Description

TECHNICAL FIELD

[0001] The utility model relates to temperature measuring device technical field, concretely relates to a general temperature measuring module of explosion -proof. BACKGROUND

[0002] In the industrial field, especially in each device area of oil refining, chemical industry and other heavy industrial enterprises, the application of large high and low voltage motors is extremely wide, and they are the key components for driving various mechanical equipment and realizing process flow. In order to ensure the safe and stable operation of these large motors, precise temperature measuring modules are specially designed on the side of the motor body. This module integrates three temperature measuring points of stator A, B and C three-phase coils, and two temperature measuring points of shaft extension bearings and non-shaft extension bearings, a total of five key temperature measuring positions. The data collected by these temperature measuring points is accurately transmitted to the DCS (Distributed Control System) or a special temperature control meter through high-quality transmission wires, and is displayed in the form of clear and intuitive numbers, which greatly facilitates the operation personnel to record data in real time and understand the equipment operation state comprehensively.

[0003] At present, the temperature measuring module commonly used in industrial practice generally adopts the mode of terminal connection to realize the effective connection between each temperature measuring point and transmission wire. Specifically, five temperature measuring points each need three outgoing lines to transmit temperature signals, and three transmission lines are needed to send these signals to the control system, so at least 30 contact points are needed for connection in the whole temperature measuring module. These contact points not only have a large number, but also have quite strict wiring process requirements to ensure the accuracy and stability of the signals.

[0004] The temperature measuring module, as a whole, is firmly installed on one side of the motor body, and has actually become an integral part of the motor. Therefore, when the motor needs to be sent for repair due to failure or regular maintenance, the operation personnel not only need to carefully remove the power cable of the motor, but also need to remove the temperature measuring cable one by one. Because of the numerous contact points in the temperature measuring module, the line number needs to be fixed carefully or clear marks need to be made every time it is disassembled, so that it can be accurately connected when reassembled. This operation process is quite complicated and time-consuming.

[0005] When the motor is reinstalled after repair, the operation personnel also need to reconnect the multiple temperature measuring cables according to the previous marks. If the line number is lost or the marks are unclear during this process, the cables need to be rechecked to ensure that all temperature measuring points can be correctly connected to the control system. This process requires high professional skills and experience of the operation personnel, and improper operation may cause serious consequences, not only affecting the normal operation of the motor, but also possibly affecting the whole device, causing significant economic loss and safety hazards.

[0006] In addition, for the explosion-proof temperature measuring module, the internal structure is often designed to be narrow and compact, and the wiring terminal occupies a lot of up and down space, which makes the operator face great operation difficulty when wiring, not only the work efficiency is not high, but also the temperature measuring module may be damaged or the wiring quality may be affected due to improper operation.

When it needs to be restored, the front cover 1 is only needed to be plugged back.
