At present, when the connected mode of this Disconnecting switch unit has determined that this unit uses separately the isolating switch function, grounded part can only be removed, change and do the conductor connection, the volume of this Disconnecting switch unit is larger on the one hand, element length 1200mm, accompanying drawing 2, can only laterally dock as shown in Figure 1 when Disconnecting switch unit docks with other functional units on the other hand, must cause the combined electrical apparatus overall width to strengthen, floor space strengthens, and interval width is 2810mm, such as Fig. 3 (this figure is that Disconnecting switch unit is installed in the state on the combined electrical apparatus), this connected mode can not satisfy on-the-spot installation and the higher demand of power industry development.
The utility model content
The purpose of this utility model is to provide a kind of improved Disconnecting switch unit, this Disconnecting switch unit not only can be realized isolation fracture, ground connection and independent two kinds of functions of isolation fracture, and installation dimension is little, and the user can install flexibly according to different demands.
The technical scheme in the invention for solving the technical problem is:
A kind of improved Disconnecting switch unit, comprise Disconnecting switch unit shell, Disconnecting switch unit operating mechanism, moving contact and fixed contact, be provided with adpting flange at the Disconnecting switch unit shell, described Disconnecting switch unit operating mechanism drives described moving contact, it is characterized in that described Disconnecting switch unit shell has been set up three adpting flanges altogether at its left side, right side, downside; Described Disconnecting switch unit comprises the improved Disconnecting switch unit operating mechanism of a cover, a cover moving contact, and described moving contact matches with improved static contact isolation switch, improved static contact of grounding switch respectively; Be provided with support between described improved static contact of grounding switch and the Disconnecting switch unit shell.
Described support is metallic conductor.Moving contact matches with improved static contact isolation switch, improved static contact of grounding switch respectively, can realize the mutual switching of isolating switch and earthed switch.
Described support is insulator.Moving contact matches with improved static contact isolation switch respectively, can realize independently isolation fracture function.When isolating switch disconnects, improved static contact of grounding switch will alleviate as buffering stand the wearing and tearing of moving contact.
Compare with original structure, the beneficial effects of the utility model are:
1, improved Disconnecting switch unit only needs can realize isolating switch and grounding function once cover operating mechanism and a cover moving contact, two cover fixed contacts that structure is simplified.
2, improved Disconnecting switch unit has been set up three adpting flanges at its left side, right side, downside respectively, can install flexibly according to the different demand of user.When docking with other unit, can realize laterally docking and vertically docking.This isolated location length becomes present 930mm by original 1200mm, and the combined electrical apparatus width after installing becomes present 740mm by original 2810mm.The installation dimension of improved unit is reduced to full-sized about 1/4, thereby floor space is little, and cost is low, satisfies easily on-the-spot requirements of installation space.
3, this Disconnecting switch unit can be realized isolation fracture, ground connection and independent two kinds of functions of isolation fracture.Be that static contact of grounding switch just can be realized different functions from the support change material of shell junction, when saving lot of materials, reduce land use area, can satisfy the higher level demand of client.
4, this Disconnecting switch unit can be realized the mutual switching of isolating switch and earthed switch, thereby has realized the mechanical latching function of isolating switch and earthed switch, and unfailing performance improves.And former Disconnecting switch unit can not be realized this function.

Embodiment
Such as Fig. 4-Fig. 6. improved Disconnecting switch unit 1, only have once the improved Disconnecting switch unit operating mechanism 6 of cover, a cover moving contact 17, the improved static contact isolation switch 14 of two covers and can realize isolating switch and grounding function.
Improved Disconnecting switch unit 1 has respectively been set up an adpting flange at its left side, right side, downside respectively, can install flexibly according to the different demand of user.When docking with other unit, can realize laterally docking each place about 8(by the adpting flange of left side, right side, downside) and vertically docking 9.
Owing to adopt such scheme, so that the length of Disconnecting switch unit 1 becomes 930mm (accompanying drawing 5) after the improvement by original 1200mm (accompanying drawing 2), and the combined electrical apparatus width after installing becomes 740mm (accompanying drawing 6) after the improvement by original 2810mm (accompanying drawing 3).The installation dimension of improved unit is reduced to full-sized about 1/4; Floor space is little, and cost is low.
This Disconnecting switch unit 1 can realize that the locking of isolation fracture, ground connection is switched mutually and independent two kinds of functions of isolation fracture.Mainly just can realize by support 16 materials that change improved static contact of grounding switch 15 and Disconnecting switch unit shell 13 junctions.
When these support 16 materials were metal material, improved static contact of grounding switch 15 linked to each other with the earth by earthing device with this shell of Disconnecting switch unit shell 13(by this metal material) be connected the function that can be grounded.During work, improved Disconnecting switch unit operating mechanism 6 drives moving contacts 17 and is rotated motion, is 60 ° from being incorporated into minute anglec of rotation, when moving contact 17 with after improved static contact isolation switch 14 contacts, can realize the isolating switch function; When moving contact 17 with after improved static contact of grounding switch 15 contacts, be grounded function.This structure can realize the mutual switching of isolating switch and earthed switch by improved Disconnecting switch unit operating mechanism 6, thereby has realized the mechanical latching function of isolating switch and earthed switch, and unfailing performance improves.
When these support 16 materials were insulating material, insulation lost grounding function, thereby realizes independently isolation fracture function between improved static contact of grounding switch 15 and the Disconnecting switch unit shell 13.When isolating switch disconnects, improved static contact of grounding switch 15 will alleviate as buffering stand the wearing and tearing (static contact of grounding switch inside is comprised of spring and many copper little fingertips, and spring can play the effect of buffering) of moving contact 17.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
