Referring to fig. 1 to 3, the present embodiment provides a time switch, which includes a control circuit and a first isolation switch K1; the control circuit comprises a power supply E; the first input end of the first isolating switch K1 is connected with the positive electrode of the power supply E, the second input end of the first isolating switch K1 is connected with the negative electrode of the power supply E, the first output end of the first isolating switch K1 is connected with the positive electrode of the load end, and the second output end of the first isolating switch K1 is connected with the negative electrode of the load end; the pre-charging branch of the energy storage high-voltage box is connected with the first isolating switch K1 in parallel, and comprises a pre-charging resistor R1 and a pre-charging switch K2 which are connected in series; the first isolating switch K1 comprises a first motor 11 and a first operating mechanism 12 connected with the first motor 11, and the first motor 11 is used for driving the first operating mechanism 12 to act so as to enable the first isolating switch K1 to be opened or closed. The time sequence switch and the energy storage high-voltage box are simple in circuit, are convenient for a user to wire, and can effectively improve the problem of contact adhesion.
It should be noted that, first, the time sequence switch includes a control circuit and a first isolation switch K1, where the control circuit includes a power source E; the pre-charging branch of the energy storage high-voltage box is connected in parallel with the first isolating switch K1, and the pre-charging branch further comprises a pre-charging resistor R1 and a pre-charging switch K2 which are connected in series, as shown in figure 1.
In this embodiment, the precharge branch may be a part of the time switch, that is, may be built into the time switch, as shown in fig. 2 to 6; alternatively, the pre-charge branch may be independent of the time switch, i.e. external to the time switch, as shown in fig. 7. When the precharge branch is opened Guan Waizhi with respect to the timing, as shown in fig. 7, the first disconnecting switch K1 of the timing switch needs to be electrically connected in parallel with the external precharge branch when the timing switch is in use, as shown in fig. 1.
The first isolating switch K1 includes a first input end, a second input end, a first output end and a second output end, where the first input end is connected with the positive electrode of the power source E, the second input end is connected with the negative electrode of the power source E, the first output end is connected with the positive electrode of the load end, and the second output end is connected with the negative electrode of the load end, as shown in fig. 1.
Secondly, the pre-charging branch is connected in parallel with the first isolating switch, so that when the time sequence switch works, the high-voltage load energy storage capacitor at the load end can be pre-charged, and after the pre-charging is completed, the first isolating switch K1 is switched on, so that the pre-charging branch is short-circuited (namely, the pre-charging switch K2 and the pre-charging resistor R1 are short-circuited), and the load end can be started normally. After the measures are taken, the impact current at the moment of starting the circuit can be greatly reduced. The type of the precharge switch K2 is not limited in the present utility model.
Third, the first disconnecting switch K1 includes a first motor 11 and a first operating mechanism 12 connected to the first motor 11, where the first motor 11 is used to drive the first operating mechanism 12 to act, so that the first operating mechanism 12 is opened or closed.
The first disconnecting switch K1 is closed when the first operating mechanism 12 is closed, and the first disconnecting switch K1 is opened when the first operating mechanism 12 is opened.
In summary, the time sequence switch provided by the utility model comprises a control circuit and a first isolating switch, wherein the control circuit comprises a power supply E; the first input end of the first isolating switch K1 is connected with the positive electrode of the power supply E, the second input end of the first isolating switch K1 is connected with the negative electrode of the power supply E, the first output end of the first isolating switch K1 is connected with the positive electrode of the load end, and the second output end of the first isolating switch K1 is connected with the negative electrode of the load end; the pre-charging branch of the energy storage high-voltage box is connected with the first isolating switch K1 in parallel, and comprises a pre-charging resistor R1 and a pre-charging switch K2 which are connected in series; the first isolating switch K1 comprises a first motor 11 and a first operating mechanism 12 connected with the first motor 11, and the first motor 11 is used for driving the first operating mechanism 12 to act so as to enable the first isolating switch K1 to be opened or closed. The time sequence switch comprises a control circuit and a first isolating switch K1; the pre-charging branch (comprising the pre-charging resistor R1 and the pre-charging switch K2 which are connected in series) is connected to the first isolating switch K1 in parallel, so that compared with the prior art, the time sequence switch provided by the utility model has the advantages that on one hand, the circuit structure is simpler, the number of customer wiring is less, the installation time is short, the cost can be effectively reduced, and the user experience is improved; on the other hand, the switch adopted on the main circuit (namely the circuit where the first isolating switch K1 is positioned) of the control circuit of the time sequence switch is the first isolating switch, and the pre-charging branch which is connected with the first isolating switch K1 in parallel and comprises the pre-charging resistor R1 and the pre-charging switch K2 is arranged, so that the impact current of the circuit at the starting moment can be effectively reduced, and compared with the case that one main positive contactor and one main negative contactor are adopted in the main circuit in the prior art, the problem of contact adhesion of the main positive contactor and the main negative contactor in the prior art can be effectively solved by adopting the first isolating switch K1.
