 MZJ2 is still in a power-on state, the load end of the relay MZJ2 is still in a closed state, and the positive electrode current of the storage battery flows to the key load wiring BUS bar WB1 through the general load wiring BUS bar BUS B and the diode D5. The anode and the cathode of a common load mounted on the common load wiring BUS bar BUS B are connected with the storage battery, and the common load works. 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 MZJ2 is in a power-off state, and the load end of the relay MZJ2 is in an off 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 D5, the current on the critical load busbar WB1 cannot flow to the general load busbar BUS B through the diode D5, i.e., the general load is disconnected from the battery positive pole, and the general load stops working.
The invention is described in detail above with reference to the figures and examples. It should be understood that in practice the description of all possible embodiments is not exhaustive and that the inventive concepts are described herein as far as possible by way of illustration. Without departing from the inventive concept of the present invention and without any creative work, a person skilled in the art should, in all of the embodiments, make optional combinations of technical features and experimental changes of specific parameters, or make a routine replacement of the disclosed technical means by using the prior art in the technical field to form specific embodiments, which belong to the content implicitly disclosed by the present invention.
