Technical Field

The invention relates to the technical field of high-voltage electrical appliance switches, in particular to a switch device.

Background

In distribution equipment, when two sets of production lines share a power supply, mutual interference easily occurs, and particularly in the production process of polycrystalline silicon, the interference of a reduction furnace in the high-voltage breakdown process can affect other reduction furnaces which normally run, so that a precise control system is mistakenly turned off, and the breakdown fault of a vacuum tube of a contactor can be caused by the superposition of voltage, thereby affecting the production progress and the product quality. In order to eliminate potential safety hazards as much as possible, a common high-voltage breakdown power supply needs to be isolated so as to achieve the purpose of eliminating the interference of the starting of one production line on another production line. At present, it is common to arrange separate isolation switches in different production lines, and to shut down one production line when another production line starts working, so as to prevent interference between the two production lines and meet the process production requirements. However, the above method is prone to cause operator errors, especially when the operator performs the switching operation between the two production lines, and the operator is prone to cause equipment parking accidents.

In order to achieve the purpose, the invention adopts the following technical scheme:

a switching device, comprising: the transmission rod is movably connected with the two connecting rods at two opposite sides in the axial direction, and when the transmission rod moves in the axial direction, the conductive rods also move in the circumferential direction along with the separation knife to enable the separation knife to be in contact with or separated from the conductive contact parts; when one isolating knife is in a contact state with one conductive contact part, the other isolating knife is in a separation state with the other conductive contact part.

Preferably, the transmission rod and the plane where the axes of the two conducting rods are located together are parallel to each other, and the isolating knife and the conducting rods are perpendicular to each other; wherein one of the isolation knives intersects the other of the isolation knives.

Preferably, an included angle between a plane where a line segment between an end of the connecting rod and one of the conductive rods is located and the isolating knife, which are arranged on one of the conductive rods, is different from an included angle between a plane where a line segment between an end of the connecting rod and the other of the conductive rods is located and the isolating knife, which are arranged on the other of the conductive rods.

Preferably, the two connecting rods are respectively disposed on ends of the two conductive rods relatively close to each other.

Preferably, the angle between the connecting rod and the conducting rod is 90 °.

Preferably, the conductive contact portion includes a plurality of contacts arranged in an array, and an arrangement direction of the plurality of contacts is parallel to an axial direction of the conductive rod.

Preferably, the isolating blade comprises a plurality of contact arms arranged in an array, each two adjacent contact arms are parallel to each other, and each contact arm is in contact with or separated from one corresponding contact.

Preferably, the transmission rod is provided with an operating rod for pushing the transmission rod to enable the transmission rod to move in the axial direction.

Preferably, an insulating handle is arranged on the free end of the operating rod.

When the switch device is used as a common switch of two production lines (namely a circuit) sharing one power supply, the opening of one production line and the closing of the other production line can be completed in the same switch operation, so that an interlocking structure is formed between the two production lines, and the possibility of misoperation of workers is prevented.
