Abstract
The utility model discloses a high-voltage switch cabinet floor standing type handcart isolation contact arm. The high-voltage switch cabinet floor standing type handcart isolation contact arm comprises a guiding rod, a front end contact, an insulating rod, a back end contact, a spring and a fuse protector. The insulating rod is sleeved outside the fuse protector, the front end contact and the back end contact are respectively connected to the front end and the back end of the insulating rod, the guiding rod is connected with the front end contact, and the spring is arranged between the fuse protector and the back end contact. The high-voltage switch cabinet floor standing type handcart isolation contact arm is simple in structural design, few in detachable parts and high in reliability. The parts can be produced in standardized mode, and positioning is accurate in assembly.
Description
Technical field
The utility model relates to a kind of high-tension switch cabinet floor type handcart insulation contact arm.
Background technology
Element in high-tension switch cabinet, the appearance of new product is constantly arranged, to product technology, require more and more higher, and various special car products is more outstanding, the equipment fault caused because of low temperature, high temperature and make moist or that dewfall causes is creepage, the generation of flashover fault, and conventional special car product occurs that many problems are difficult to meet, as common, fully electrification in high voltage partly not to be wrapped, the inside is affected by dust, moisture, insect etc. also can.The user to high reliability, non-maintaining, change and to require easily also more and more urgently, market also calls new generation product to come out.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of high-tension switch cabinet floor type handcart insulation contact arm.
To achieve these goals, the technical solution of the utility model is as follows:
High-tension switch cabinet floor type handcart insulation contact arm, it is characterized in that, comprise guide post, front end contact, insulating bar, rear end contact, spring and fuse, described insulating bar is set in outside fuse, front end contact, rear end contact are connected to the front and back ends of insulating bar, described guide post is connected with the front end contact, and described spring is arranged between fuse and rear end contact.
In a preferred embodiment of the present utility model, be provided with inserts on described front end contact, described inserts is connected with insulating bar by holding screw.
In a preferred embodiment of the present utility model, be provided with inserts on the contact of described rear end, described inserts is connected with insulating bar by holding screw.
The beneficial effects of the utility model are:
1. have reliable electric connection: with common assembling, compare, the quantity of the parts of insulation contact arm, conductor faying surface, connection securing member all greatly reduces, thereby has simplified the assembling link of major loop, has improved the main conductive circuit connection reliability.The external environment of insulation contact arm drops to minimum on fuse impact, its insulating capacity can be avoided dust, moisture, toy, condensation and filth.
2. simple in structure: as can to adequately protect for fuse provides more, make it in assembling or transportation, avoid accidental mechanical and collide.
3. rationalize: adopt the insulation contact arm as dielectric, phase spacing can reduce the insulation distance of its current-carrying part.
4. convenient purification: because whole fuse is placed in the integral insulation contact arm, fuse has obtained adequately protecting, and has reduced the impact of environment, changes its fuse and facilitates easy.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained and be well understood to.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is that the utility model is applied to the schematic diagram on the high-tension switch cabinet floor type handcart.
Embodiment
