Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.
[0022] like figure 1 As shown: this embodiment provides a circuit breaker handcart plug-in guide positioning and grounding structure, including: a guide grounding rod 1 installed on the partition board of the switch cabinet 4, and a guide grounding ring installed at the corresponding position on the chassis of the circuit breaker handcart 5 2. The guide grounding ring 2 cooperates with the guide ground rod 1; the guide ground ring 2 is connected with a plum blossom contact 3, and the plum blossom contact 3 and the guide ground rod 1 are in contact with each other. By setting up a guide grounding device between the switch cabinet 4 and the circuit breaker handcart 5, the problems of poor contact and grounding of the three-phase conductive contacts are solved, and t...

The invention discloses a plug-in guide positioning grounding structure for a circuit breaker handcart. The plug-in oriented positioning grounding structure for the circuit breaker handcart comprises guide grounding rods arranged on a partition plate of a switch cabinet, and guide grounding rings arranged at a corresponding position of a chassis of the circuit breaker handcart, wherein the guide grounding rings are mutually matched with the guide grounding rods, and plum contacts are connected onto the guide grounding rings and are contacted with the guide grounding rods in a mutually matched manner. Through erecting the guide grounding devices (the guide grounding rods, the guide grounding rings and the plum contacts) between the switch cabinet and the circuit breaker handcart, the problems of poor contact of a three-phase conductive contact and poor grounding are solved, the structure is simple, and the operation is convenient. The plug-in guide positioning grounding structure for the circuit breaker handcart is suitable for a withdrawable switch cabinet.
Description
technical field [0001] The invention relates to a grounding device, in particular to a circuit breaker handcart plug-in guide positioning grounding structure. Background technique [0002] Before the present invention was proposed, when the handcart of the circuit breaker was connected to the switch cabinet, the three-phase conductive contacts were generally aligned through the limitation of the handcart rails, but this alignment method was very inaccurate, and once there was a slight deviation, it would be Resulting in poor contact of the three-phase conductive contacts. At the same time, the grounding of the circuit breaker handcart is generally to add a grounding contact piece on the bottom of the chassis of the circuit breaker handcart. This sliding contact grounding method has the problem that if the pressure is insufficient, it will lead to poor grounding. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the ...