With continued reference to fig. 1, optionally, the control circuit provided by the present utility model further includes a first fuse FU1, wherein one end of the first fuse FU1 is connected to the positive electrode of the power source E, and the other end of the first fuse FU1 is connected to the first input end of the first isolating switch K1.
It should be understood that the first fuse FU1 is a disposable element for connecting to a control circuit for protecting a time switch in the control circuit, and when the current in the control circuit is too high, the metal wire or metal sheet in the first fuse FU1 is melted by generating high temperature, which can cause the control circuit to open and interrupt the current, thereby functioning as a protection circuit. Of course, a new fuse needs to be manually replaced after the old fuse of the first fuse FU1 blows to restore the circuit to operation.
To further protect the circuit, the control circuit may further include a second fuse FU2, one end of the second fuse FU2 is connected to the negative electrode of the power source E, and the other end is connected to the second input terminal of the first isolating switch K1. The operation principle and function of the second fuse FU2 are the same as those of the first fuse FU1, and the description thereof will not be repeated here.
In order to facilitate the control of the opening or closing (i.e. opening or closing) of the first disconnecting switch K1 and the pre-charging switch K2, optionally, the time sequence switch further comprises a controller 50, and the controller 50 is electrically connected with the first disconnecting switch K1 and the pre-charging switch K2, respectively, for controlling the opening and closing of the first disconnecting switch K1 and the opening and closing of the pre-charging switch K2.
The controller 50 is electrically connected to the first isolating switch K1, and specifically, the controller 50 may control the first motor 11 of the first isolating switch K1 to implement opening or closing of the first operating mechanism 12. For example, the controller 50 may cause the first operating mechanism 12 to be opened or closed by controlling the power on and off of the first motor 11, or cause the first operating mechanism 12 to be opened or closed by controlling the forward rotation or reverse rotation of the first motor 11.
In addition, the first isolating switch K1 may be opened or closed by manual operation, for example, the first isolating switch K1 may be opened or closed by driving an operation handle of the first isolating switch.
In this embodiment, the precharge switch K2 may be an isolating switch or a relay.
For example, in a first possible embodiment, as shown in fig. 2 and 3, optionally, the precharge switch K2 is a relay, the coil 21 of the relay is electrically connected to the controller 50, and the controller 50 is configured to control the coil 21 to be powered on or powered off; when the coil 21 is powered on, one end of a contact of the relay is connected with the pre-charge resistor R1, and the other end of the contact is connected with the output end of the first isolating switch K1.
When the precharge switch K2 is a relay, the coil 21 of the relay is electrically connected to the controller 50. In this way, the controller 50 can cause the contacts of the relay to move by controlling the coils 21 to be powered on or off, thereby causing the contacts to be on or off with the pre-charge branch.
Illustratively, when the controller 50 controls the coil 21 to be energized, one end of the contact of the relay is connected to the precharge resistor R1, and the other end is connected to the first isolated output terminal; when the controller 50 controls the coil 21 to be deenergized, one end of the contact of the relay is disconnected from the precharge resistor R1, and/or the other end of the contact of the relay is disconnected from the first isolated output terminal.
In a second possible embodiment, optionally, as shown in fig. 4 to 6, the precharge switch K2 is a second isolating switch, and the controller 50 is electrically connected to the second isolating switch, for controlling the opening and closing of the second isolating switch.
