Product Introduction
V(VS1)-12 fixed indoor high-voltage vacuum circuit breaker is an indoor switchgear for three-phase AC 50Hz rated voltage 12kV power system, as a protection and control unit for power grid equipment and power equipment in industrial and mining enterprises. It is suitable for places that require frequent operation at rated working current, or break short-circuit current for many times.The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.
- Top Section: Three cylindrical protrusions are present. The left and right ones are symmetric, each with a width dimension of 210 mm (as marked above them). The middle protrusion is accompanied by a fin - like structure, likely for heat dissipation.
- Vertical Dimensions: The total height of the device is 580 mm. The lower rectangular panel section measures 442 mm in height, while the upper part is segmented into two parts: 206 mm (upper - upper) and 416 mm (upper - lower, related to the knob position).
- Horizontal Dimensions: The overall width at the base is 588 mm, with the inner panel width being 520 mm. The center - to - center distance between the two circular knobs on the panel is 140 mm.
1. Dimensional Layout
- Horizontal: The total width is 437 mm, divided into a 275 - mm left section and an 115 - mm right section.
- Vertical: On the left side, two height segments are marked: 275 mm (upper) and 237 mm (lower), defining the component's vertical proportions.
2. Component Features
- Left Side: A vertical cylindrical structure is visible, with a spring - like element at its base (suggesting flexibility or shock absorption).
- Right Side: A rectangular enclosure features two circular mounting holes (indicated by cross - sectional circles).
3. Detail View ("A Direction")
- An auxiliary view labeled "A Direction" (with an arrow indicating the viewing angle) shows a threaded hole specification:
- Thread: M18×2.5 (metric thread, 18 mm diameter, 2.5 mm pitch),
- Depth: 18 mm (how far the thread extends into the component).
