Description
Technical field
The utility model relates to instrument transformer technical field, particularly relates to a kind of compression type Anti-frandulent use of electricity mutual inductor mounting structure.
Background technology
At present, the electricity distributing and metering device used is many to be made up of metering electric energy meter and instrument transformer.As shown in Figure 1, the instrument transformer 1 power taking when mounted pressure screw rod 3 of punching structure is too little with conducting rod 2 contact area, the connected mode of this conducting rod 2 and to get voltage system all not firm, easily transformer low voltage side terminal is burnt by heating, causes the damage of transformer.
Utility model content
Technical problem to be solved in the utility model is: in order to overcome deficiency of the prior art, the utility model provides a kind of compression type Anti-frandulent use of electricity mutual inductor mounting structure, this structure increases the contact area of power taking pressure screw rod and conducting rod, and connect reliable, security performance is good.
The utility model solves the technical scheme that its technical problem will adopt: a kind of compression type Anti-frandulent use of electricity mutual inductor mounting structure, comprise instrument transformer, conducting rod and power taking pressure screw rod, described instrument transformer is fixed on described conducting rod, described instrument transformer is provided with the brass thread hole running through instrument transformer, described power taking pressure screw rod is connected with described conducting rod by described brass thread hole, the end that described power taking pressure screw rod is connected with described conducting rod is provided with power taking briquetting, the shell wall that described instrument transformer is relative with described conducting rod is provided with the groove holding described power taking briquetting, described power taking briquetting has the curvature identical with conducting rod, the side of described power taking briquetting projection is provided with the internal thread hole of pressing screw rod to match with described power taking.Adopt arc power taking briquetting to increase the contact area of power taking pressure screw rod and conducting rod, make connection more firm.Power taking briquetting adopts the good metal material of electric conductivity to make, and it is yielding to have certain hardness.
Further, the side of described power taking briquetting projection is provided with boss, and described boss is provided with the internal thread hole of pressing screw rod to match with described power taking.The contact area that boss increases power taking pressure screw rod and power taking briquetting is further set, makes connection more firm.
The beneficial effects of the utility model are: the utility model provides a kind of compression type Anti-frandulent use of electricity mutual inductor mounting structure, adopt the arcuate structure of power taking briquetting, increase the contact area of power taking pressure screw rod and conducting rod, connect reliable, security performance is good, significantly reduces the probability causing transformer damage because step-down side is overheated.

Embodiment
By reference to the accompanying drawings the utility model is described in detail now.This figure is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.
As in Figure 2-4, a kind of compression type Anti-frandulent use of electricity mutual inductor mounting structure of the present utility model, comprise instrument transformer 1, conducting rod 2 and power taking pressure screw rod 3, instrument transformer 1 is fixed on conducting rod 2, instrument transformer 1 is provided with the brass thread hole running through instrument transformer 1, power taking pressure screw rod 3 is connected with conducting rod 2 by brass thread hole, the end that power taking pressure screw rod 3 is connected with conducting rod 2 is provided with power taking briquetting 4, the shell wall that instrument transformer 1 is relative with conducting rod 2 is provided with the groove holding described power taking briquetting 4, power taking briquetting 4 has the curvature identical with conducting rod 1, the side of power taking briquetting 4 projection is provided with the internal thread hole 5 of pressing screw rod 3 to match with power taking.Adopt arc power taking briquetting 4 to increase power taking pressure screw rod 3 and the contact area of conducting rod 2, make connection more firm.The metal material that power taking briquetting 4 adopts electric conductivity good is made, and it is yielding to have certain hardness.
The side of power taking briquetting 4 projection is provided with boss 6, and boss 6 is provided with the internal thread hole 5 of pressing screw rod 3 to match with power taking.Boss 6 is set and increases power taking pressure screw rod 3 and the contact area of power taking briquetting 4 further, make connection more solid and reliable.
During installation, power taking pressure screw rod 3 is by screwing in the internal thread hole 5 on power taking briquetting 4 behind brass thread hole, when power taking pressure screw rod 3 is in the process screwed, promote power taking briquetting 4 to compress to conducting rod 2 direction, because power taking briquetting 4 has identical curvature with conducting rod 2, therefore when pressure is enough large, both contact-making surfaces can be good at coordinating, thus increase the contact area of power taking pressure screw rod 3 and conducting rod 2.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff not departing from scope of the present utility model, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
