Background technique

With the continuous development of power transmission technology, as well as the actual needs of various installations and maintenance, the power transmission method has changed from the simplest method that does not need to use the module base of the incoming and outgoing lines, but directly realizes the power transmission by the switch. It has gradually developed into the method of using the module base of the incoming and outgoing lines. Usually, this transmission method using the modular base of the incoming and outgoing lines is widely used in power systems, especially in substation AC systems, AC-DC integrated power systems, control cabinets, power distribution cabinets, and distribution cabinets. In the field of power distribution such as electric boxes, it mainly takes power from the main busbar or vertical busbar, first passes through the base of the incoming and outgoing line module, then passes through the switch (the switch is not part of the base), and then Back to the base to transmit to the corresponding load, the schematic diagram of the specific power transmission direction is shown in Figure 1.

2. Similar to the switch base technology of the Wiener bus system, this technology neither completely separates the switch nor realizes the online maintenance of the switch, but it can realize the preset installation of the switch, and this base only solves the problem of The power transmission at the incoming line end of the switch does not solve the problem of electric power transmission at the outgoing line end.

As shown in Figure 14 and Figure 15 again, in this embodiment, in order to make the first protective plate 141 and the second protective plate 142 can automatically block each incoming line plug-in end 15 and each outgoing line plug-in end 16 respectively, wherein , the guide member of each channel is built with an elastic member 145, and one end of the first protective plate 141 and the second protective plate 142 near the elastic member 145 is provided with a guide portion 1432 (such as a guide rod), so that each elastic One end of the piece 145 can be abutted against the corresponding channel, and the other end is passed through the corresponding guide portion 1432 .

As shown in Figures 14 and 15, in this embodiment, in order to prevent over-positioning, the end of the first protective plate 141 close to the elastic member 145 is protruded with a top 1433, so that the first push rod 143 can only move forward. Displaced to a certain distance, when the first protective plate 141 just blocks each incoming line insertion end 15, the first push rod 143 can just be against the first protective plate 141, and in the same way, the second protective plate 142 is close to the elastic member One end of 145 also protrudes from a top 1433 . In this embodiment, the first protective plate 141 is the same as the second protective plate 142, and the first push rod 143 is the same as the second push rod 144. In fact, the corresponding parts may be different, depending on actual needs. .

From the above, it can be understood that in this embodiment, when the switch assembly is detached from the base, the corresponding elastic member 145 can push the first push rod 143 forward under the action of its resilience, and synchronously drive the first push rod 143 to move forward. The protective plate 141 moves to the right until it covers the plug-in terminals 15 of the incoming wires, so as to prevent the operator from accidentally touching the electric shock. Correspondingly, the corresponding elastic member 145 can push the second push rod 144 under the action of its resilience Move forward, and synchronously drive the second protective plate 142 to move to the left, until it covers each outgoing line insertion end 16 . It can also be understood that when the base needs to be connected to a switch assembly, the first push rod 143 and the second push rod 144 can be pushed back manually, so that each incoming line insertion end 15 and each outgoing line plug can be opened correspondingly. Terminal 16. It should be noted that, in this embodiment, the first protective plate 141 and the second protective plate 142 are arranged on the inside of each cover plate 131, so that the personal safety of the operator can be fully ensured.

Further, in order to detect the temperature rise of each incoming line plug-in terminal 15 and each outgoing line plug-in terminal 16 in a timely manner, and then judge whether each plug-in joint is in good contact, in a preferred embodiment provided by the present invention, each A temperature sensor (not shown) is provided on the connecting lines of the line plug-in terminal 15 and each outgoing-line plug-in terminal 16. In addition, in the base, a PCB board 3 for temperature sampling is also provided, so that the detected The temperature of each socket is concentrated on the PCB board 3 through each temperature sensor, and then uploaded to the monitoring module for information processing through corresponding devices to display the temperature rise of each connection, so as to know whether its working performance is normal , so as to ensure the safety performance of the base.

It should be noted that although this article focuses on the transfer of three-phase current with a three-level base, in fact, the base can be applied to the transfer of any current level, that is, it is not limited to the three-phase current It can also be assembled into a single-stage or multi-stage base, that is, it is not limited to a three-stage base.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Various modifications and variations of the present invention will occur to those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of the claims of the present invention.
