Abstract
A novel wall bushing especially belongs to the wall bushing having an electronic sensor; the wall bushing comprises umbrella skirts (5), wiring terminals (6) and a flange disc (1); the wall bushing is characterized in that the flange disc is provided with a sleeve box (3); two electronic current sensors (2) are arranged in the sleeve box; two output terminals (4) are led out above the sleeve box. The novel wall bushing is convenient in mounting and measurement, safe and reliable, can save energy, and can reduce energy consumption.
Description
Technical field
The utility model relates to a kind of wall bushing, particularly belongs to a kind of wall bushing with electronic type current sensor.
Background technology
Traditional wall bushing only plays the effect of conduction current in power circuit, for the safety of instrument in the size of electric current in detection line and protection circuit, current transformer need to be installed in the line; Although there is a small amount of wall bushing to install core type instrument transformer additional at ring flange place, but because being subject to the restriction in space, measuring range is smaller, and core type instrument transformer weight is larger, generally ten to tens kilograms of left and right, be unfavorable for the installation of wall bushing, so hindered the use of the wall bushing with checkout gear.
Summary of the invention
The purpose of this utility model is to provide a kind of New type through-wall sleeve, is convenient for measuring installation, safe and reliable object to reach.
New type through-wall sleeve provided by the utility model, there is full skirt, binding post and ring flange, it is characterized in that, be provided with the cover box that a size is less than ring flange at ring flange place, in cover box, two groups of electronic type current sensors are installed, two groups of lead-out terminals are drawn in cover box top.
New type through-wall sleeve provided by the utility model, owing to having installed two groups of electronic type current sensors additional, wall bushing and transducer are combined, for the measurement in circuit and protection instrument signal is provided, avoid that current transformer is installed in the line and detected size of current, reduced operating cost; And electronic type current sensor measuring range is wide, lightweight, increase hardly the weight of wall bushing; In addition, its low feature that consumes energy has also reduced electric energy loss greatly.Therefore have install and measure conveniently, safe and reliable, energy-saving and cost-reducing good effect.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model structural representation;
Fig. 2, the utility model electronic type current sensor structural representation.
Embodiment
As shown in Figure 1, New type through-wall sleeve provided by the utility model, there is full skirt 5, binding post 6 and ring flange 1, at the ring flange place of wall bushing, the cover box 3 that one size is less than ring flange is installed, in cover box, be provided with two groups of electronic type current sensors 2, two groups of lead-out terminals 4 are drawn in cover box top.Above-mentioned electronic type current sensor, also can be substituted and be carried out work by other current sensors of realizing identical function.
As shown in Figure 2, the helix tube type air core coil of electronic type current sensor is connected with the lead-out terminal of box cover top by transducer 7.
The utility model has saved the step of current transformer being installed in the line carrying out detection line size of current; but wall bushing and electronic type current sensor are combined; and provide signal by two groups of lead-out terminals of drawing in rectangular box for the measurement in circuit and protection instrument; convenient and reliable, improve operating efficiency.
