Abstract
The utility model relates to an electricity sealing cover avoiding or indicating fraudulent use of electricity for mutual inductors. The utility model is characterized in that the utility model is formed by that a seal part and a cover part are wedged; an output hole and an access hole of a wire holder of an output end of a mutual coil are arranged on the seal; the middle part of the seal is provided with bulges which are matched with half arrowhead clamping ears of the cover; a hole is formed between the two half arrowhead clamping ears, and an interlocking lever is inserted into the hole. The two half arrowhead clamping ears and the interlocking lever are integrally interlocked by the utility model through the bulges which are arranged at the middle part of the seal and matched with the half arrowhead clamping ears, so the utility model has the function of avoiding and indicating the fraudulent use of electricity at the output terminal of the mutual coil in the metering of electric power.
Description
The utility model relates to the sealing cover of the mutual inductor that uses in a kind of electric power metering device.
Electricity consumption is being carried out in the process of management through quantification, for the big power utilization network of power output, 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; This mutual inductor ringwise; the lead of tested power supply directly passes the ring heart of mutual inductor during measurement; because existing this mutual inductor; its induction output is not provided with anti-electricity-theft protective device; make people can adopt " U " shape lead to insert and connect its output the two poles of the earth carry out short circuit or 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; therefore; bring loss to national wealth; also give the anti-electricity-theft difficulty of having brought of management of power use department; thereby; press for a kind of sealing cover of design and effectively prevent this electricity filching behavior, Chinese patent database by retrieval, such sealing cover is found as yet.
The purpose of this utility model is the anti-electricity-theft sealing cover of mutual inductor secondary that uses in a kind of electric power metering device of design.
The technical solution of the utility model is achieved in that the anti-electricity-theft sealing cover of a kind of mutual inductor secondary of design, it is agreed with and is formed by envelope and cover two parts, seal up and be provided with mutual inductor output end binding post access hole and delivery outlet, the middle part of envelope is provided with the projection that matches with the half arrow shaped card ear that covers, and contract goes into to have interlocking lever in the hole that constitutes between two and half arrow shaped card ears.
The anti-electricity-theft sealing cover of aforesaid mutual inductor secondary, described envelope is arc surface with the face of covering that cover agrees with mutually.
The anti-electricity-theft sealing cover of aforesaid mutual inductor secondary, described envelope is the plane with the face of covering that cover agrees with mutually.
The anti-electricity-theft sealing cover of aforesaid mutual inductor secondary, the described groove that has to go into of sealing up for the face that the covers contract of cover.
The anti-electricity-theft sealing cover of aforesaid mutual inductor secondary, the hole of inserting for interlocking lever on the described cover is square or is rounded.
When the utility model uses, earlier big envelope is gone on the mutual inductor output end binding post, these two binding posts are screw rod and make, after penetrating the access hole, fix with nut, insert the connector lug of power instrument again, and pass from the delivery outlet of sealing up, then, to seal with cover and agree with, again interlocking lever be inserted in the hole of two and half arrow shaped card ears formation, like this, projection, two and half arrow shaped card ears and the interlocking lever three that the half arrow shaped card ear with cover that the middle part of envelope is provided with matches interlocking securely is one, and cover can not be taken off from sealing up; Have only powerful this sealing cover that damages to break a seal.
The utility model is simple in structure, and projection, two and half arrow shaped card ears and the interlocking lever three that the half arrow shaped card ear with cover that is provided with by the middle part of sealing matches interlocking securely is one, and power-steeling preventing effect is good.
Fig. 1 is a drawing in side sectional elevation of the present utility model.
Fig. 2 is the transparent stereo schematic diagram of the utility model envelope.
Fig. 3 is the schematic perspective view of the utility model cover.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
See also accompanying drawing 1, design the anti-electricity-theft sealing cover of a kind of mutual inductor secondary, it is agreed with and is formed by envelope 1 and cover 2 two parts, envelope 1 is provided with the mutual inductor output end binding post and inserts hole 3 and insert hole 4, and instrument leads delivery outlet 7 and delivery outlet 8, envelope 1 middle part be provided with the hole of covering projection 10 that 2 half arrow shaped card ear 5 and half arrow shaped card ear 6 match and protruding 11, half arrow shaped card ears 5 and 6 formations of half arrow shaped card ear in contract go into to have interlocking lever 9.
See also accompanying drawing 2, have the groove 13 of going on the envelope 1 for the face that covers 12 contracts of cover 2.
See also accompanying drawing 3, cover 2 is arc surface or is the plane with envelope 1 face that covers 12 that agrees with mutually, and the hole of inserting for interlocking lever 9 on the cover 2 is square or is rounded.
Provide a kind of mutual inductor secondary anti-electricity-theft sealing cover, it adopts engineering plastics to make, and also can adopt fiberglass to make, and envelope 1 is Transparent color, and cover 2 is black.
The dimensional parameters of given one group of anti-electricity-theft sealing cover of mutual inductor secondary, after envelope 1 is agreed with cover 2, its width is 50 millimeters, arc surface bottom is apart from 16 millimeters of bottom surfaces, and its thickness is 21 millimeters, and wherein covering 2 wall thickness is 5 millimeters, binding post access hole 4 is that 8 millimeters * 14 millimeters angle is the hole of fillet, lead delivery outlet 7 is that 5 millimeters * 8 millimeters its interior angles are the hole of fillet, and the interlocking lever patchhole is square, and it is of a size of 4 millimeters * 5 millimeters.
