Abstract
The utility model discloses a silica gel bottle lightning arrester for an electric switch, which comprises an upper electrode head, an umbrella skirt group, a lower electrode head and an insulating rod, wherein, an insulator is composed of the upper electrode head, the umbrella skirt group, the lower electrode head and the insulating rod. The utility model is also additionally provided with an annular variable resistor; the upper end of the insulating rod is provided with a snap ring which is provided with an installation handle, the outer side of which is coated with an insulating layer; the annular variable resistor is sheathed out of the insulating rod, and the outer layer of the annular variable resistor is coated with an insulating layer and is tightly locked by a flange. The umbrella skirt group is formed into integration, and the outer surface of the umbrella skirt group is moulded and pressed with silica gel. The utility model has the functions of lightning protection and overvoltage protection.
Description
The utility model relates to the electric component of the insulator switch that uses on the power transformer electric power system and lightning arrester combination.
Post insulator, lightning arrester and push-and-pull lock switching mechanism will be housed on the power transformer electric power system at present, and rack-layer is loaded down with trivial details, inconvenience is installed and operation.Existing Chinese patent 97220719 electric switches silicon rubber insulation bottle, it is a kind of insulator of simple function, mainly is made up of the cartridge that powers on, full skirt group, insulating rod and flange base.The full skirt group is formed by stacking by a plurality of full skirts, and it is to be one by the outer suit one full skirt group structure of epoxy insulation rod, but its function singleness.
The purpose of this utility model is a kind of electric switch of design silicon rubber bottle lightning arrester, has lightning-arrest and over-voltage protecting function.
The purpose of utility model is achieved in that the insulating bottle at simple function carries out architecture advances.This electric switch silicon rubber bottle lightning arrester, comprise the cartridge that powers on, full skirt group, bottom electrode head and insulating rod, wherein form an insulating bottle by the cartridge that powers on, full skirt group and bottom electrode head and insulating rod, it is characterized in that also having additional toroidal rheostat, the insulating rod middle part is provided with a snap ring, snap ring is provided with the installation handle, the handle outside is installed is surrounded by insulating barrier; Toroidal rheostat is enclosed within outside the insulating rod, and its skin is being surrounded by insulating barrier, and with flange locking, outside mold pressing silica gel full skirt group constitutes one.
This electric switch is with the shape of silicon rubber bottle lightning arrester former insulating bottle, at the Lower Half or the first half of insulating bottle the purpose that the ring-type variable resistor has reached lightning-arrest and overvoltage protection is housed.
Applicable on the RW3-11 series drop switch, protection equipment runs well this electric switch, is current desirable regeneration product with silicon rubber bottle lightning arrester.
The present invention is further described below in conjunction with embodiment and accompanying drawing.
Fig. 1, electric switch silica gel bottle lightning arrester example structure schematic diagram.
Fig. 2, electric switch silica gel bottle lightning arrester user mode schematic diagram.
Referring to Fig. 1, the present utility model is a kind of electric switch silicon rubber bottle lightning arrester, comprise the cartridge 1 that powers on, full skirt group 2, bottom electrode head 3 and insulating rod 4, wherein form an insulating bottle by the cartridge 1 that powers on, full skirt group 2 and bottom electrode head 3 and insulating rod 4, it is characterized in that also having additional toroidal rheostat 5, insulating rod 4 middle parts are provided with a snap ring 6, and snap ring 6 is provided with installs handle 7, handle 7 outsides is installed is surrounded by insulating barrier 8; Toroidal rheostat 5 is enclosed within outside the insulating rod 4, and its skin is surrounded by insulating barrier 9, and with flange 10 lockings, outside mold pressing silica gel full skirt group constitutes one; All have construction bolt 11 in power on cartridge 1 top and bottom electrode head 3 bottoms in addition.
Wherein toroidal rheostat 5 is made up of belt piezo-resistance stack.Full skirt group 2 is made up of 3～150 full skirts.
Referring to Fig. 2, during use, because the ring resistance sheet is housed in lightning arrester; resistor disc one termination is installed handle, and a termination bottom electrode head has constituted lightning arrester, when thunder and lightning produces electric arc; overvoltage flows into the earth, thereby plays the overvoltage protection effect by bottom electrode head, resistor disc, installation handle.
