Summary of the invention
The object of the present invention is to provide a kind of and support to form an integral body, the structure fastness is increased, dependability is good, and manufacture method is simply with the surge arrester support and the manufacture method of disconnector.The surge arrester support of this band disconnector, it comprises that one has the stake body of installing hole, the slotted eye of dress disconnector in stake body is provided with, the disconnector in the slotted eye is connected with lightning arrester by last binding post, is connected with ground wire by following binding post.
Described disconnector comprises at least one resistance that is placed directly in the slotted eye, one end of one contact spring is connected with last binding post, the other end contacts with resistance, one empty booster is embedded in the groove of resistance, one holddown spring is enclosed within on the sky booster and with following binding post and contacts, and following binding post is poured in the slotted eye of pallet body with epoxy resin.
The described binding post of going up is fixed in the slotted eye of stake body, and the resistance gap of packing into is placed directly in the slotted eye, and the leading section of empty booster is provided with the tip, and holddown spring is inserted at the place, tip, in the bottom cavity of the binding post down of packing into simultaneously.
Asbestos washer has been inserted in the outside of described empty booster, and following binding post contacts with asbestos washer.
A kind of surge arrester support method of making the band disconnector, it is that the insulated type plastics are put into particular manufacturing craft, under at least 110 ℃, pressure more than the 16Mpa, be pressed into a side and have the stake body that installing hole, opposite side are provided with slotted eye, to go up earlier that binding post is packed in the slotted eye and fixing, pack into successively then resistance, contact spring, empty booster, holddown spring and binding post down, and be poured in epoxy resin in the slotted eye of pallet body and will descend binding post to be fixed in the slotted eye of stake body.
Described insulated type plastics are after putting into particular manufacturing craft, be pressed into stake body under 120--200 ℃, 18----22Mpa pressure, in slotted eye, asbestos washer has been inserted in the outside of empty booster, and then will descend binding post to contact with asbestos washer, be fixed into one with the epoxy resin perfusion at last.
The invention belongs to a kind of improvement to prior art, it is owing to make integrative-structure with pallet body and disconnector, and it is simple to have manufacture craft, and cost is low, has increased structural strength, and simple installation is easy to maintenance, uses characteristics such as more reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in Figure 1, the present invention includes a stake body 2 that has an installing hole 1, the slotted eye 3 of dress disconnector in stake body 2 is provided with, the disconnector in the slotted eye 3 is connected with lightning arrester by last binding post 4, is connected with ground wire by following binding post 5.Described disconnector comprises that one directly is placed on the resistance 6 in the slotted eye 3, one end of one contact spring 7 is connected with last binding post 4, the other end contacts with resistance 6, one empty booster 8 is embedded in the groove of resistance 6, one holddown spring 9 is enclosed within on the sky booster 8 and with following binding post 5 and contacts, and following binding post 5 usefulness epoxy resin 10 are poured in the slotted eye 3 of pallet body 2.The described binding post 4 of going up is fixed in the slotted eye 3 of stake body, and resistance 6 gap 11 of packing into is placed directly in the slotted eye 3, and the leading section of empty booster 8 is provided with the tip, and holddown spring 9 is inserted at the place, tip, in the bottom cavity of the binding post 5 down of packing into simultaneously.Asbestos washer 12 has been inserted in the outside of described empty booster 8, and following binding post 5 contacts with asbestos washer 12.
The surge arrester support method of making band disconnector of the present invention, it is that the insulated type plastics are put into particular manufacturing craft, press down with upward pressure at least 110 ℃ of temperature, 16Mpa and to make a side and have the stake body that installing hole, opposite side are provided with slotted eye, to go up earlier that binding post is packed in the slotted eye and fixing, pack into successively then resistance, contact spring, empty booster, holddown spring and binding post down, and be poured in epoxy resin in the slotted eye of pallet body and will descend binding post to be fixed in the slotted eye of stake body.
Described insulated type plastics are after putting into particular manufacturing craft, be pressed into stake body under 120--200 ℃, 18----22Mpa pressure, in slotted eye, asbestos washer has been inserted in the outside of empty booster, and then will descend binding post to contact with asbestos washer, be fixed into one with the epoxy resin perfusion at last.Best temperature is that 160 ℃, pressure are 20Mpa.
Under normal operation operating state, there is not overvoltage in the electrical network, because the effect of lightning arrester MOA, the electric current that flows through in this mechanism only has microampere order, resistance is operated in cut-off region, is in off state.As running into abnormal conditions in the electrical network, produce overvoltage, the electric current that at this moment flows through among the lightning arrester MOA is very big; Because the resistance in this mechanism has been selected the ampere-time characteristic resistance suitable with lightning arrester MOA for use, therefore discharge capacity can satisfy fully, the electric current that resistance flows through is milliampere level just, as long as the resistance and the clearance distance of resistance are chosen suitably, just can satisfy the requirement of overvoltage condition, because compole is short when superpotential, the heat that resistance produces can not make the blast of sky booster at all, so disconnector can not move.When if lightning arrester MOA damages owing to aging or other reason cause, its voltage that mainly is reflected as lightning arrester MOA reduces, and leakage current increases, the leakage current of lightning arrester MOA increases, produce heat, when heat acquires a certain degree, will blast, cause operational failure.When Leakage Current increases, during lightning arrester operational failure, produce high voltage at the two ends of resistance, produce heat, because its time is longer, make the sky booster be subjected to thermal explosion, the disconnector running disconnects lightning arrester and working line, and the protection lightning arrester is not damaged.
Disconnector of the present invention also can adopt of the prior art any one, and it and stake body formed the integrative-structure form.
