Abstract
The utility model discloses a lightning arrester with a stanchion silica gel isolator isolating switch, which comprises an upper electrode head, an umbrella skirt group, a lower electrode head and an insulating rod, wherein, an insulating bottle is composed of the upper electrode head, the insulating rod, the lower electrode head and the umbrella skirt group. The utility model is characterized in that the utility model is also additionally provided with an annular variable resistor which 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 silica gel umbrella skirt group is pressed outside and forms into integration. The utility model is used in the isolating switch, and one of the insulators is replaced by the utility model which has the functions of lightning protection and over voltage protection.
Description
The utility model relates to the electric component of the post insulator that uses on the power transformer electric power system and lightning arrester combination.
On the power transformer electric power system post insulator, lightning arrester and isolating switch will be housed at present, 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 consist of one by epoxy insulation rod overcoat full skirt, but its function singleness.
The purpose of this utility model is the sub-isolating switch lightning arrester of a kind of pillar silicone insulation of design, has lightning-arrest and over-voltage protecting function, and it uses on isolating switch.
The purpose of utility model is achieved in that the insulating bottle at simple function carries out architecture advances.The sub-isolating switch lightning arrester of this pillar silicone insulation, comprise the cartridge that powers on, full skirt group, bottom electrode head and insulating rod, wherein constitute an insulating bottle by the cartridge that powers on, insulating rod, bottom electrode head and full skirt group, it is characterized in that also having additional toroidal rheostat, toroidal rheostat is enclosed within outside the insulating rod, its skin is being surrounded by insulating barrier, and with flange locking, outside mold pressing silica gel full skirt group constitutes one.
The sub-isolating switch lightning arrester of this pillar silicone insulation keeps the shape of former insulating bottle, is set with the purpose that the ring-type variable resistor has reached lightning-arrest and overvoltage protection in the insulating rod outside.
The sub-isolating switch lightning arrester of this pillar silicone insulation is used on the isolating switch, and it can run well by protection equipment, is current desirable regeneration product.
The present invention is further described below in conjunction with embodiment and accompanying drawing.
Fig. 1, the sub-isolating switch lightning arrester of pillar silicone insulation example structure schematic diagram.
Fig. 2, the sub-isolating switch lightning arrester of pillar silicone insulation user mode schematic diagram on isolating switch.
Referring to Fig. 1, the sub-isolating switch lightning arrester of the utility model pillar silicone insulation, comprise the cartridge 1 that powers on, full skirt group 2, bottom electrode head 3 and insulating rod 4, wherein constitute an insulating bottle by the cartridge 1 that powers on, insulating rod 4, bottom electrode head 3 and full skirt group 2, it is characterized in that also having additional toroidal rheostat 5, toroidal rheostat 5 is enclosed within outside the insulating rod 4, and its skin is being surrounded by insulating barrier 6, with flange 7 lockings, outside mold pressing silica gel full skirt group 2 constitutes one.
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; when on isolating switch, using; substitute one of them insulator with it; because the insulating rod in the sub-isolating switch lightning arrester of pillar silicone insulation is set with the ring resistance sheet outward; the resistor disc one end cartridge that powers on, a termination bottom electrode head has constituted lightning arrester, when thunder and lightning produces electric arc; overvoltage flows into the earth by ring resistance sheet and electrode tip, thereby plays lightning-arrest and overvoltage protection effect.
