Embodiment 1

[0020] The auxiliary switch for the grid transformer is composed as follows: an upper end cover assembly 1, a lower end cover assembly 2, an insulating mounting plate 3, an indicator pin 4, a contact piece 5, a contact assembly 6 and a shaft assembly 8; the insulating mounting plate 3 is located at the upper end Between the cover assembly 1 and the lower end cover assembly 2, the shaft assembly 8 runs through the insulating mounting plate 3, the indicator pin 4 is connected to one end of the shaft assembly 8, the contact assembly 6 is set on the shaft assembly 8, the contact piece 5 and the contact Components 6 are connected. The indicator needle 4 can realize the selection status of the shaft assembly in real time, so as to understand the on-off status of the contact piece 5 .

[0021] The one contact assembly 6 is connected with 2-4 contact pieces 5 .

[0022] 1-10 contact assemblies 6 are sleeved on the shaft assembly 8 .

[0023] The number of contact pieces 5 and contac...

Embodiment 2

[0029] This embodiment is basically the same as Embodiment 1, the difference is:

[0030] The one contact assembly 6 is connected to two contact pieces 5 .

[0031] A contact assembly 6 is sleeved on the shaft assembly 8 .

Embodiment 3

[0033] This embodiment is basically the same as Embodiment 1, the difference is:

[0034] The one contact assembly 6 is connected to three contact pieces 5 .

[0035] Ten contact assemblies 6 are sleeved on the shaft assembly 8 .

Abstract

The invention discloses an auxiliary switch for a power grid transformer. The switch comprises an upper end cover assembly, a lower end cover assembly, an insulating installation plate, an indicator hand, a contact sheet, a contact assembly, and a shaft assembly. The insulating installation plate is located between the upper end cover assembly and the lower end cover assembly. The shaft assembly is arranged through the insulating installation plate. The indicator hand is connected with one end of the shaft assembly. The contact assembly is installed on the shaft assembly. The contact sheet is connected with the contact assembly. The switch is a mechanical structure switch, and thus the stroke switch is high in reliability, simple in structure, and stable in performance, and has a broad market prospect. The switch can work stably between -55 and 70 DEG C. Test indices of the switch meets related requirements of GB 14048.5. The switch has large market and social value.

Description

technical field [0001] The invention relates to the technical field of structural design and application of an auxiliary switch, and in particular provides an auxiliary switch for a power grid transformer. Background technique [0002] The existing auxiliary switches for transformers are large in volume and weak in anti-vibration capability, and the number of switch groups cannot be adjusted. [0003] People are eager to obtain an auxiliary switch for power grid transformer with excellent technical effect. Contents of the invention [0004] The purpose of the present invention is to provide an auxiliary switch for power grid transformer with excellent technical effect. It is used for simultaneous "on" and "off" conversion of multiple branches of the power grid transformer. [0005] The auxiliary switch for the grid transformer is composed as follows: an upper end cover assembly 1, a lower end cover assembly 2, an insulating mounting plate 3, an indicator pin 4, a contact...
