Description

[0002] In order to comprehensively improve the service level of "getting electricity", continuously optimize the business environment for electricity consumption, better meet the people's pursuit of a better life, adhere to the "power supply reliability as the general grasp", and in order to reduce the comprehensive power outage time of users, the demand for the connection of generators to the low-voltage side of the public transformer is getting higher and higher. At present, in order to improve the power supply efficiency, when my country implements low-voltage line operations, generators are often used to replace maintenance lines to supply power to the affected loads. When implementing operations, the access of generators is a more rigorous work procedure. Under normal circumstances, the generator car will be switched to the load line only after the busbar is shut down. This process is usually manually operated, so there will be a short power outage on the load side. Only when all departments are perfectly connected and coordinated, the power outage time can be as fast as 3 seconds. Under normal circumstances, the power outage time is generally at the minute level, which makes the user side feel more obvious about the power outage, affecting the power supply quality. To address this problem, we plan to develop an automatic non-stop power access device for power generation vehicles, which can reduce the power outage time caused by the power generation vehicle access to less than 3 seconds, and simplify the access process. In this way, we can reduce the complexity of personnel operations while reducing the load end's perception of power outage time, achieving non-stop power access similar to that of a reclosing switch in time.

[0033] Example 2

[0034] Reference Figures 2 to 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a limiting groove 101a is provided on the top of the housing 101, the limiting groove 101a is in a rectangular shape, and a reset groove 101b is provided at the bottom thereof, the reset groove 101b is obliquely provided, and a reset spring 101c is arranged therein, and a switch sliding groove 101d is provided on the side wall of the limiting groove 101a.

[0035] A conversion slot 101e is provided below the limit slot 101a, and the conversion slot 101e is in the shape of a quarter arc. The busbar interface 102 is connected to the busbar of the switch cabinet, the busbar power supply interface 103 is connected to the busbar transformer, and the external power supply interface 104 is connected to the power output port of the power generation vehicle.

[0036] The switching rod 202 is of a right angle shape as a whole, and its size is adapted to the conversion slot 101e, and it is rotatably connected to the first conductive block 201a. One side of the switching rod 202 can be embedded in the limiting slot 101a, and the other side can rotate in the conversion slot 101e. The side of the switching rod 202 located in the limiting slot 101a is made of insulating material, and a sliding groove 202a is opened on the top. The side of the switching rod 202 located in the conversion slot 101e is made of conductive material and forms a passage with the first conductive block 201a, and its end is also connected to the first conductive sheet 202b, which is arc-shaped and can slide along the inner wall in the conversion slot 101e.

[0037] The switch slot 101d, the slot 202a and the slide switch 203 have the same vertical cross-section, and are all groove structures that are wide at the bottom and narrow at the top. When the switch rod 202 is inserted into the limit slot 101a, the switch slot 101d and the slot 202a can be aligned. The slide switch 203 can slide in the switch slot 101d and the slot 202a. The length of the slot 202a is twice that of the switch slot 101d, and the length of the slide switch 203 is the same as that of the slot 202a. The second conductive block 201b passes through the housing 101 and is connected to the conversion slot 101e, and its contact is set at the top of the arc outer wall of the conversion slot 101e.

[0038] The third conductive block 201c is disposed at the bottom of the conversion slot 101e. A compression chamber S is also disposed in the conversion slot 101e. A compression spring S1 is disposed in the compression chamber S. The third conductive block 201c is disposed at the bottom of the compression spring S1, and the fourth conductive block S2 is connected to the top. A trigger slot T is also provided on the inner wall of the conversion slot 101e. A trigger spring T1 and a trigger plate T2 connected to the trigger spring T1 are disposed in the trigger slot T. The length of the trigger spring T1 exceeds the depth of the trigger slot T in the initial state. The fourth conductive block S2 is disposed below the trigger slot T. The compression spring S1 is initially in a squeezed state.

[0039] Compared with the first embodiment, further, a limiting groove 101a is provided on the housing 101, and one side of the switch rod 202 can be matched and embedded in the limiting groove 101a, and a reset groove 101b is provided at the bottom of the limiting groove 101a, and the reset groove 101b is provided obliquely, and a reset spring 101c is provided therein, and the switch rod 202 is lifted by the reset spring 101c in the natural state. A conversion groove 101e is provided under the limiting groove 101a, and the conversion groove 101e is in a quarter arc shape, and the switch rod 202 is rotatably connected to the first conductive block 201a, and the first conductive sheet 202b and the connected side of the switch rod 202 can conduct electricity, so that a passage can be formed when it is connected to the conductive member 201.

[0040] When the springs are in a natural state and the sliding switch 203 is turned on, the return spring 101c lifts the top of the switching rod 202 upward, and the first conductive sheet 202b on the other side rotates clockwise until it contacts the contact of the second conductive block 201b extending into the conversion slot 101e, and the trigger spring T1 in the trigger slot T is in a squeezed state. The sliding switch 203 is turned on, and the trigger spring T1 pops out of the trigger plate T2, pushing the switching rod 202, and working together with the return spring 101c to prevent it from being in a vertical state. The compression spring S1 in the compression chamber S at the bottom of the trigger slot T is supported by the trigger slot T, so that it is always in a compressed state. When the switching rod 202 rotates, it moves away from the fourth conductive block S2 and connects to the contact of the second conductive block 201b, so that the switching rod 202 is connected to the second conductive block 201b, and the bus interface 102 is connected to the bus power supply interface 103 to realize the power supply of the bus transformer.

[0041] When the switch rod 202 is manually pressed down, the sliding switch 203 is moved, and the length of the sliding groove 202a is twice that of the switch sliding groove 101d. The sliding switch 203 is the same length as the sliding groove 202a. Half of the sliding switch 203 is in the switch sliding groove 101d, and the other half is in the sliding groove 202a. Since the switch sliding groove 101d, the sliding groove 202a and the sliding switch 203 have the same vertical cross-section, which is a groove structure with a wide bottom and a narrow top, the switch rod 202 can be embedded in the limit groove 101a. The switch rod 202 is fixed inside, the top of the switch rod 202 is in a horizontal state, and the bottom is in a vertical state. At this time, the switch rod 202 presses the trigger plate T2 into the trigger slot T, and the fourth conductive block S2 at the bottom of the trigger slot T is pressed down by the switch rod 202, and the compression spring S1 is squeezed and contracted, and the fourth conductive block S2 is pressed down and contacts the third conductive block 201c. The switch rod 202 is connected to the third conductive block 201c through the fourth conductive block S2, and the busbar interface 102 is connected to the external power supply interface 104, which is converted by the busbar power supply interface 103 to connect with the external power supply interface 104, so as to realize the rapid access of the power supply line of the power generator.
