Abstract
An outdoor isolating switch is provided. The outdoor isolating switch mainly solves a problem of an existing isolating switch that an elastic clamping piece is easily burned or to lose elasticity under electric arc effect. The outdoor isolating switch comprises a mounting seat (1), insulators (2), an input electrode (3), an output electrode (4) and a knife switch (5), wherein the input electrode (3) is provided with an elastic clamping piece (6), the insulators (2) are fixed on the mounting seat (1), and an end of the knife switch (5) is hinged to the output electrode (4); and the outdoor isolating switch is characterized in that an end tab (7) is electrically connected on the input electrode (3), and the end tab (7) is positioned on a side position below the elastic clamping piece (6). The outdoor isolating switch is added with the end tab, and the electric arc is further away from the elastic clamping piece when breaking the knife switch, so no influence will be generated to the elasticity of the elastic clamping piece; the end tab pulls away the electric arc to protect the elastic clamping piece, and prevents the electric arc from burning the elastic clamping piece and thus causes contact failure; and the isolating switch is reliable in electric connection and long in service life.
Description
Technical field
The utility model relates to a kind of high-voltage switch electric appliance, is specifically related to a kind of outdoor disconnector.
Background technology
High voltage isolator refers to that rated voltage at 1kv and above isolating switch thereof, abbreviates isolating switch as usually, is the high-voltage switch electric appliance of using always, its operation principle and relatively simple for structure, but because use amount is big, functional reliability requires high.Existing isolating switch mainly is made up of mount pad, insulator, input electrode, output electrode and plug-in strip, input electrode is provided with the elastic clip of clamping plug-in strip, one end and the output electrode of plug-in strip are hinged, during use, promote plug-in strip plug-in strip is entered in the elastic clip, and then conducting transmission of electricity circuit.There is following technological deficiency in this isolating switch: when the disjunction plug-in strip, can produce electric arc between plug-in strip and the elastic clip, because no arc extinguishing ability, electric arc can make elastic clip produce high temperature, causes the elasticity of elastic clip to weaken, even follows the string or burn, when closing a floodgate again, the chucking power of elastic clip clamping plug-in strip reduces, and influences the electrical connection properties between elastic clip and the plug-in strip, and useful life is short.
The utility model content
The problem that easily under arcing, follows the string or burn for the elastic clip that overcomes in the existing isolating switch; the utility model provides a kind of outdoor disconnector; this outdoor disconnector has increased the striking sheet; during the disjunction plug-in strip, electric arc from elastic clip away from, can the elasticity of elastic clip not exerted an influence; run-on tab has drawn back electric arc; protected elastic clip, prevented that electric arc from burning elastic clip and cause loose contact, had the advantages that to be electrically connected reliable and long service life.
The technical solution of the utility model is: a kind of outdoor disconnector, comprise mount pad, insulator, input electrode, output electrode and plug-in strip, input electrode is provided with elastic clip, insulator is fixed on the mount pad, one end of plug-in strip is hinged on the output electrode, be electrically connected with run-on tab on the described input electrode, run-on tab is positioned at the side-lower of elastic clip.
One end of described run-on tab is fixed on the insulator, other end bending and oblique the stretching out of run-on tab.
The utlity model has following beneficial effect: owing to take such scheme; during the disjunction plug-in strip; the upper end of plug-in strip and run-on tab close together; the electric arc that produces between plug-in strip and the elastic clip is pulled on the run-on tab rapidly; this moment electric arc from elastic clip away from; the temperature of elastic clip is raise; not influence of elasticity to elastic clip; because run-on tab has drawn back electric arc; protected elastic clip, prevented that electric arc from burning elastic clip and cause loose contact, again during closed plug-in strip; plug-in strip still can be electrically connected long service life reliably with maintenance between the elastic clip.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
1-mount pad among the figure, 2-insulator, 3-input electrode, 4-output electrode, 5-plug-in strip, 6-elastic clip, 7-run-on tab.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of outdoor disconnector, comprise mount pad 1, insulator 2, input electrode 3, output electrode 4 and plug-in strip 5, input electrode 3 is provided with elastic clip 6, elastic clip 6 also claims fixed contact, and insulator 2 is fixed on the mount pad 1, and an end of plug-in strip 5 is hinged on the output electrode 4, be electrically connected with run-on tab 7 on the described input electrode 3, run-on tab 7 is positioned at the side-lower of elastic clip 6.Owing to take technique scheme; during disjunction plug-in strip 5; the upper end of plug-in strip 5 and run-on tab 7 close together; the electric arc that produces between plug-in strip 5 and the elastic clip 6 is pulled to rapidly on the run-on tab 7; this moment electric arc from elastic clip 6 away from; the temperature of elastic clip 6 is raise; not influence of elasticity to elastic clip 6; because run-on tab 7 has drawn back electric arc; protected elastic clip 6, prevented that electric arc from burning elastic clip 6 and cause loose contact, during again closed plug-in strip 5; plug-in strip 5 still can be electrically connected long service life reliably with maintenance between the elastic clip 6.
One end of described run-on tab 7 is fixed on the insulator 2, the bending of the other end of run-on tab 7 and oblique stretching out.When drawing back plug-in strip 5, the close together between plug-in strip 5 and the run-on tab 7 is beneficial to arcing, effectively avoids electric arc that elastic clip 6 is caused damage.
Claims (2)
1. outdoor disconnector, comprise mount pad (1), insulator (2), input electrode (3), output electrode (4) and plug-in strip (5), input electrode (3) is provided with elastic clip (6), insulator (2) is fixed on the mount pad (1), one end of plug-in strip (5) is hinged on the output electrode (4), it is characterized in that: be electrically connected with run-on tab (7) on the described input electrode (3), run-on tab (7) is positioned at the side-lower of elastic clip (6).
2. outdoor disconnector according to claim 1, it is characterized in that: an end of run-on tab (7) is fixed on the insulator (2), the bending of the other end of run-on tab (7) and oblique stretching out.
