Embodiment 1

[0019] Embodiment 1. A wireless measuring instrument for the insertion depth of switchgear contacts, including a casing 11, which is provided with a control box 10, a power cord 12, a display screen 1, a keyboard 2 and a detector storage box 7, and the casing 11 11 is provided with a hole slot, and the antenna seat 3 hinged with the casing 11 is arranged in the hole slot, and the antenna I4 is installed on the antenna seat 3; the detector storage box 7 is provided with a handle 8, and the detector storage box 7 is installed There is a detector; the casing 11 is provided with a magnet I13, the detector storage box 7 is provided with a buckle bar 9, and the buckle bar 9 is provided with a magnet II14; the detector includes an upper detector 5 and a lower detector 6, the front ends of the upper detector 5 and the lower detector 6 are respectively provided with a detection disc 15, the bottom of the upper detector 5 and the lower detector 6 are provided with a clamp block 16, and t...

Embodiment 2

[0020] Embodiment 2. A wireless measuring instrument for the insertion depth of switchgear contacts. The clamping blocks 16 are respectively hinged to the bottom of the upper detector 5 and the lower detector 6. One end of the spring 17 is fixed on the clamping block 16, and the other end is fixed on the On the detector, others are the same as in Example 1.

[0021] During use, the upper detector 5 and the lower detector 6 respectively clamp the root position of the moving contact of the switch cabinet through the clamp block 16, and the protruding length of the arc-shaped optical sensor 20 on the detection disc 15 is flush with the end of the moving contact. Open the antenna base 3 and turn the antenna I4 out of the casing 11. When the switch cabinet is pushed, the arc-shaped light sensor 20 installed on the detection disk 15 at the front end of the upper detector 5 and the lower detector 6 on the moving contact will be blocked by the static contact, and the laser emission po...

Abstract

The invention discloses a switch cabinet contact insertion depth wireless measuring instrument and belongs to the field of power detection equipment. Through the wireless measuring instrument, the problem that a switch cabinet contact insertion depth wireless measuring instrument, which is simple in structure, visual in measurement data display and capable of improving the efficiency of switch cabinet contact insertion depth measurement, is lacking in the prior art is solved. The wireless measuring instrument mainly comprises a shell, wherein a control box, a power line, a display screen, a keyboard and a detector storage box are arranged on the shell, an antenna pedestal is arranged on the shell, and an antenna I is installed on the antenna pedestal; a handle is arranged on the detector storage box, and a detector is installed in the detector storage box; the detector comprises an upper detector part and a lower detector part, wherein a detection disk and a clamping block are arranged on the upper detector part, a detection disk and a clamping block are arranged on the lower detector part, and the upper detector part and the lower detector part are connected through a wire; an antenna II is arranged on the upper detector part; an arc-shaped optical sensor, a laser transmitting port and a laser receiving port are arranged on the detection disk of the upper detector part; and an arc-shaped optical sensor is arranged on the detection disk of the lower detector part. The wireless measuring instrument is mainly used for switch cabinet moving contact insertion depth detection.

Description

technical field [0001] The invention relates to a power detection device, in particular to a wireless measuring instrument for the insertion depth of a switch cabinet contact. Background technique [0002] The contact process of the moving and static contacts of the switch cabinet cannot be directly visualized, and this process is precisely the key to whether the switch can operate normally. The surface of the contact is constantly oxidized, which accelerates the increase of the contact resistance. This cycle will eventually lead to arcing, and even explosions and fires, causing extensive losses and seriously affecting the reliability indicators and high-quality service of the equipment. The insertion depth of the moving contact is generally between 15-25mm according to the manufacturer's standard. The traditional inspection method is mainly by applying Vaseline and observing the imprint of the static contact. It can only qualitatively indicate that the movable and static c...
