Embodiment 1

[0030] like figure 1 and figure 2 As shown, an arc sensor test light source generator and a test method thereof provided in this embodiment include a fixed substrate 1, a front panel 2 fixed on one side of the fixed substrate 1, and a closed casing 3 fixed on the fixed substrate 1, An arc sensor adapter 4 is fixed on one side of the front panel 2, an angle adjustment motor 7 is installed under the fixed base plate 1, the rotation shaft of the angle adjustment motor 7 passes through the fixed base plate 1, and a main control unit is installed above the fixed base plate 1 10, the cantilever 6 and the angle sensor 8 located below the cantilever 6, the cantilever 6 is fixed on the rotating shaft of the angle adjustment motor 7, the light source 5 and the light stabilizing unit 9 are fixed on the cantilever 6, the light stabilizing unit 9 includes an optical feedback circuit 91 and a The light source control circuit 92 connected to the optical feedback circuit 91, the main contro...

Embodiment 2

[0043] The main difference between this embodiment 2 and embodiment 1 is as follows:

[0044] In this example, if image 3 As shown, as a preferred embodiment of the test method for inventing an arc sensor to test the light source, the light source 5 includes two light sources of visible light and ultraviolet light, and there are two cantilevers 6. The two cantilevers are distributed orthogonally and the intersection point is located at On the axis of the angle-adjusting motor 7, the optical axes of the two light sources are orthogonal and are located in the same plane as the axis of the arc sensor adapter 4. The light source distribution can meet the test requirements of the two light sources at the same time, and each light source can be It can be adjusted within the range of 0 to 90 degrees.

[0045] In this example as image 3 As shown, during specific work, two light sources are selected as the test light sources, and the CPU 101 of the main control unit 10 receives the...

Abstract

The invention discloses an arc light sensor testing light source generation device and a testing method thereof,and belongs to the technical field of arc light detection and protection. The arc lightsensor testing light source generation device comprises a fixed base plate,a front panel fixed to one side of the fixed base plate and a sealed shell fixed to the fixed base plate; an arc light sensoradapter is fixed to one side of the front panel,an angle modulation motor is arranged below the fixed base plate,a rotary shaft of the angle modulation motor penetrates through the fixed base plate,and a main control unit,suspending arms and an angle sensor which is located below the suspending arms are arranged above the fixed base plate; the suspending arms are fixed to the rotary shaft of theangle modulation motor,light sources and a light stabilizing unit are fixed to the suspending arms,and the light stabilizing unit comprises a light feedback circuit and a light source control circuitconnected with the light feedback circuit. By means of the arc light sensor testing light source generation device and the testing method thereof,the problem that manual operation has large errors issolved by using analog simulation to improve the light intensity and precision of the light sources and using closed-loop feedback to control the illumination angle of the light sources.

Description

technical field [0001] The invention relates to a test light source generator and a test method, in particular to an arc sensor test light source generator and a test method thereof, which belong to the technical field of arc detection and protection. Background technique [0002] As a powerful measure for fault protection in the power industry, arc protection plays a vital role in the fault protection of power transmission and transformation systems. After many years of experience in arc protection, the arc and current dual-criteria scheme has been widely adopted. As we all know, in terms of current detection, the mechanism of current mutation or its phase mutation is used, and there is no hardware angle problem; while the arc sensor belongs to the category of hardware, and the optical detection has the parameter of receiving angle, so the arc sensor The test itself has an angular response characteristic. [0003] Although there are related products on the market, most of...
