Embodiment 1

[0034] Such as figure 1 , figure 2 As shown, a brush holder capable of monitoring temperature includes a brush box 1. The brush box 1 includes a mounting surface 101 on which a mounting head 2 is fixed. The mounting head 2 is used to install the brush box 1 and also includes a temperature monitoring chip. 3. The temperature monitoring chip 3 is arranged on the mounting surface 101 , the brush box 1 is provided with a carbon brush chamber 102 , and the temperature monitoring chip 3 is arranged outside the chamber wall of the carbon brush chamber 102 .

[0035] In this embodiment, the mounting head 2 is provided with a horizontal tapered dovetail boss, and the base 7 is provided with a horizontal tapered dovetail groove.

[0036] In order to control the temperature of the carbon brushes, an air supply device is installed near the brush holder to dissipate heat for the carbon brushes through the rapid flow of air. Due to the fast air flow near the brush holder, the heat of the...

Embodiment 2

[0042] Such as Figure 9-12 As shown, the difference from Embodiment 1 is that this embodiment includes a connection block 9 which is fixedly connected to the brush box 1 , and an antenna 8 is fixed on the connection block 9 . The connecting block 9 is fixed on the side of the brush box and is made of copper. The mounting surface 101 is provided with a chip groove 903 and a first wire hole 901, the temperature monitoring chip 3 is arranged in the chip groove 903, the connecting block 9 is provided with a second wire hole 902 connected with the first wire hole 901, and the chip wire 4 Connect to the antenna 8 through the first wire hole 901 and the second wire hole 902 .

[0043] In this embodiment, a linear antenna is used, which is widely used and low in cost. The chip wires 4 are arranged in the first wire hole and the second wire hole, so that they are not easily damaged by external force.

Abstract

The invention provides a brush holder capable of monitoring temperature. The brush holder comprises a brush box; the brush box comprises a mounting surface, and a mounting head is fixed on the mounting surface and used for mounting the brush box; the brush holder further comprises a temperature monitoring chip which is arranged on the mounting surface; the brush box is provided with a carbon brushchamber, and the temperature monitoring chip is arranged on the outer side of the chamber wall of the carbon brush chamber; and the brush holder further comprises a chip wire; one end of the chip wire is connected with the temperature monitoring chip, and the other end is connected with an antenna. According to the invention, the temperature monitoring chip is arranged on the back surface of thebrush box and the outer side of the chamber wall of the carbon brush chamber, so that the interval between the temperature monitoring chip and the carbon brush is small, the distance between the temperature monitoring chip and the carbon brush is short; the temperature change of the carbon brush can be accurately measured; the temperature monitoring chip is surrounded by multiple structures and prevented from being directly blown by cooling air, so that temperature measurement is accurate and reliable; a chip groove is formed in the mounting surface, and the chip is arranged in the groove, sothat the chip is can be further prevented from being directly blown by cooling air, and the measured temperature is more accurate; and the chip wire is arranged to be a concealed wire, so that the structure is simple, and the wire is protected from being damaged by external force.

Description

technical field [0001] The invention relates to the technical field of power accessories, in particular to a brush holder capable of monitoring temperature. Background technique [0002] A brush holder is disclosed in the excitation device of the Chinese invention patent (201610200489.6), which has a simple structure and stable operation. However, the carbon brush will generate a lot of heat during the working process. The brush holder disclosed in this patent cannot monitor the temperature of the carbon brush, and the stable use of the brush holder is not guaranteed. Contents of the invention [0003] The present invention provides a brush holder capable of monitoring temperature to overcome the above problems. [0004] A brush holder capable of monitoring temperature, comprising [0005] A brush box, the brush box includes a mounting surface, a mounting head is fixed on the mounting surface, and the mounting head is used for mounting the brush box; [0006] A temperat...
