Embodiment Construction

[0009] Digital oil temperature gauge, such as figure 1 As shown, it includes a housing 33 and a temperature measuring probe 9, a temperature display 34 is installed on the housing 33, a PCB circuit board and a processor are arranged in the housing 33, and the PCB circuit board is connected to the temperature measuring probe 9; button 8. The temperature measuring probe 9 extends into the oil tank to measure the oil temperature, and the temperature data is fed back to the PCB circuit board, which is processed by the processor and displayed on the temperature display 34 in real time. The inner shell 33 is provided with a control groove 3, and the design of the inward depression can prevent dust from entering directly. The control button 8 is arranged in the control groove 3, two fixed disks 4 are arranged on the inner shell 33 on both sides of the upper part of the control groove 3, and a rotating rod 2 is arranged between the two fixed disks 4, and the rotating rod 2 rotates re...

Abstract

Disclosed is a digital oil temperature gauge. The digital oil temperature gauge comprises a shell and a temperature measurement probe. A temperature displayer is mounted on the shell, a PCB and a processor are arranged inside the shell, and the PCB is connected with the temperature measurement probe. The shell is provided with control buttons. A control groove is formed in an inner shell, and the control buttons are arranged in the control groove. Two fixing disks are arranged on the inner shell on the two sides of the upper portion of the control groove, a revolving bar is arranged between the two fixing disks, and the revolving bar rotates relative to the fixing disks. The revolving bar is connected to the upper end of a dustcloth, hanging rings are arranged at the lower end of the dustcloth, hanging buckles are arranged on the inner shell of the lower portion of the control groove, and the hanging rings are matched with the hanging buckles. The revolving bar is provided with a torsional spring, one end of the torsional spring is connected with the revolving bar, and the other end of the torsional spring is connected with the fixing disks. By means of the digital oil temperature gauge, real-time temperature monitoring can be achieved, and the using safety of a transformer is guaranteed; a large amount of dust can not enter the control buttons, so that a control device is effectively protected, and the service life is prolonged; the dustcloth can be lifted conveniently, using of the control buttons can not be affected, and opening and closing are convenient.

Description

technical field [0001] The invention relates to an electric power tool, specifically a digital oil temperature gauge. Background technique [0002] During the operation of the transformer, the oil temperature in the transformer is an important parameter. Through the understanding of the parameters of the oil temperature, the operation status of the transformer can be grasped in time to ensure the safety of use. The measurement device has been used outdoors for a long time, and the use environment is relatively harsh. Dust often enters the control equipment and causes failure, which affects the normal measurement. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a digital oil temperature gauge. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a digital oil temperature gauge, including a housing and a temperature measuring prob...
