The first switch 1, the third switch 3 and the interconnection switch 10 can be arranged in equipment such as a power distribution cabinet or a high-voltage cabinet. It can be understood that the utility power end a can normally supply power to the user end, and when the utility power end a fails or cannot supply electric energy, the emergency power end B can supply power to maintain the normal power supply of the user end. The emergency power supply end B can be a power supply vehicle.

The utility model discloses an overall scheme is for all being provided with the tool to lock subassembly that is used for controlling this switch combined floodgate or separating brake on first switch 1 and third switch 3, wherein, only has one set of key on these two switches for one of them switch of combined floodgate for only a department combined floodgate in first switch or the third switch, another department is the separating brake.

The first embodiment is as follows:

referring to fig. 1, fig. 2, fig. 3 and fig. 4, in the present embodiment, a double-lock assembly 5 is disposed on each of the first switch 1 and the third switch 3, wherein the double-lock assembly 5 is used for controlling switching on or off of the first switch 1 and the third switch 3, and the double-lock assembly is disposed on the switches, so as to control the number of keys of the double-lock assembly 5 to achieve switching between different power supply terminals, thereby ensuring that the two power supply terminals do not run in parallel.

Specifically, the double lock assembly 5 includes an a lock 7, a B lock 8, a first rotating member 51 and a second rotating member 52, the first rotating member 51 is disposed on the a lock 7 and rotates due to the rotation of the a lock 7, and the second rotating member 52 is disposed on the B lock 8 and rotates due to the rotation of the B lock 8. The a lock 7 and the B lock 8 are both locks that are often used in the market, and when the a lock 7 and the B lock 8 rotate, they both rotate 90 degrees, and then both the first rotating member 51 and the second rotating member 52 also rotate 90 degrees. As can be seen from fig. 3 and 4, the first rotating member 51 has a fan shape as a whole, the second rotating member 52 has a circular or semicircular shape as a whole, and one side of the first rotating member 51 is recessed inward to form a circular arc avoiding groove 53 for avoiding the second rotating member 52. It can be understood that fig. 3 is a switching-off state of the double-lock assembly, fig. 4 is a switching-on state of the double-lock assembly, and when fig. 3 is changed into fig. 4, the first rotating member 51 needs to be rotated clockwise by 90 degrees, and due to the arrangement of the arc avoiding groove 53, the second rotating member 52 can be rotated to be embedded into the arc avoiding groove 53, at this time, due to the blocking of the first rotating member 51, the first rotating member 51 cannot be rotated any more, at this time, the key of the a lock 7 and the key of the B lock 8 cannot be pulled out, and the switch is in the switching-on state. When the state is changed from fig. 4 to fig. 3, the second rotating member 52 needs to be rotated 90 degrees counterclockwise, and the first rotating member 51 can be rotated 90 degrees counterclockwise, at this time, both the key of the a lock and the key of the B lock can be taken out, and the switch is in the open state. Therefore, when the first switch 1 or the third switch 3 is switched off, the key can be pulled out from the A lock 7 and the B lock 8, and the key cannot be pulled out when the switch is switched on, so that the first switch 1 or the third switch 3 can be opened only when the key of the A lock and the key of the B lock are inserted, and only one switch is switched on.

Therefore, when the keys of the A lock 7 and the B lock 8 are both one, only one of the first switch 1 or the third switch 3 is switched on, and the other switch is switched off, so that the emergency power supply end and the commercial power end cannot run in parallel at the same time.

Meanwhile, the double-lock assembly 5 further comprises a fixing plate 57, and the a lock 7 and the B lock 8 on the double-lock assembly 5 are both installed on the fixing plate 57. The first switch 1 and the third switch 3 are both provided with a brake separating button 55, and the double-lock assembly 5 is provided with mounting holes which can be mounted on the first switch and the third switch through screws. Before the opening button 55 is not pressed, the switch is in a closing state, and during the pressing process, the switch performs opening operation, so that the opening button 55 can drive the rocker 56 to move backwards when pressed, at the moment, the lock A7 of the double-lock assembly 5 can be rotated, the blocking wall 54 of the first rotating member 51 is driven to block the rocker 56, and the opening button 55 is prevented from rebounding, so that the switch can only be in an opening state.

