Abstract
The utility model discloses a 10kV outdoor dry type combined type mutual inductor which consists of two current mutual inductors (8), two voltage mutual inductors (7) and insulation protection bodies (1). The insulation protection bodies (1) can be cast into a profile modeling structure for outdoor with epoxide resin through vacuum. The installation occupying space of the utility model is small, the function intensive degree is high, and the utility model is welcomed by the power metering department.
Description
The utility model belongs to the middle pressure converting equipment in the electric power system, is the crucial signal transmission equipment of electric power system electric energy metrical and relaying protection.
At present, plain edition oil immersed type instrument transformer is suitable for using indoor and outdoor, and its insulation system mostly is insulating paper and transformer oil compound inslation, and volume is big and heavy, and inflammable, contaminated environment can not be directly installed on load center.Chinese patent ZL 98251827.7 discloses a kind of " outdoor type dry-type voltage inductor ", and this voltage transformer adopts the insulating protector of the outdoor type epoxy resin of moulding by casting as voltage transformer, and its bushing surface casting becomes full skirt corrugated; Chinese patent ZL 98249687.7 discloses a kind of " Outdoor Dry-Type Current Transformer ", and this current transformer also adopts the insulating protector of the outdoor type epoxy resin of moulding by casting as voltage transformer, and it is corrugated that its outer surface pours into full skirt.Special-purpose closed terminal box is installed at the secondary leading-out terminal place of these two kinds of instrument transformers, miniaturization, no oiling, totally-enclosed, non-maintaining, unattended operation have been reached, and can expose the purpose of installation in the open, but these two kinds of instrument transformers only can insert the single-phase electric wire of 10kV, can only realize the purpose of single metering current or voltage.If insert the three-phase wire of 10kV, then need to install three voltage transformers and three current transformers, so both increased the cost of equipment, take up room again.
The purpose of this utility model is to provide a kind of and can uses out of doors, can insert the combined instrument transformer of three-phase wire and while metered voltage and electric current again simultaneously.
In order to achieve the above object, the current transformer of two 10kV and the voltage transformer of two 10kV are equipped with in inside of the present utility model, and current transformer places two, the inner left and right sides of the present utility model, and voltage transformer places both sides before and after the middle part of the present utility model.The utility model adopts outdoor type epoxy resin to pour into the insulating protector of combined instrument transformer under vacuum environment; the first half of insulating protector has 3-5 layer full skirt; crown center partly is the primary connection post of voltage transformer; 5-7 layer full skirt arranged; two ends, the left and right sides, top are the primary connection post of current transformer, and 5-7 layer full skirt arranged.
Because the utility model adopts outdoor type epoxy resin to replace plain edition epoxy resin to make insulating protective layer; make combined instrument transformer have the ability of ultraviolet radiation resisting, weathering resistance erosion; no oiling, fire-retardant, antipollution purpose have been realized, long-time running under can be the out of doors full weather conditions.Because the current transformer of two 10kV and the voltage transformer of two 10kV are equipped with in inside of the present utility model, its profile pours into imitated structure according to the planform of instrument transformer internal-internal, thereby the electric current that can use two-phase electric wire in the metering of combined instrument transformer A, B, the C three-phase wire and this two-phase electric wire are separately to another voltage of electric wire mutually, compare with the voltage transformer of two 10kV with the current transformer of two 10kV, saved the consumption of outdoor type epoxy resin, dwindle volume, reduced production cost.Because the utility model is installed little, the function intensification degree height that takes up room, and is subjected to the welcome of electric-power metering department.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is an end view of the present utility model.
As Fig. 1, Fig. 2 and shown in Figure 3, two current transformers 8 place two, the left and right sides of the utility model inside, and two voltage transformers 7 place both sides before and after the middle part of the present utility model.Adopt outdoor type epoxy resin under vacuum environment, to pour into the insulating protector 1 of combined instrument transformer; in order to increase creepage distance; the first half of insulating protector 1 has 4 layers of full skirt; crown center partly is the primary connection post 2 of voltage transformer; 4 layers of full skirt are also arranged; two ends, the left and right sides, top are the primary connection post 3 of current transformer, and 6 layers of full skirt are arranged.There is the secondary connection box 6 of direct moulding by casting at the lower front side middle part of insulating protector 1, with the gland of nameplate double as secondary connection box 6, between the two with the rubber cushion sealing, to reach the effect of good seal.Bolt on the nameplate has lead seal hole, can prevent that the user from passing through the instrument transformer stealing.The bottom of insulating protector 1 is useful on the channel-section steel support 5 of installation, and 4 lifting bolts 4 are arranged on the channel-section steel support 5, can lift easily.
