Specifically, one end of the PT terminal 130 may be connected to any position between the circuit breaker 110 and the disconnection switch 120. The other end of the PT terminal 130 opposite to the one end (i.e., the end protruding outside the device) reserves an interface for electrical connection with an external structure. Specifically, the reserved interface may be a two-hole socket or a three-hole socket.
The PT cable terminal includes: the circuit breaker 110, the disconnector 120, and a PT terminal 130, one end of the PT terminal 130 is connected between the circuit breaker 110 and the disconnector 120, and the other end of the PT terminal 130 opposite to the one end reserves an interface for electrical connection with an external structure. In the using process, before the external circuit is switched on, the isolating switch 120 can be closed, after the isolating switch 120 is closed, the connection between the PT terminal 130 and the external circuit is kept in the open circuit state, and at the moment, the external circuit is switched on, so that the problem of reverse power transmission can be effectively avoided.
In some embodiments of the present application, the plurality of disconnectors 120 may be provided in parallel, and one end of each disconnector 120 is connected to one end of the PT cable terminal (i.e., an end located in the device). Specifically, the number of the isolation switches 120 may be three, each of the isolation switches 120 corresponds to one of the phases in the three-phase circuit, and the three isolation switches 120 may be used to control connection or disconnection of the three-phase circuit.
In some embodiments of the present application, each of the isolation switches 120 includes: a first end 122, a second end 121, and a control structure 123.
The control structure 123 is rotatably connected to the first end 122, and the control structure 123 may be continuously electrically connected to the first end 122. The control structure 123 has a first state and a second state, in the first state, the control structure 123 rotates to a preset angle, and in the preset angle, the control structure 123 contacts and is electrically connected to the second end 121, and at this time, the disconnecting switch 120 is in a connected state; in the second state, the control structure 123 rotates to other angles, and in other angles, the control structure 123 is separated from the second end 121, so that the control structure 123 cannot be electrically connected to the second end 121, and the isolation switch 120 is in the off state.
Specifically, the first end 122 and the second end 121 may be spaced apart in the vertical direction. In the first state, the angle between the control structure 123 and the horizontal plane may be 90 °, that is, the control structure 123 is in the vertical state, and the control structure 123 may be connected to the first end 122 and the second end 121 at the same time, in the second state, the angle between the control structure 123 and the horizontal plane may be 60 °, that is, the control structure 123 is separated from the second end 121 by being offset by 30 ° from the vertical direction, and the control structure 123 is electrically connected to only the first end 122, and the first end 122 and the second end 121 are kept in the open circuit state. In this case, the predetermined angle is 30 °. Of course, the preset angle may be other angles, for example, the preset angle may be other angles such as 40 ° and 45 °.
The second end 121 is connected to the circuit breaker 110. Specifically, the second end 121 may be electrically connected to the circuit breaker 110 through a wire. One end (i.e., the end located in the device) of the PT terminal 130 is connected to the second terminal 121 of the disconnection switch 120. Specifically, the PT terminal 130 may be electrically connected to the second end 121 by welding, winding, or the like.
In some embodiments of the present application, the cable terminal mounting structure may further include: a connecting structure 140.
One end of the connection structure 140 is connected to one of the disconnectors 120 and the second end 121. Specifically, one end of the connection structure 140 may also be connected to the second ends 121 of all the disconnectors 120, and since all the disconnectors 120 are connected in parallel, the connection structure 140 is connected to the second end 121 of one of the disconnectors 120, that is, the connection structure 140 is connected between the disconnectors 120 and the circuit breaker 110. The other end of the connection structure 140 has a through hole 141, and the PT terminal 130 is electrically connected to the connection structure 140 through the through hole 141. Specifically, the PT terminal 130 may be electrically connected to the connection structure 140 in a winding manner, and the connection between the PT terminal 130 and the connection structure 140 may be more stable using the through hole 141.
In some embodiments of the present application, the other end of the connecting structure 140 opposite to the one end protrudes from the second end 121, and the other end of the connecting structure 140 is bent toward a direction close to the first end 122. The second end 121 is connected to the PT terminal 130, and since the second end 121 is bent, a portion of the PT terminal 130 connected to the second end 121 is far away from the control structure 123, so as to prevent the control structure 123 from contacting the PT terminal 130 during rotation.
In some embodiments of the present application, the connecting structure 140 and the second end 121 are a unitary structure. In this case, the connection structure 140 and the second end 121 can be stably connected and can be easily manufactured. And because the connection structure 140 and the second end 121 are both located at fixed positions, they can bear the action of a large pulling force from the PT terminal 130, and effectively prevent the occurrence of the situation that the connection structure 140 and the second end 121 are separated from each other due to the external force applied to the PT terminal 130.
Specifically, the connecting structure 140 and the second end 121 may form a "U" shape together, one end of the "U" shape is the connecting structure 140, and the other end of the "U" shape is the second end 121. In this case, the connection structure 140 and the second end 121 have a certain interval therebetween, and the control structure 123 may maintain a certain gap between the control structure 123 and the connection structure 140 when contacting the second end 121; and under the condition that the control structure 123 is separated from the second end 121, a certain gap is still kept between the control structure 123 and the connecting structure 140, so that the control structure 123 and the control structure 140 can be effectively prevented from being contacted to influence the open circuit state between the first end 122 and the second end 121.
Specifically, the connecting structure 140, the first end 122 and the second end 121 may be made of copper material. Because the copper material has the characteristics of high conductivity, low price, wear resistance and the like, the connecting structure 140, the first end 122 and the second end 121 which are made of the copper material have the characteristics of high conductivity, low manufacturing cost and long service life.
In some embodiments of the present application, the control structure 123 may include: an actuating member and a driving member.

In particular, the actuating member may be made of a copper material. Because the copper material has the characteristics of high conductivity, low price, wear resistance and the like, the executive component made of the copper material has the characteristics of high conductivity, low manufacturing cost and long service life.

Specifically, the driving member may be an insulating structure, and the driving member may be configured to be rod-shaped and rotate through rotation of the rotation control actuating member. Specifically, the driving member may be a quadrangular prism, and the user may control the rotation of the actuating member by controlling the rotation of the driving member.
Of course, the driving member may not only be a quadrangular prism, but also include a driving motor, an output shaft of the driving motor is connected to a central axis of the quadrangular prism in a transmission manner, the driving motor can drive the quadrangular prism to rotate, and the quadrangular prism can drive the actuating member to move in the rotating process, so that the actuating member can be switched between the first state and the second state.
In some embodiments of the present application, all of the actuators in the control structure 123 are driven by the same driving member. The user can control all the actuating parts to rotate by controlling the same driving part, so that all the actuating parts can be synchronously in the first state, and all the actuating parts can be synchronously in the second state.
Specifically, all the control structures 123 may be fixedly connected to the driving member, that is, all the control structures 123 are fixedly connected to the quadrangular prism, and a certain interval is provided between adjacent control structures 123, so as to ensure that the adjacent control structures 123 can work independently; and different control structures 123 are distributed along the central axis of the quadrangular prism, so that the complete synchronization of the motion states of different control structures 123 is ensured, and the states of the control structures 123 at the same time are ensured to be the same.