Example two:

referring to fig. 5, fig. 6, fig. 7, fig. 8 and fig. 9, in the present embodiment, the first switch 1 and the third switch 3 are provided with the single lock assembly 6, where the single lock assembly 6 is used to control switching on or off of the first switch 1 and the third switch 3, and the single lock assembly 6 is provided on the switch to control the number of keys of the single lock assembly 6, so as to achieve switching between different power supply terminals, and ensure that the two power supply terminals do not run in parallel.

Specifically, the single lock assembly 6 includes a frame 61, a lock 66 disposed in the frame 61, a vertical gear assembly 62 connected to the lock 66, and a connecting rod 63 connected to the vertical gear assembly 62. The vertical gear assembly 62 is a conventional gear combination that changes the direction of rotation. One end of the connecting rod 63 extends out of the frame body 61, and a stopper 64 is provided on the end. In addition, the first switch 1 and the third switch 3 may be both molded case switch operating mechanisms, an empty slot 65 matched with the stopper 64 is formed on the molded case switch operating mechanism, and the empty slot 65 is formed when the first switch 1 or the third switch 3 is opened.

In this embodiment, the first switch 1 and the third switch 3 only have one key of the lock 66, wherein the lock 66 may be an a-lock or a B-lock. It can be understood that at most one of the first switch 1 or the third switch 3 is in a closed state, so that a power supply system is protected, switching between an emergency power supply end and a commercial power end is realized, and parallel operation cannot be performed simultaneously.

In addition, the frame body 1 also comprises a positioning assembly 2, and the positioning assembly 2 comprises a sinking hole 21 arranged at the lower end part of the vertical gear assembly 33, a spring 22 arranged at the bottom of the sinking hole 21 and a rolling ball 23 linked with the spring 22; a spherical bulge 24 is arranged on the bottom plate of the frame body 61, the rolling ball 23 penetrates through the opening of the sinking hole 21 and reaches the other side of the spherical bulge 23 through the spring 22, and the hand feeling can be improved before the lock 66 is screwed to the limit position.

Example three:

referring to fig. 10, and with reference to the contents of the first embodiment and the second embodiment, in the present embodiment, a double-lock component 5 is disposed on the first switch 1, and the double-lock component 5 is used for controlling the switching on or off of the first switch 1. The third switch 3 is provided with a single lock assembly 6, and the single lock assembly 6 is used for controlling switching on or switching off of the third switch 3. In this embodiment, the lock 66 on the single lock assembly would be an A-lock. The number of keys of the single lock assembly and the double lock assembly is controlled, switching between different power supply ends is achieved, and parallel operation of the two power supply ends is guaranteed not to occur.

Specifically, the first switch 1 and the third switch 3 have only one key for the a-lock 7 and one key for the B-lock 8. It can be understood that when the first switch 1 is in the opening state, the a lock key on the double-lock component 5 can be taken out, and the third switch 3 can be switched on, but after the a lock key on the double-lock component is reduced, the first switch 1 cannot be switched on, and only can be in the opening state; similarly, when the first switch is switched on, the lock key A and the lock key B are both arranged on the first switch 1, the lock key A and the lock key B cannot be taken out, the third switch 3 cannot be switched on and can only be in a switching-off state, switching between an emergency power supply end and a commercial power supply end is realized, and simultaneous parallel operation cannot be realized, so that a power supply system is protected.

To sum up, can find out, the unable power supply that breaks down at the commercial power end, when needing to supply power through emergent power supply end, can adopt following several kinds of schemes to guarantee the switching between commercial power end and the emergent power supply end, simultaneously, guarantees system power supply safety: (1) the first switch and the third switch are both provided with double lock components, and the A lock key and the B lock key on the two switches are only one; (2) the first switch and the third switch are both provided with single lock components, and only one lock key is arranged on the first switch and the third switch; (3) the first switch is provided with a double-lock assembly, the third switch is provided with a single-lock assembly, and the two switches only have one A lock key and one B lock key.
