Description
Technical field
The utility model relates to the anti-electricity-theft sealing cover of the secondary that uses in a kind of electric power metering device anti-electricity-theft sealing cover, especially Current Transformer Secondary.
Prior art
In the process that electricity consumption is managed, for the big power utilization network of output power, because the value of its voltage or electric current is bigger, so often adopt mutual inductor tested voltage or electric current to be carried out the secondary measurement of output stage when measuring, utilize the fixedly induction ratio of mutual inductor again, calculate the power consumption of power utilization network primary voltage or electric current; At present, mutual inductor can be divided into punching mutual inductor or Wound-rotor type mutual inductor in technological design, if the induction output terminal to it is not provided with anti-electricity-theft device, then electricity filching person can utilize " U " shape lead to connect its output terminal two ends, perhaps and connect a part flow arrangement and shunt, the technical parameter that records like this is with serious distortion, the power consumption that calculates will be significantly smaller than actual power consumption, in order to address this problem, the utility model applicant studies the punching mutual inductor, invented at the anti-electricity-theft sealing cover of the secondary of punching mutual inductor, i.e. " the anti-electricity-theft sealing cover of mutual inductor secondary ", the patent No. is ZL002297121; But, this sealing cover is only applicable to the situation of mutual inductor secondary output end binding post when being positioned at mutual inductor side and mutual inductor nameplate and being in diverse location, it is unfavorable for the mutual inductor nameplate is protected, thereby easily bring out by damaging nameplate, reduce the situation generation that mutual inductor ratio reaches the stealing purpose, at this situation, mutual inductor manufacturer has designed the punching mutual inductor of another kind of form, on the same side that its secondary output end binding post and nameplate are in mutual inductor, on the mutual inductor that connects nameplate, have the fixedly little screw of nameplate, for preventing stealing, the deviser also seals nameplate and mutual inductor secondary output end binding post by the connection of nut bar together with sealing cover, adds lead sealing on the cap head of nut bar, like this, could contact nameplate and stealing but have only the lead sealing of destruction to take off sealing cover, thereby stay the evidence of stealing; But because lead sealing easily forges, so, often exist electricity filching person to destroy lead sealing after, the behavior of implementing stealing is difficult for being found, and therefore, must improve this sealing cover, to strengthen its thief-proof function; Also there is same situation in the Wound-rotor type mutual inductor.
Technical scheme
The purpose of this utility model provides a kind of with after the mutual inductor body cooperates, change the mutual inductor secondary and bring out the extension line direction, anti-" U " shape card stealing utilizes the screw on mutual inductor body and the nameplate, replace existing lead sealing, make it strengthen the anti-electricity-theft sealing cover of mutual inductor secondary of anti-stealing electricity function.
The technical solution of the utility model is achieved in that
Provide a kind of mutual inductor secondary anti-electricity-theft sealing cover, it is characterized in that it is made up of face shield and plastic packaging, have the plastic packaging hole that cooperates with plastic sealing base on the face shield, plastic sealing base places in the plastic packaging hole, pass plastic sealing base bottom aperture, plastic packaging hole bottom aperture and be connected with screw on the mutual inductor body and fix by screw rod, plastic packaging is docked with plastic sealing base by plastic packaging-cover to be formed.
The anti-electricity-theft sealing cover of aforesaid a kind of punching mutual inductor secondary, it is characterized in that described face shield is provided with a plastic packaging hole, be symmetrical arranged respectively on the two side of face shield be useful on the mutual inductor secondary terminals advance totally 4 of wire holes, adjacent two sidewalls are rectangle, and its height is less than the described height that advances wire hole.
The anti-electricity-theft sealing cover of aforesaid a kind of punching mutual inductor secondary is characterized in that being symmetrically arranged with on the described face shield two plastic packaging holes, and the face shield bottom is arch, is symmetrically arranged with into wire hole on the two side of face shield.
The anti-electricity-theft sealing cover of aforesaid a kind of Wound-rotor type mutual inductor secondary, it is characterized in that described face shield is provided with a plastic packaging hole, face shield and mutual inductor surface of contact by one side be arch, adjacent one side linearly shape or shaped form constitute, be in same face portion with the side in plastic packaging hole and have the turnover wire casing.
The anti-electricity-theft sealing cover of aforesaid a kind of Wound-rotor type mutual inductor secondary is characterized in that described face shield is provided with two plastic packaging holes, and face shield is connected across on the mutual inductor two side walls, and two section tops respectively have a trough about it.
Through more than the anti-electricity-theft sealing cover of mutual inductor secondary after being provided with, during use, the secondary terminals outlet is connected on the secondary connection post of mutual inductor, cabling mode is around the mutual inductor inwall, after making it out binding post, change direction of routing and along advancing wire hole or the trough position lays out, load onto sealing cover, nameplate is covered, plastic sealing base is packed in the plastic packaging hole, pass plastic sealing base bottom aperture, plastic packaging hole bottom aperture with screw rod again and is connected with screw on the mutual inductor body and fixes, post the holographic laser anti-counterfeiting transparent plastic packaging-cover of target of encoding with the back side and be enclosed on the plastic sealing base.
The utility model is owing to the mode that has adopted the outlet of control mutual inductor secondary terminals, and line outlet is bigger apart from secondary terminals binding post distance, and outlet direction is also different, has therefore stopped electricity filching person " U " shape card stealing; And because the anti-electricity-theft sealing cover of various mutual inductor secondaries has all adopted holographic laser anti-counterfeiting coding plastic packaging, therefore the lead sealing that replaced tradition, falls behind, has stopped to change the envelope reduction again and the behavior of stealing after the breaking-up lead sealing; Because the coding of the holographic laser anti-counterfeiting on the transparent plastic packaging-cover and user's unique corresponding relation also are convenient to electric administrative department and are realized computer management.
