Abstract
The utility model relates to a compression calibration base for the calibration and the running test of an electric energy meter, which comprises a calibration base. The current copper bar and the voltage copper bar in the compression calibration base are respectively arranged on corresponding movable bases. The movable bases are arranged on the guide rail of the calibration base and can move leftward and rightward along the guide rail. A current wiring copper block in the movable base is in elastic contact with the current copper bar or the voltage copper bar. The utility model has the advantages that: 1 the conducting current is large and the calibration safety factor is high; 2 the voltage bar can be transposed conveniently, and the calibration base is suitable for the calibration of not only 1-in 2-out meters but also 1-in 4-out meters; 3 since the current wiring copper block is connected with a temperature sensor, alarms are given automatically when the temperature of the current copper block exceeds the set value and thereby the calibration process is safe and reliable; 4 since the adjustment of the left position and the right position of the copper bar of the calibration base is realized through different copper bar spacer blocks, the adjusting speed is greatly increased and the relative position is very accurate.
Description
Technical field
The utility model relates to a kind of fast, practical electric energy meter calibrating of regulating the speed crimping calibration seat of having good luck, and belongs to electric energy meter crimping calibration seat and makes the field.
Background technology
At present, the production of electric energy meter or the examination of power office all need electric energy meter is carried out verification, has good luck.This was operated in since over half a century, it is the fastening current lead-through that realizes of copper post that relies on the calibration seat of the screw in connection terminal hole and checking table always, and general electric energy meter manufacturer needs through first revisal, this three process of resuming classes, have good luck every table, not only workload is big, and the cross recess of every screw, also can not cause damage through tense-lax repeatedly because of matching of criticizing of spiral shell, quality just can't guarantee, especially when 100 amperes of big electric currents of verification, screw need be beaten very tight, not only operation inconvenience, and inefficiency.Though have manufacturer and power office to have the crimping tester in recent years, because a variety of causes can only limit to the little reometer machine of verification below 40 amperes.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design that a kind of current lead-through ability is big, applicability is strong, make the low electric energy meter calibrating of the improvement cost crimping calibration seat of having good luck.
Design proposal: in order to realize above-mentioned purpose of design, the utility model comes the conducting electric current by the silver contact of calibration seat copper capital end and the plane of bottom, connection terminal hole or the elasticity crimping on inclined-plane.1, the top of electric current copper rod studs with the design of siller tin oxide contact, is one of technical characterictic of the present utility model.The purpose of doing like this is: the big and silver contact of silver contact current lead-through ability is difficult for oxidized, so the lead of connection terminal inputs or outputs the hole, no matter is the terminal box of wire frame folder formula, or copper rod formula terminal box, all can directly crimping calibration below 100 amperes.2, the centre wears the design of the removable electric current copper rod of removable jew banana net-fault, is two of technical characterictic of the present utility model.The purpose of doing like this is: when to size of current being table machine more than 100 amperes when carrying out verification, only need put on the removable jew banana and touch net, to increase the ducting capacity of electric current.3, being connected to temperature sensor on the electric current wiring copper billet, is three of technical characterictic of the present utility model.The purpose of doing like this is: when the copper billet temperature surpasses limit value, promptly start protector and cut off electric current.4, can the replace design of voltage copper rod is four of a technical characterictic of the present utility model.The purpose of doing like this is: by voltage copper rod transposition, can adapt to one-in-and-two-out or and advance four and go out different table machine verification demand, and needn't press with the crocodile clip power taking in addition.
Technical scheme: the electric energy meter calibrating crimping calibration seat of having good luck, it comprises the calibration seat, electric current copper rod in the described crimping calibration seat and voltage copper rod lay respectively on separately the mobile foundation, mobile foundation is positioned on the calibration seat guide rail and along the guide rail move left and right, and electric current wiring copper billet in the mobile foundation and electric current copper rod or voltage copper rod are Elastic Contact.
The utility model is compared with background technology, and the one, because of the copper rod upper end studs with the siller tin oxide contact, the ability of conducting electric current increases relatively; The 2nd, be provided with temperature sensor on the electric current copper billet, make calibration process safety coefficient height; The 3rd, the voltage rod that can replace easily is not only applicable to the verification of one-in-and-two-out table machine, and is applicable to that one advances four and goes out to show the machine verification; The 4th, the adjustment of position, the calibration seat copper rod left and right sides is to realize by different copper rod distance blocks, making regulates the speed greatly accelerate and relative position very correct; The 5th, applicability is strong, both has been applicable to the terminal box of the current copper bar structure of generally using, and also is applicable to the terminal box of the wire frame folder formula that has compressing piece; The 6th, improvement expenses is low, directly changes to get final product on checking table, and the transformation time is short, instant effect.
