Abstract
The utility model discloses a lightning protection copper aluminium wire clamp comprising a porcelain sleeve, a supporting plate, an arc-striking pole, an arc-striking rod, a copper aluminium wire clamp and a wire clamp insulating cover and so on. The arc rod is screwed and fastened on the copper aluminium wire clamp, and connected to an overhead line to form a high potential. The arc pole is screwed and fastened on the supporting plate which is screwed and fastened through a fastening bolt of the porcelain sleeve. The arc pole and the arc rod are in a face-to-face relationship up and down, to form an air gap. When the lightning protection copper aluminium wire clamp is stroken by thunder, a short circuit channel is formed to cause sparkover discharge. Continuous power frequency arcs are burnt herein, to protect a transformer from being burnt, protect a wire from being burnt out, and also protect the porcelain sleeve from being burnt. The arc rod and the copper aluminium wire clamp are covered by the insulating cover for safety. The device is characterized by compact structure and convenient installation. When a lighting arrester is in a state of ineffectiveness or burning loss, the device can perform secondary protection on the transformer.
Description
Technical field:
The utility model belongs to the power equipment that electric power delivery transformer is used.
A kind of electric power delivery transformer prevent from being struck by lightning device of scaling loss.
Background technology:
Lightning discharge is a kind of powerful phenomenon of outburst naturally, is difficult to prevent, and for hiding and limit its destructiveness, should take necessary Lighting Protection Measures, otherwise impact is normal for electricity consumption, and economic loss is very large; Distribution transformer phenomenon improper due to lightning protection measures and scaling loss is of common occurrence; Theory analysis and actual tests show: the main cause of distribution transforming damage to crops caused by thunder accident---the overvoltage of " positive inverse transformation " while suffering from mines due to distribution system causes, the superpotential damage accident of inverse transformation is particularly serious.
At present, Lighting Protection Measures is mainly to establish lightning rod, lightning conducter, lightning arrester and earthing device.
Summary of the invention:
The utility model device, according to the theory analysis of distribution transforming damage to crops caused by thunder accident and actual tests and the realistic problem that runs in consumers' opinions and electric network reconstruction in recent years repeatedly, and develop a kind of lightning protection device---high voltage side of transformer copper aluminum wire clamp one place installs starting rod additional, starting rod has resistance to thick silicon rubber insulating sleeve to cover, arc ignition bar is equipped with in the bottom of high-pressure side porcelain bushing, arc ignition bar is spirally connected and is fixed in supporting bracket, utilize the set bolt of the porcelain bushing fixed support plate that is spirally connected, starting rod and arc ignition bar in opposite directions and to form discharge channel, this apparatus structure is simply compact, easy for installation.
The technical solution of the utility model is:
This device is by porcelain bushing 2, presser feet 3, and supporting bracket 4, arc ignition bar 5, starting rod 6, copper aluminum wire clamp 7, wire clamp insulating cover 8 assembles.
Presser feet 3 is conventionally punching press iron pieces of application, and appearance hot galvanizing, carries sleeve pipe fastening force with it.
Supporting bracket 4 is punching press iron pieces, appearance hot galvanizing, and its slotted eye 4.1 2 places are fastened on respectively on the bolt of two pieces of presser feets 3, its outside aperture dress arc ignition bar 5.
Starting rod 6 is iron pieces, and one end is spherical shape, and the other end is that thread segment 6.1 is spirally connected and is fastened on the screw 7.2 of copper aluminum wire clamp 7, and starting rod 6 is high potential, exposes the insulating case parcel that part manufactured by silicon rubber and covers.
Copper aluminum wire clamp 7 is screwed onto on the top thread segment 2.1 of porcelain bushing 2, located by two pieces of bolted, and screw 7.2 places of bottom one side fastening the starting rod that is spirally connected, starting rod 6 and arc ignition bar 5 in opposite directions and right, form air gap (discharge channel).
Wire clamp insulating cover 8 is made up of weather-proof plastics, and charged copper aluminum wire clamp 7 is covered, and makes it safer.
Accompanying drawing explanation:
Fig. 1 is the utility model structure chart.
Fig. 2 is porcelain bushing.
Fig. 3 is presser feet.
Fig. 4 is supporting bracket.
Fig. 5 is arc ignition bar.
Fig. 6 is starting rod.
Fig. 7 is copper aluminum wire clamp.
Fig. 8 is wire clamp insulating cover.
Wherein: 2-is porcelain bushing, 3-is presser feet, and 4-is supporting bracket, and 5-is arc ignition bar, and 6-is starting rod, and 7-is copper aluminum wire clamp, and 8-is wire clamp insulating cover; 2.1-is bolt, and 4.1-is slotted eye, and 6.1-is screw thread, and 6.2-is electric discharge window, and 7.1-is copper nut, and 7.2-is screw.
Embodiment
Two slotted eyes 4.1 of supporting bracket insert respectively bolt on presser feet 3 fastening, and supporting bracket is towards the outside of transformer, and arc ignition bar 5 inserts the circular hole of supporting bracket, by upper and lower fastening nuts; The thread segment 6.1 of starting rod is screwed onto on the screw 7.2 of copper aluminum wire clamp, and the bulb electric discharge window 6.2 of starting rod down; The copper nut 7.1 of copper aluminum wire clamp is spirally connected with the bolt 2.1 of porcelain bushing, after starting rod 6 aligns with arc ignition bar 5 below, tightens two pieces of fastening bolt location on copper aluminum wire clamp; This device is for the high-pressure side of transformer, therefore starting rod 6 has just become high potential, arc ignition bar 5 is electronegative potential; Starting rod 6 and arc ignition bar 5 in opposite directions and right, form air gap; When thunderbolt occurs, between starting rod hemispherical ends 6 and arc ignition bar hemispherical ends 5, form short-channel, cause flashover electric discharge; the power frequency arc continuing burns herein; exempt from scaling loss with protection transformer, also can guardwire exempt from and blow, can also protect porcelain bushing to exempt from scaling loss.Arc rod 6 appearances are covered by insulating case, and copper aluminum wire clamp 7 has wire clamp insulating cover to cover, to improve fail safe.When lightning arrester on bar is malfunctioning or scaling loss, this device can also have second protection transformer action.
