Problems solved by technology

[0003]However, the existing air compressor in the substation only records the starting time, and the equipment defect level needs to be graded according to the number of times the air compressor is started
To solve this problem, the conventional method is to connect the counter in series with the power circuit in the control box of the air compressor to increase the function of recording the number of starts. However, the space of the control box of the air compressor is small, and it is not convenient to install the counter. When installing the counter, The air compressor needs to be powered off, causing the air compressor to fail to replenish compressed air in time

Embodiment 1

[0031] Such as Figure 1 to Figure 5 As shown, an air compressor start-up recording device provided in this embodiment includes a power generation module 1 , a current detection module 2 and a display module 3 . Wherein, the power generation module 1 is fixed on the outside of the air compressor shell, and the power generation module 1 can generate electricity by using the air flow of the air compressor, and then supply power to the current detection module 2, and there is no need to set up a battery to power the current detection module 2, which can save energy consumption. Electricity, specifically, the power generation module 1 can be fixed on the air guide protection net of the air compressor; the current detection module 2 is fixed on the power line of the air compressor, the current detection module 2 is electrically connected with the power generation module 1, and the current detection module 2 It is used to detect the current of the air compressor; the display module ...

Embodiment 2

[0048] The recording device for starting times of an air compressor provided in this embodiment differs from the recording device for starting times of an air compressor provided in Embodiment 1 only in that the casing 11 of the power generation module 1 is pasted on the outside of the casing of the air compressor. When the casing 11 of the power generation module 1 is not convenient to be fixed on the outside of the air compressor casing by magnetic attraction, the casing 11 of the power generation module 1 can be pasted on the outside of the air compressor casing, for example, the casing 11 of the power generation module 1 The casing 11 can be pasted and fixed on the outside of the air compressor casing by double-sided adhesive tape.

[0049] The rest of the structure of this embodiment is the same as that of Embodiment 1 and will not be repeated here.

Abstract

The invention belongs to the technical field of air compressors, and discloses an air compressor starting frequency recording device which comprises a power generation module. The power generation module is fixed to the outer side of an air compressor shell and generates power through airflow of the air compressor. A current detection module is fixed to a power line of the air compressor and is electrically connected with the power generation module. The current detection module is used for detecting the current of the air compressor. A display module is configured to display the starting frequency of the air compressor according to detection data of the current detection module. According to the air compressor starting frequency recording device provided by the invention, the power generation module is fixed to the outer side of the air compressor shell and generates power through the airflow of the air compressor so as to supply power to the current detection module, a battery does not need to be arranged to supply power to the current detection module, and electricity is saved. The display module accurately displays the starting times of the air compressor according to the detection data of the current detection module. The device is convenient and fast to install and small in size, and does not occupy the space in the compressor shell.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an air compressor startup times recording device. Background technique [0002] Pneumatic circuit breakers in substations need air compressors to provide compressed air. When air leakage occurs in the circuit breaker mechanism or the air pipeline, the air compressors will start frequently. The staff need to judge the defect level of the equipment based on the number of starts of the air compressors. [0003] However, the existing air compressors in substations only record the starting time, and the equipment defect level needs to be graded according to the number of times the air compressors are started. To solve this problem, the conventional method is to connect the counter in series with the power circuit in the control box of the air compressor to increase the function of recording the number of starts. However, the space of the control box of the air compressor is sm...
