Problems solved by technology

[0002] In the 35KV armored removable metal-enclosed switchgear, the grounding switch is the main component, and its main function is to protect the grounding during equipment maintenance to ensure the safety of the human body and equipment; Arm operation mode; due to the large safety air distance between the fractures of the 35KV grounding switch, the distance between the moving and static contacts of the grounding switch is also large when it is disconnected, so the operating distance when the switch is closed and opened is long, so , the operation is very laborious when operating the grounding switch; moreover, if the assembly and adjustment of this method are not good, it is very easy to cause dead spots in the operation, which will affect the normal operation of the grounding switch

Embodiment 1

[0015] Embodiment 1, a grounding switch operating device for a removable switchgear, refer to figure 1 , figure 2 It is composed of a switch operating device and a mechanical interlocking device. The switch operating device is installed on the cabinet body at the front of the operating shaft 5. The tail is provided with a small bevel gear 11. The small bevel gear 11 meshes with the large bevel gear 6. The large bevel gear 6 It is connected with the main shaft 12 of the grounding switch, the large bevel gear 6 meshes with the interlocking small bevel gear 10, and the interlocking small bevel gear 10 is connected with the chain shaft 7 of the mechanical interlocking device. The structure of the mechanical interlocking device is the same as that of the prior art, which constitutes A structure of the present invention.

Embodiment 2

[0016] Embodiment 2, a grounding switch operating device for a removable switchgear, refer to figure 2 , image 3 , Figure 4 , Figure 5 , on the basis of Embodiment 1, the mechanical interlocking device is made up of the interlocking device in front of the cabinet and the interlocking device behind the cabinet, and the interlocking device in front of the cabinet is fixed with a front limiting plate 16 and a rear limiting plate at the front of the operating shaft 17. The valve curved plate 3 is installed between the cabinet body and the curved plate support 15, and is fixedly connected with the chain plate 1. The guide block 14 and the guide sleeve 13 are respectively installed in the chute of the valve curved plate 3 and the chain plate 1 and Connected with the cabinet body, the bracket 4 is fixed on the cabinet body, the bracket 4 is connected with the chain plate 1 through the tension spring 2, and the pressure plate 18 is fixed on the rear operation shaft 5 of the rear...

Embodiment 3

[0017] Embodiment 3, a grounding switch operating device for a removable switchgear, refer to figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , on the basis of Embodiment 2, an electrical interlocking device is provided in the cabinet. The device is composed of an auxiliary switch 19 and an electromagnetic locking iron 20. The auxiliary switch 19 has five sets of contacts: three normally open and two normally closed. A pressing plate 18 is fixed on the rear operating shaft 5 of the rear limiting plate 17. The pressing plate 18 contacts the top of the operating rod 23 of the auxiliary switch 19 through the backing plate 22. The up and down movement of the operating rod 23 realizes the conversion of each group of contacts. After the operating rod 23 moves downward to the position, the normally open contact of the auxiliary switch 19 is converted to normally closed, and the normally closed contact is converted to normally open; otherwise, if the downward pressure is r...

Abstract

The invention discloses a grounding switch operating device of a removable switch cabinet, which consists of a switch operating device and a mechanical linkage device, wherein in the switch operating device, the front part of an operating shaft is movably arranged on a cabinet body, the tail part of the operating shaft is provided with a small bevel gear mashed with a big bevel gear, the big bevel gear is connected with the spindle of a grounding switch and is meshed with a linkage small bevel gear, and the linkage small bevel gear is connected with the linkage shaft of the mechanical linkage mechanism. The device has the characteristics of turning off and on the grounding switch by using bevel gear transmission, realizing the off and on of the grounding switch by simply rotating a small angle, along with capability of being used in combination with various grounding switches, safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of armored removable metal-enclosed switchgear, in particular to an operating device for a grounding switch of a removable switch cabinet. Background technique [0002] In the 35KV armored removable metal-enclosed switchgear, the grounding switch is the main component, and its main function is to protect the grounding during equipment maintenance to ensure the safety of the human body and equipment; Arm operation mode; due to the large safety air distance between the fractures of the 35KV grounding switch, the distance between the moving and static contacts of the grounding switch is also large when it is disconnected, so the operating distance when the switch is closed and opened is long, so , the operator is just very laborious when operating the grounding switch; and, if the assembly adjustment is not good in this way, the operation dead point phenomenon will easily occur, which will affect the normal ope...
