Description
Technical field
This utility model relates to voltage measurement field, particularly to a kind of voltage sampling head.
Background technology
In middle-and-high voltage system, voltage is reduced to 100V by voltage transformer, and guides on voltage terminal, as the signal measured, protect, measure. Adopt the voltage sampling head of pin type to take voltage signal from voltage terminal at present, its stitch must being locked in voltage terminal when taking voltage signal, if there is no reserved voltage terminal, will be unable to get voltage signal.
When doing electric energy quality test, usually by an electric energy quality test instrument power taking pressure and current signal, owing in most cases reserving voltage terminal, therefore current pin type sampling head cannot be adopted, also just cannot get voltage signal.
Summary of the invention
For the problems referred to above, the purpose of this utility model is in that to provide a kind of voltage sampling head, and it also can get voltage signal when not reserved voltage terminal.
For reaching above-mentioned purpose, the proposed technical scheme of this utility model is: a kind of voltage sampling head, including main body, sleeve and screw, described main body includes a feeler lever, a connecting rod and is set in the insulation sleeve outside connecting rod, one end of described connecting rod is fixing with feeler lever to be connected, and the end of its other end is provided with screw thread; Described sleeve includes a hollow cylinder and is set in its outside insulation sleeve, and one end of described sleeve is provided with screw, is connected with the screw thread of described connecting rod, and its other end accesses for measuring head; Described screw is located at one end of feeler lever, is connected with the screw hole on voltage terminal.
Further, described feeler lever is 90 degree with the connection angle of described connecting rod.
Further, described hollow cylinder is hollow metal cylinder.
Further, described measuring head has different specifications, supports the use with described hollow cylinder.
Further, the specification of described measuring head is 4mm or 6mm.
Adopting technique scheme, voltage sampling head of the present utility model when not reserved voltage terminal, also can get voltage signal, and easy easy-to-use.
Accompanying drawing explanation
Fig. 1 is the structural representation of voltage sampling head.
Fig. 2 is the structural representation of main body in voltage sampling head.
Fig. 3 is the structural representation of voltage sampling head middle sleeve.
Wherein: 1. feeler lever; 2. connecting rod; 3. hollow cylinder; 4. insulation sleeve; 5. screw.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
As shown in Figure 1, a kind of voltage sampling head, including main body, sleeve and screw 5, main body includes feeler lever 1, connecting rod 2 and is set in the insulation sleeve 4 outside connecting rod, one end of connecting rod 2 is fixing with feeler lever 1 to be connected, connection angle can be 90 degree or other angles, and the end of the connecting rod other end is provided with screw thread.
Sleeve includes a hollow cylinder 3 and is set in its outside insulation sleeve 4, and one end of sleeve is provided with screw, is connected with the screw thread of described main body connecting rod 2, and its other end accesses for measuring head. Hollow cylinder can be hollow metal cylinder, but is not limited to this. Also can select the measuring head of different size according to required specific requirement, such as 4mm, 6mm etc., but be not limited to this, now select the sleeve hollow cylinder of dimension to match with measuring head and use.
Screw 5 is located at one end of feeler lever 1, and this screw is for vertically locking main body feeler lever in the screw hole on voltage terminal.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; in the form and details this utility model is made a variety of changes, be protection domain of the present utility model.
