Abstract
The utility model provides an outdoor metering box used for metering, which is formed by pouring a primary coil, a secondary coil, a primary terminal, a secondary terminal and an iron core with epoxy resin; the primary terminal is provided with an antitheft electronic cover; a lead seal component is arranged outside the antitheft electronic cover and the primary terminal; and the secondary terminal is an armored cable led out of the inside of a mutual inductor directly. Since the primary terminal is provided with the antitheft electronic cover and the secondary terminal is the armored cable led out of the inside of the mutual inductor directly, intermediate connection is eliminated and the anti-electricity steal capability of the metering box is improved. Meanwhile, the outdoor metering box has the advantages of high insulation intensity, rainwater and moisture prevention properties, good anti-pollution property, etc.
Description
Technical field
The utility model relates to a kind of instrument transformer, refers more particularly to a kind of outdoor metering batch meter.
Background technology:
Open air metering commonly used at present adopts epoxy resin to water structure with batch meter, and primary winding, secondary coil and iron core are formed black box with epoxide-resin glue, and the outside is provided with the full skirt of several layers poured with epoxy resin.The primary winding lead-in wire is drawn with copper bar and copper bar exposes, and the secondary terminal is a binding post, is located in the terminal box, and terminal box is furnished with the sealing lid of tape punching.This structure covers two binding posts with lid, but, there is the gap between the perforation of lid and terminal box and inlet wire and terminal box, when raining, rainwater is easy to flow in the terminal box along the gap between the perforation of lid and terminal box and inlet wire and terminal box, and binding post is corroded, use inconvenient, waterproof, anti-tidal range, the easy oxidation of wiring place influences useful life of instrument transformer.In addition, protection, antitheft electric ability.Because one time copper bar is exposed outside, easily by lawless person's stealing.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, and provides a kind of rainwater simple in structure, reasonable in design, anti-, humidity resistance good, thief-proof good electrical property open air metering batch meter.
The technical scheme that technical problem adopted that solves is:
1, outdoor metering comprises primary winding, secondary coil, primary connection end, secondary connection end and iron core with batch meter, above-mentioned primary winding, secondary coil, primary connection end, secondary connection end and iron core are annotated with epoxide-resin glue and are formed, the outside is provided with the full skirt of several layers poured with epoxy resin, it is characterized in that primary connection end external insulation layer is provided with external screw thread, be provided with anti-electricity-theft cover at the primary connection end, anti-electricity-theft cover is the sleeve pipe that is provided with internal thread, and anti-electricity-theft cover is connected with primary connection end external insulation layer spiral shell.During use, connecting line is connected with a leading-out terminal by anti-electricity-theft cover, and anti-electricity-theft cover has guaranteed that the primary connection end can not expose.
When 2, specifically implementing, the anti-electricity-theft lead seal hole that is covered with, the outside of anti-electricity-theft cover and primary connection end is provided with the lead sealing assembly.By anti-electricity-theft cover and lead sealing assembly, to improve anti-electricity-theft performance.
When 3, specifically implementing, anti-electricity-theft cover is to adopt the poured with epoxy resin moulding.
When 4, specifically implementing, the secondary connection end is that armoured cable is directly drawn from instrument transformer inside.This mechanism has changed original binding post connected mode, the phenomenon that does not exist binding post to be corroded, and protection level obviously improves.
The beneficial effects of the utility model are: owing to adopt the primary connection end to adopt anti-electricity-theft cover, the secondary terminal is directly to be drawn internally by armoured cable, thereby connect the antitheft electric energy power that has improved batch meter in the middle of reducing, have the dielectric strength height simultaneously, prevent advantages such as rainwater, humidity resistance and antifouling property are good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the left view of the utility model embodiment.
Among the figure 1, primary connection end 2, anti-electricity-theft cover 3, armoured cable 4, lead sealing assembly 5, full skirt
Embodiment:
As shown in Figure 1, 2, the outdoor metering of present embodiment is annotated with epoxide-resin glue by primary winding, secondary coil, primary connection end 1, secondary connection end and iron core with batch meter and is formed, the outside is provided with the full skirt 5 of several layers poured with epoxy resin, and the secondary connection end is that armoured cable 3 is directly drawn from instrument transformer inside; Primary connection end 1 external insulation layer is provided with external screw thread, is provided with anti-electricity-theft cover 2 at a leading-out terminal, and anti-electricity-theft cover 2 is to adopt the poured with epoxy resin moulding, and anti-electricity-theft cover 2 is for being provided with the sleeve pipe of internal thread, and anti-electricity-theft cover 2 is connected with primary connection end 1 external insulation layer spiral shell; Anti-electricity-theft cover 2 is provided with lead seal hole, and the outside of anti-electricity-theft cover 2 and primary connection end is provided with lead sealing assembly 4, by anti-electricity-theft cover 2 and lead sealing assembly 4, to improve anti-electricity-theft performance.The epoxy resin surface of primary connection end 1 is provided with P1, P2 sign.
