Further, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Example 1
Referring to fig. 1 to 6, the present embodiment provides a multifunctional anti-slipping high-voltage disconnecting link, which includes a disconnecting link unit 100 and an anti-slipping unit 200, wherein the disconnecting link unit 100 provides two communication modes, and the anti-slipping unit 200 prevents the disconnecting link from breaking when the connection of one side of the disconnecting link is selected.
Specifically, the disconnecting link unit 100 comprises a mounting plate 101, a bracket 102 mounted in the middle of the mounting plate 101, a swing rod 103 hinged to the bracket 102, and a grounding pile 104 and a conductive pile 105 respectively mounted at two ends of the mounting plate 101, wherein a metal sheet 106 is embedded in the swing rod 103, and one end of the bracket 102, which is far away from the mounting plate 101, is provided with a hinge hole 102a; the mounting plate 101 is an insulator, the swing rod 103 can rotate around the hinge hole 102a on the bracket 102, and then is selectively connected with the grounding pile 104 or the conductive pile 105, when the swing rod 103 rotates to the state that the metal sheet 106 is connected with the conductive pile 105, the circuit can be normally used as a passage, and when the metal sheet 106 is connected with the grounding pile 104, the current of the circuit is cut off, the circuit is grounded, and the operations such as maintenance and the like can be performed.
Further, the anti-dropping unit 200 comprises a first connecting column 201 located on the bracket 102, a second connecting column 202 located on the swing link 103, and a first spring 203; the first spring 203 is a tension spring, which mainly bears axial tension, one end of the first spring 203 is connected with the first connecting column 201, the other end of the first spring 203 is connected with the second connecting column 202, and the first connecting column 201 is located at one end of the bracket 102 close to the mounting plate 101. Therefore, when the swing rod 103 rotates to one position between the grounding pile 104 and the conductive pile 105, two connection points of the first spring 203 and the hinge hole 102a form a triangular stable structure, at the moment, the tension of the first spring 203 enables the swing rod 103 to be tightly connected with the grounding pile 104 or the conductive pile 105, when the state needs to be switched, the operation on the swing rod 103 overcomes the tension of the first spring 203, when the swing rod 103 rotates to be perpendicular to the mounting plate 101, the first connection column 201, the second connection column 202 and the hinge hole 102a are located at collinear positions, at the moment, the length of the first spring 203 is longest, and when the swing rod 103 is slightly shifted in a certain direction, the first connection column 201, the second connection column 202 and the hinge hole 102a form a triangle, and under the action of the tension of the first spring 203, the rotation of the swing rod 103 is directly driven to be connected with the grounding pile 104 or the conductive pile 105, so that a triangular stable structure is formed, and the high-voltage disconnecting switch in a working state is prevented, and safety accidents are caused.
Preferably, the present invention can also shield the function of the grounding peg 104 without the need for grounding, as follows:
a round hole 101a is formed in the mounting plate 101, one end of the grounding pile 104 is connected with a rotating column 104a, the rotating column 104a is connected with the round hole 101a, the other end of the grounding pile 104 is recessed inwards to form a first groove 104b and a second groove 104c which are perpendicular to each other, the depth of the first groove 104b is larger than that of the second groove 104c, a conductor block 104d is arranged in the first groove 104b, and the conductor block 104d is connected with a grounding wire 104e; the diameter of the round hole 101a is consistent with that of the rotating column 104a, so that the rotating column 104a can be embedded into the round hole 101a and rotate with the round hole 101a as the center of a circle, the end of the grounding pile 104, which is used for being connected with the metal sheet 106 in the swing rod 103, is provided with a first groove 104b, the width of the first groove 104b is consistent with the thickness of the metal sheet 106, the bottom of the first groove 104b is provided with a conductor block 104d, when grounding is selected, the swing rod 103 swings to the grounding pile 104, the metal sheet 106 is embedded into the bottom of the first groove 104b and is connected with the conductor block 104d, the conductor block 104d is connected with a grounding wire 104e, and when the metal sheet 106 is embedded into the first groove 104b, the device conducts grounding processing on a circuit.
When the grounding function is not needed in the circuit, the metal sheet 106 cannot be directly embedded into the first groove 104b to connect with the conductor block 104d, and then a second groove 104c perpendicular to the direction of the first groove 104b is provided, and the depth of the first groove 104b is greater than that of the second groove 104c, it should be noted that, even if the conductor block 104d is provided in the first groove 104b, the depth of the first groove 104b minus the depth of the conductor block 104d is greater than that of the second groove 104 c; thus, when the grounding is not needed, the metal sheet 106 is not turned to the first groove 104b but turned to the second groove 104c, and the depth of the second groove 104c is smaller than that of the first groove 104b, so that the metal sheet 106 can not be connected with the grounding wire when the conductive block 104d is not contacted, the first groove 104b and the second groove 104c are switched by rotating the grounding pile 104 by 90 degrees, when the grounding wire is needed, the first groove 104b and the metal sheet 106 are in the same plane, when the grounding wire is needed, the grounding pile 104 is rotated by 90 degrees around the circular hole 101a, and the second groove 104c and the metal sheet 106 are in the same plane, so that the swing rod 103 can be shifted to the grounding pile 104, and the metal sheet 106 is embedded in the second groove 104c to be separated from the conductive block 104 d.
