Abstract
The utility model relates to a sensor for inspecting partial discharging of a transformer, and belongs to the technical field of detection for transformers. According to the technical scheme, the sensor comprises a shell (1), an electric element and magnetic core (3), a hinge (6) and a pin buckle (2), wherein the electric element and magnetic core is arranged in the shell; the shell is divided into two parts and has a caliper type structure; one end of one part of the shell is connected with one end of the other part of the shell through the hinge; and the other ends of the two parts of the shell are connected with each other through the pin buckle. The shell has a simple and novel structure and can be opened at a large angle of 180 degrees; the grounding wire of any structure, of which the inner diameter is smaller than that of the sensor, can be clamped; the sensor can be assembled and disassembled conveniently only by buckling and unbuckling the pin buckle and can be flexibly applied to different sets of equipment; and furthermore, a large amount of assembly and disassembly time can be saved, and field partial discharging inspection test is greatly facilitated.
Description
Technical field
The utility model relates to a kind of partial discharge of transformer patrols and examines and uses sensor, belongs to transformer detection technique field.
Background technology
Current, it is varied with sensor that detection is put in office, and wherein pulses of current sensor is mainly used in the pulse current variation on the checkout equipment ground wire; But the general scope of application of this type of sensor is narrower; And installation and removal inconvenience is especially put the field of patrolling and examining in office, need frequently must change equipment to be detected and detection position; This just brings very big trouble to site test, can the labor time.
The utility model content
The purpose of the utility model provides a kind of partial discharge of transformer and patrols and examines and use sensor; Can flexible Application on distinct device; And can save a large amount of installing/dismounting times, the office at the scene of greatly facilitating puts and patrols and examines test, solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: partial discharge of transformer is patrolled and examined and is used sensor; Comprising shell, electric elements and magnetic core, hinge and pin buckles; Electric elements and magnetic core setting in the enclosure, shell is divided into two parts, is the caliper brake structure; One end of two parts shell is connected through the hinge, and the other end is through the pin buckle.
The utility model also is provided with output interface, on shell, draws, and is 45 with the pin button, and the outside is provided with the BNC guard shield; Be equipped with the nylon guard shield in the shell of caliper brake structure.
Shell adopts the caliper brake structure, and whole maximum open angle reaches 180 °.
The good effect of the utility model: the utility model shell mechanism is simply novel; Expansible mouth wide-angle reaches 180 °, can block the ground wire less than any structure of sensor internal diameter, and easy installation and removal; Only need to sell the button make-up or open to get final product; Can flexible Application on distinct device, and can save a large amount of installing/dismounting times, greatly facilitate on-the-spot office and put and patrol and examine test.
Description of drawings
Fig. 1 is the utility model embodiment synoptic diagram;
Fig. 2 is the utility model embodiment open mode synoptic diagram;
Among the figure: shell 1, pin button 2, magnetic core 3, BNC guard shield 4, nylon guard shield 5, hinge 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
Partial discharge of transformer is patrolled and examined and is used sensor, comprises shell 1, electric elements and magnetic core 3, hinge 6 and pin and buckles 2, and electric elements and magnetic core setting are in the enclosure; Shell is divided into two parts; Be the caliper brake structure, an end of two parts shell is connected through the hinge, and the other end is through the pin buckle.The utility model also is provided with output interface, on shell, draws, and is 45 with the pin button, and the outside is provided with BNC guard shield 4; Be equipped with nylon guard shield 5 in the shell of caliper brake structure.Shell adopts the caliper brake structure, and whole maximum open angle reaches 180 °.
The utility model simple in structure adopts aluminum profile extrusion to form, and in the magnetic core 3 precession shells 1, output interface is by 4 protections of BNC guard shield, and pin button 2 can tighten sensor, and hinge 6 can be opened and make the whole sensor opening angle reach 180 °.The caliper brake structural design of this uniqueness greatly facilitates on-the-spot office and puts the work of patrolling and examining.
Claims (3)
1. a partial discharge of transformer is patrolled and examined and is used sensor; It is characterized in that comprising shell (1), electric elements and magnetic core (3), hinge (6) and pin and buckle (2); Electric elements and magnetic core setting in the enclosure, shell is divided into two parts, is the caliper brake structure; One end of two parts shell is connected through the hinge, and the other end is through the pin buckle.
