Abstract
The utility model discloses a telescopic tong-type ammeter. The telescopic tong-type ammeter includes a shell, and a feed-through current transformer and a data display instrument arranged in the shell. An iron core of the current transformer is a jaw. The jaw is disposed on the upper part of the shell. A telescopic rod is connected to the lower part of the shell fixedly. The telescopic rod is composed of more than two insulating tubes and the neighboring two insulating tube are fixed together through threaded connection. The data display instrument is fixed on a tail end of the telescopic rod. The data display instrument is connected with the current transformer through a lead in the telescopic rod. A pull ring is arranged on the lower part of the shell. The pull ring is connected with the jaw through a connection rope and a spring arranged in the shell. The telescopic tong-type ammeter provided by the utility model is simple in structure and convenient to operate. The measurement height can be increased, the remote operation of the telescopic tong-type ammeter by testers is realized, so that contacting a current carrying conductor in a close ranged is avoided. Therefore, the telescopic tong-type ammeter is safe and very convenient for using.
Description
Technical field
The utility model relates to a kind of current measuring device, especially relates to a kind of Telescopic clip-on ammeter.
Background technology
When usually measuring electric current with the common current table, the reometer access could be measured after circuitry cuts need to being shut down, this is pretty troublesome, and the motor of normal operation does not allow to do so sometimes.Use clamp on amperemeter just to seem more convenient, can measure electric current in the situation that do not cut off circuit.Clamp on amperemeter comprises housing, is arranged at straight-through current transformer and the data display instrument of enclosure interior, a part of iron core of current transformer is made pincerlike active open, it is jaw, jaw is positioned at the top of housing, the operating switch of jaw folding is placed in the housing side, and the data display instrument is fixed on the bottom of housing.At present, clamp on amperemeter with its be convenient for carrying, characteristics such as simple to operate and be widely adopted in work about electric power on-the-spot.Higher due to the branched line position, need tester's hand-held clamp on amperemeter of ascending a height to measure, use very inconveniently, easily damage clamp on amperemeter, testing efficiency is low, and with the live part close contact, very dangerous.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of simple in structure, easy to use, Telescopic clip-on ammeter that testing efficiency is high.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Telescopic clip-on ammeter, it comprises housing, is arranged at the straight-through current transformer of enclosure interior, the data display instrument, and the iron core of current transformer is jaw, and jaw is positioned at the top of housing; Lower housing portion is fixedly connected with an expansion link, above and adjacent two joints are threaded connection fixing insulation tube and form expansion link by two joints, be fixed with the data display instrument on the end insulation tube of expansion link, the data display instrument is connected with current transformer by the wire of expansion link inside; Lower housing portion is provided with a draw ring, and the connection cord that draw ring arranges by enclosure interior, spring are connected with jaw.
Owing to adopting technical scheme as above, the utlity model has following superiority:
This Telescopic clip-on ammeter, it is simple in structure, easy to operate, by in lower housing portion, expansion link being set, improve measuring height, not only can measure substation transformer secondary outgoing line side phase current, can also measure low-voltage platform area branched line phase current, and realize tester's remote-controlled operation clamp on amperemeter, avoid the close contact current carrying conductor, safer, very easy to use; The data display instrument is arranged on the end of expansion link, facilitates reading and record of data.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: the 1-jaw; The 2-reometer; The 3-expansion link; 4-data display instrument; The 5-draw ring; The 6-housing; The 7-current carrying conductor.
Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is described in further detail below by embodiment.
As shown in Figure 1, this Telescopic clip-on ammeter, it comprises housing, is arranged at the straight-through current transformer of enclosure interior, the data display instrument, and the iron core of current transformer is jaw 1, and jaw is positioned at the top of housing 6; Lower housing portion is fixedly connected with an expansion link 3, above and adjacent two joints are threaded connection fixing insulation tube and form expansion link by two joints, be fixed with data display instrument 4 on the end insulation tube of expansion link, the data display instrument is connected with current transformer by the wire of expansion link inside; Housing 6 bottoms are provided with a draw ring 5, are provided with connection cord and the spring that is connected in enclosure interior, and draw ring 5 is connected with jaw 1 by inner connection cord, the spring that arranges of housing 6.
when using the electric current of the utility model Telescopic clip-on ammeter test low-voltage platform area branched line current carrying conductor, expansion link 3 is opened, jaw 1 is aimed at current carrying conductor 7, pull draw ring 5, jaw is opened, the tested wire that dams is placed in jaw, the wire that dams becomes the first siding ring of current transformer, unclamp draw ring, close jaw, just there is alternating flux to pass through in the iron core of current transformer, produce induction current in the Secondary Winding of mutual inductor, reometer 2 is connected to Secondary Winding two ends, the indicated current value of its pointer is directly proportional to the working current that clamps the wire that dams that enters, just reading the numerical value of electric current on the wire that dams this moment on data display instrument 4, and record.After test is completed, pull draw ring, jaw is opened, and makes the wire that dams break away from clamp on amperemeter.
Claims (1)
1. Telescopic clip-on ammeter comprises housing, is arranged at straight-through current transformer, the data display instrument of enclosure interior, and the iron core of current transformer is jaw, and jaw is positioned at the top of housing; It is characterized in that: its housing (6) bottom is fixedly connected with an expansion link (3), above and adjacent two joints are threaded connection fixing insulation tube and form expansion link by two joints, be fixed with data display instrument (4) on the end insulation tube of expansion link, the data display instrument is connected with current transformer by the wire of expansion link inside; Lower housing portion is provided with a draw ring (5), and the connection cord that draw ring arranges by enclosure interior, spring are connected with jaw (1).
