Description

Technical Field

[0001] The utility model relates to the technical field of arc extinguishing chambers, and more specifically, to a new type of arc extinguishing chamber isolation device. Background Technique

[0002] An arc is a gas discharge phenomenon. The existence of the arc prolongs the time of the circuit path, exacerbates the harm of power system failures, and the arc sparks may also cause breakdown damage to some electronic products along with the circuit.

[0003] A moving conducting rod is arranged in the arc extinguishing chamber. The moving conducting rod is connected to a moving contact and drives the moving contact to move so that it fits with the static contact. However, during the movement of the moving conducting rod, wear is likely to occur at the opening and between the moving conducting rod and the bellows. Therefore, it is necessary to improve it to increase the service life of the bellows and the moving conducting rod. Summary of the Utility Model

[0006] (2) Technical Solutions

[0007] To achieve the problems raised above, the specific technical solutions adopted by the utility model are as follows:

[0008] A new type of arc extinguishing chamber isolation device includes a ceramic housing. A through groove is provided on the top surface of the ceramic housing, and a guiding conducting rod is arranged in the through groove. A wear-resistant sleeve is arranged between the guiding conducting rod and the through groove, and a bellows is sleeved outside the guiding conducting rod. A shielding layer is arranged on the guiding conducting rod and is located in the through groove.

[0009] Further, a clamping block is arranged on the outer surface of the ceramic housing, and the clamping block is clamped in a clamping groove. The clamping groove is opened on one side surface of the protective sleeve.

[0010] Further, a static conducting rod is inserted into the through groove, and a sealing ring is arranged between the static conducting rod and the through groove.

[0011] Further, one end of the guiding conducting rod is connected to a dynamic conducting contact. A guiding block is arranged on one side surface of the dynamic conducting contact. The guiding block is clamped in a guiding groove, and the guiding groove is opened on one side surface of the static conducting contact. One end of the static conducting contact is connected to a static conducting rod.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present utility model provides a new arc extinguishing chamber isolation device, which has the following beneficial effects:

[0016] (1) In the present utility model, a through groove, a wear-resistant layer, a sealing ring, a protective sleeve, a guiding block and a guiding groove are adopted. During actual use, the wear-resistant layer arranged between the through groove and the guiding electric rod ensures that the moving electric rod does not directly contact the opening during the moving process, and the wear resistance is improved through the wear-resistant layer, avoiding direct contact with the dynamic electric rod, thereby improving the service life of the dynamic electric rod. Through the arranged guiding block and guiding groove, a guiding effect can be achieved during the opening and breaking process, preventing the poor contact between the contacts after the contacts are worn due to long-term use. By arranging the sealing ring for sealing, the sealing performance and protection performance are further improved.
