Problems solved by technology

[0006] However, the existing technology has the following defects when it is applied to the solid-sealed pole made of thermoplastic materials: the end cover has poor strength and cannot bear the effect of dozens of times the atmospheric strength applied when making the pole. , the end cap of the vacuum switch tube will be obviously sunken under the action of injection molding pressure, so that the function of the vacuum switch tube will be lost

Embodiment 1

[0030] This preferred embodiment provides a vacuum switch tube, such as figure 2 with image 3 As shown, it includes an insulating shell 1, the two ends of the insulating shell 1 are respectively provided with end caps 2, and the inner sides of the two end caps 2 are provided with a reinforcing structure 3, and the reinforcing structure 3 is used to support the end when making a thermoplastic solid-sealed pole. Cover 2. The reinforcement structure 3 is preferably but not limited to be made of steel, and may also be other materials with appropriate strength.

[0031] The vacuum switch tube provided in this embodiment is provided with a reinforcing structure 3 supporting the end cover 2 when making a thermoplastic solid-sealed pole. When making a thermoplastic solid-sealed pole, the vacuum interrupter must withstand tens of times the atmospheric pressure , the reinforcing structure 3 can avoid the problem of the function loss of the vacuum interrupter caused by the serious co...

Abstract

The invention discloses a vacuum switch tube and a vacuum switch, and belongs to the technical field of vacuum switches. The vacuum switch tube and the vacuum switch are designed for solving the problems that an end cover in an existing structure is easy to damage and the like when a thermoplastic solid-sealed polar pole is produced. The vacuum switch tube comprises an insulated enclosure, and end covers are separately arranged at two ends of the insulated enclosure; a reinforcing structure is arranged on the inner side of at least one end cover and is used for supporting the end cover when the thermoplastic solid-sealed polar pole is produced. The invention also provides a vacuum switch comprising the vacuum switch tube. According to the vacuum switch tube and the vacuum switch provided by the invention, when the thermoplastic solid-sealed polar pole is produced and a vacuum quenching pot needs to bear dozens of times of atmospheric pressure, the problem of function loss of the vacuum quenching pot caused by serious deformation of the end covers can be solved by the reinforcing structure of the vacuum switch tube, and the structure and the performance of the vacuum switch keep stable and reliable.

Description

technical field [0001] The invention relates to the technical field of vacuum switches, in particular to a vacuum switch tube and a vacuum switch provided with the vacuum switch tube. Background technique [0002] In the distribution network, the switchgear that plays a control or protection function is an important device that must be applied in the circuit, and it plays the role of closing and breaking the circuit. In recent years, due to the obvious advantages of the vacuum switch (strong breaking capacity, environmental protection and no explosion hazard, small contact gap, extremely high electrical life, etc.), it has occupied an overwhelming position in the application of the medium voltage field. [0003] The core component of the vacuum switch is the vacuum switch tube in the housing. The structure of the existing conventional vacuum switch tube is as follows figure 1 as shown, [0004] Including the insulating shell 1, the two ends of the insulating shell 1 are r...
