Description
Technical field
The utility model relates to a kind of column support type metal oxide arrester that is used for the high-tension line cable, particularly a kind of column support type series gap metal oxide arrester.
Background technology
The column support type insulator that generally is used for the high-tension line cable support of 10kV distribution system, owing to be in outdoor nature for a long time, after being subjected to the infringement of various dunghills such as rainwater, dust, cigarette ash, chemical substance, insulation level descends, meet with thunderbolt as circuit this moment, the very easy flashover relatively that causes of insulator outer surface is simultaneously because the effect of power frequency arc can make aluminium matter cable breakage cause systematic failures to the high temperature that lead produces.A kind of column support type gapless metal-oxide lighting arrester is arranged in the prior art, see Fig. 3, it is a reinforced insulation pipe (8) that is wrapped in the organic composite sheath of silicon rubber (7), its upper end has end cap (2) to connect binding post (1), the lower end has base (10) to connect securing member (11), and stacked successively from top to bottom aluminium electrode block (3), resistor disc (6) and the following aluminium electrode block (9) gone up of its inner chamber.Can solve the thunderbolt problem that meets with.But it remains in following problems:
1. resistor disc bears power-frequency voltage for a long time, more easily produces aging phenomenon, has reduced the useful life of lightning arrester.
2. owing to lightning arrester isolation very close to each other, zinc oxide resistance sheet is limited by chargeability, must reach certain reference voltage level during design, and the lightning impulse current residual voltage of the distribution type lightning arrester of this moment will reach nearly 50kV, and the protection level still belongs to generally.
The utility model content
The purpose of this utility model is to provide a kind of impulse current residual voltage lower; the atmospheric over-voltage protection characteristic is better; and can make the column support type series gap metal oxide arrester that post insulator uses; this lightning arrester impulse sparkover voltage and nominal discharge current residual voltage value all can reach the 40kV level that is not more than; to satisfy the normal operation of 10kV distribution system aerial cable and equipment, avoid the thunderbolt infringement.
For achieving the above object, the utility model adopts following technical proposals:
A kind of column support type series gap metal oxide arrester, the reinforced insulation pipe that is comprising composite sheath, its upper end has end cap to connect binding post, the lower end has base to connect fastener, and stacked successively from top to bottom aluminium electrode block, resistor disc and the following aluminium electrode block gone up of its inner chamber is characterized in that a discharging gap member is arranged between aluminium electrode block and the resistor disc.
To be that the linear resistance ring made by two metal thin-wall bowls up and down and anti-aging inorganic material is superimposed constitute above-mentioned discharging gap member, the bottom surface of two metal thin-wall bowls constitutes effective discharging gap in the linear resistance ring inner chamber distance of remaining valid.
Between above-mentioned discharging gap member and the last aluminium electrode block spring is arranged.
Above-mentioned resistor disc is three stacked zinc oxide resistance sheets; Described composite sheath is that silicon rubber has mantle.
The utility model compared with prior art, have following conspicuous characteristics and advantage: the utility model is being provided with a discharging gap member between aluminium electrode block and the resistor disc on the existing column support type metal oxide arrester, band series connection face gap metal oxide lightning arrester is combined with the function of column support type composite insulator, make the 10kV ultra-high-tension power transmission line reach lightning protection effect preferably, because lightning arrester has series gap and isolates, non-linear resistor does not directly bear long-term power-frequency voltage, can prolong the useful life of lightning arrester.Because of the isolation in gap, can design lowlyer the nominal impulse current residual voltage of lightning arrester (being not more than 40kV) simultaneously, make the lightning protection effect of circuit more obvious, system's operation be safer, reliable.

Embodiment
A preferred embodiment of the present utility model is: referring to Fig. 1, this column support type series gap metal oxide arrester, include a reinforced insulation pipe 8 that is wrapping composite sheath 7, its upper end has end cap 2 to connect binding post 1, the lower end has base 10 to connect securing member 11, and the stacked successively from top to bottom aluminium electrode block 3 of going up of its inner chamber, discharging gap member 5, resistor disc 6 and following aluminium electrode block 9, to be that the linear resistance ring made by two metal thin-wall bowls 13 up and down and anti-aging inorganic material 12 is superimposed constitute described discharging gap member 5, the bottom surface of two metal thin-wall bowls 13 constitutes effective discharging gap in the linear resistance ring 12 inner chambers distance of remaining valid.Above-mentioned resistor disc 6 is a zinc oxide resistance sheet; Above-mentioned composite sheath 7 has mantle for silicon rubber.In the manufacturing process engineering, aluminium electrode block 3, linear resistance ring 12, resistor disc 6 and following aluminium electrode block 9 external cylindrical surfaces and reinforced insulation pipe 8 inwall close-fittings are merged they are contacted up and down stacked pressing.
Another embodiment of the present utility model is: referring to Fig. 2, this column support type series gap metal oxide arrester is same as the previously described embodiments basically, different is between discharging gap member 5 and the last aluminium electrode block 3 spring 4 to be arranged, aluminium electrode block 3, linear resistance ring 12, resistor disc 6 and following aluminium electrode block 9 external cylindrical surfaces and reinforced insulation pipe 8 inwalls and guarantee that by spring 4 they stackedly up and down press contact movingly on it.
The electric loop of the utility model lightning arrester is: high-voltage connection terminal 1-goes up aluminium electrode 9-ground connection under the aluminium electrode 3-spring 4-discharging gap 5-resistor disc 6-.
When system normally moved, this column support type lightning arrester was in state of insulation substantially, only played the post insulator effect in system, supported and fixing high voltage overhead cable.When transmission line is struck by lightning, higher surge voltage is immediately by binding post and last aluminium electrode, be passed to the gap, and puncture the gap rapidly, surge voltage is passed to resistor disc, because metal oxide resistance has very good voltage-current characteristic, higher surge voltage reduces the resistor disc resistance rapidly, lightning current promptly flows into the earth by resistor disc 6, following aluminium electrode 9, and the utility model of this moment will play lightning arrester.Thunderbolt resistor disc resistance later promptly returns to original basic insulation state.
