CN202749805U - Decoupler - Google Patents

Abstract

The utility model relates to a decoupler. The decoupler comprises a box body, wherein an inductor, electrodes, screws and connection terminals are arranged in the box body; two ends of the inductor is connected with the two electrodes respectively; the screws and the connection terminals are fixed on the electrodes, and a line pressing device is formed by the screws, the connection terminals and the electrodes; and guide rail fasteners are mounted at the bottom of the box body. The decoupler is simple in structure and convenient to mount, and is connected in series between two surge protector lines, thereby providing functions of decoupling and voltage-dividing and increasing the inductance of the lines; and the decoupler works in cooperation with the operation and energy discharge of the surge protectors, providing maximum safety protection effects.

Description

Move back the lotus root device

Technical field

The utility model belongs to the surge protector field, relates in particular to a kind of for moving back the lotus root device between supply line's two-stage surge protector.

Background technology

When the mounting distance between the two-stage surge protector can not meet the demands (as greater than 5 meters or 10 meters), adopt generally that the power line around corresponding length solves between the two poles of the earth.The method has many defectives and inconvenience: 1, spatial limitation; 2, operation inconvenience, and increase safety failure; 3, impact is attractive in appearance etc.On these problem markets different solutions is arranged, but complicated structure, cost are high.

Summary of the invention

The purpose of this utility model is to adopt the existing the problems referred to above of wire for prior art between the two-stage surge protector, and a kind of simple in structure, easy for installation, safe lotus root device that moves back is provided.

The purpose of this utility model is achieved in that the utility model comprises box body, in described box body, be provided with inductance, electrode, screw and binding post, the two ends of inductance are connected respectively with two electrodes, described screw and binding post are fixed on the electrode, and electrode, screw and binding post three form cord grip; In the bottom of described box body the guide rail buckle is installed.

Preferably, described binding post is enclosed within the electrode lower end, and screw is screwed on the binding post by screw thread after passing the electrode upper end.Electrode upper end plays a supportive role to screw, by rotary screw binding post easy on and off in box body is slided, and electrode is to be embedded in the groove of box body to be in static stationary state.

Technique effect of the present utility model is: the utility model is simple in structure, easy for installation; be installed in series between two-stage surge protector circuit, play and move back the lotus root dividing potential drop, increase line inductance; cooperate action and the energy of two-stage surge protector to release, reach safest protection effect.

Fig. 5 is the A-A cutaway view of Fig. 4.

Fig. 6 is that the present embodiment moves back the lotus root device and is connected to schematic diagram between the two-stage surge protector.

Embodiment

Referring to Fig. 1 to Fig. 5, the present embodiment comprises box body 1, in described box body 1, be provided with an inductance 2, two electrodes 3, two screws 4 and two binding posts 5, the position of corresponding terminals 5 sons is provided with jack on box body 1, the two ends of inductance 2 are connected respectively (mode that adopts soldering to add rivet connects) with two electrodes 3, screw 4 and binding post 5 are fixed on the electrode 3, specifically binding post 5 is enclosed within electrode 3 lower ends, screw 4 is screwed on the binding post 5 by screw thread after passing electrode 3 upper ends, and electrode 3, screw 4 and binding post 5 threes form cord grip; In the bottom of box body 1 guide rail buckle 6 is installed, forms 35mm guide rail card assembling device, be used for being connected with guide rail.

Referring to Fig. 6, the present embodiment moves back lotus root device series winding and is installed between the two-stage surge protector, can play and move back the lotus root dividing potential drop, increases line inductance, cooperates action and the energy of two-stage surge protector to release, and reaches safest protection effect.

Claims (2)
