Embodiment Construction
[0031] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0032]Embodiment 1 of the isolating switch of the present invention, such as Figure 1 to Figure 4 As shown, the isolating switch includes a housing 1 and a moving contact assembly and a static contact assembly installed in the housing 1. A transmission structure for driving the moving contact assembly to perform an insertion action is also installed in the housing 1. The static contact There is an isolation fracture between the head assembly and the moving contact assembly.
[0033] Such as figure 1 , figure 2 and image 3 As shown, the static contact assembly includes a static contact seat 2 and a contact finger assembly. The static contact seat 2 includes a columnar base 21, and the housing 1 is provided with a vertically arranged pot insulator 3. The columnar base 21 of the static contact seat 2 is fixed on the metal insert of the pot insulator ...

The invention relates to a static contact assembly and an isolation switch using the static contact assembly. The static contact assembly comprises a static contact seat and a contact finger assembly.The contact finger assembly comprises an annular support. A plurality of mounting groove structures are arranged on the annular support. Contact finger petals are mounted in the mounting groove structures. The contact finger petals extend out of the front end of the installation groove structure to form an insertion space for insertion of an adaptive contact. The static contact seat comprises a columnar base body. A mounting ring groove is formed in the front end of the columnar base body. The rear ends of the contact finger petals are inserted into the mounting ring grooves. The rear ends ofthe contact finger petals are provided with spherical convex parts. The static contact assembly further comprises baffle ring structures located on the outer sides of the contact finger petals, elastic reeds are arranged between the baffle ring structures and the contact finger petals in a clamped mode, and the static contact seat is further provided with a stopping structure for preventing the contact finger petals from disengaging from the front side of the installation ring groove. And the contact finger petals can swing by taking the spherical convex parts as fulcrums, so that automatic centering of the contact finger petals and the adaptive contact is realized.
Description
technical field [0001] The invention relates to a static contact assembly and a disconnector using the static contact assembly. Background technique [0002] Gas-insulated metal-enclosed switchgear (GIS), as the basic equipment of the power system, has gradually won the trust of the market due to its high parameters, integration, and stable operation. As one of the important components of GIS equipment components, the isolation switchgear is used to reliably isolate the power supply in the power system. When the isolating switch is in the closed state, the conductive system can pass the normal working current and the short-circuit current under fault; when the isolating switch is in the open state, the isolation fracture is not allowed to have insulation breakdown in any state. [0003] The authorized announcement number is CN202454478U, and the authorized announcement date is 2012.09.26. The Chinese utility model patent discloses a three-position switch. The three-position...