That is, in this embodiment, the precharge switch K2 is also an isolating switch. It should be noted that the above-mentioned pre-charging switch K2 is a relay or a second isolating switch, which is only two examples, and is not a limitation of the pre-charging switch K2 of the present utility model, and one skilled in the art may select any one of the above-mentioned modes according to practical situations, or other switch types may also be used for the pre-charging switch K2.
In the first embodiment, when the precharge switch K2 is the second isolation switch, the first isolation switch K1 and the second isolation switch may be independently driven by the first motor 11 and the second motor 22, respectively. For example, as shown in fig. 4 and 5, the second isolating switch includes a second motor 22 and a second operating mechanism 23 connected to the second motor 22, and the second motor 22 drives the second operating mechanism 23 to move so as to open or close the second isolating switch.
That is, the first motor 11 drives the first operating mechanism 12 to move to open or close the first operating mechanism 12, thereby opening or closing the first isolating switch K1; the second motor 22 drives the second operating mechanism 23 to move so as to open or close the second operating mechanism 23, thereby opening or closing the second isolating switch. The first isolating switch K1 and the second isolating switch are respectively and independently controlled through the corresponding motors.
At this time, as shown in fig. 5, alternatively, the rotation axis of the output shaft of the first motor 11 is collinear with the rotation axis of the moving contact of the first disconnecting switch K1; and/or the axis of rotation of the output shaft of the second motor 22 is collinear with the axis of rotation of the moving contact of the second disconnector. Thus, the whole structures of the first isolating switch K1 and the second isolating switch are clear, and the assembly operation of a user is facilitated.
Second, when the precharge switch K2 is a second isolating switch, the first isolating switch K1 and the second isolating switch may be driven by sharing the first motor 11, for example, as shown in fig. 6, optionally, the second isolating switch includes a second operating mechanism 23, and the first motor 11 is further used to drive the second operating mechanism 23 to move, so that the second isolating switch is opened or closed.
That is, when the precharge switch K2 is a second isolation switch, the second isolation switch may be operated by driving the second operating mechanism 23 of the second isolation switch by the first motor 11 using the first isolation switch K1, so that the second operating mechanism 23 is opened or closed. That is, the first disconnecting switch K1 and the second disconnecting switch share one motor for driving both the first disconnecting switch K1 to be closed or opened and the second disconnecting switch to be closed or opened.
When the first motor 11 is used to drive both the first disconnector K1 and the second disconnector K1 to be closed or opened, this can be achieved by: alternatively, as shown in fig. 6, the first operating mechanism 12 includes a first gear 121, the second operating mechanism 23 includes a second gear 231, and a third gear is sleeved and fixed at the output end of the first motor 11 and meshed with the first gear 121 and the second gear 231, respectively; the first motor 11 can drive the first gear 121 and the second gear 231 to rotate through the third gear respectively, so that the first disconnecting switch K1 and the second disconnecting switch are switched on and off.
Therefore, compared with the mode that the first isolating switch K1 and the second isolating switch are driven by corresponding motors respectively, the mode can save one motor, and the number of parts and the cost are reduced.
In addition, the utility model does not limit the rotation angle of the first gear 121 and the rotation angle of the second gear 231, the first motor 11 can drive the second gear 231 to rotate a first angle to switch on the second isolating switch, and drive the second gear 231 to reversely rotate a first angle to switch off the second isolating switch; the first isolating switch K1 is switched on by driving the first gear 121 to rotate by a second angle, and the first isolating switch K1 is switched on by driving the first gear 121 to reversely rotate by the second angle.
The first angle and the second angle are different, for example, the second angle may be twice the first angle. Of course, the above-mentioned proportional relation between the first angle and the second angle is merely an example, and should not be taken as limiting the present utility model, and a person skilled in the art may determine the specific angle values of the first angle and the second angle according to the actual situation.
In another aspect of the present utility model, an energy storage high voltage tank is provided, which includes the time switch described above. Because the specific structure and the beneficial effects of the time switch are described and illustrated in detail in the foregoing, the present utility model is not repeated here.
The above description is only of alternative embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
In addition, the specific features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described further.
