Problems solved by technology

The traditional ways of installing sensors generally include: (1) apply glue to the back of the temperature measuring sensor, and paste it directly to the contact, and the glue will age for a long time, resulting in the phenomenon that the sensor is easy to fall off; (2) use a heat shrinkable sleeve to wrap the The sensor sleeve is clamped on the static contact at the joint, and the heat shrinkable tube also has the defect that it will age for a long time, and the heat shrinkable tube also has the defect that the temperature is too high (over 125°C) and it is easy to crack, which makes the sensor easy to fall off (3) At present, there is another method is to punch holes on the electrical busbar at the joints, and then use the newly punched holes to install the sensors on the joints with fasteners. This method is mostly used in electrical transformation. And re-drilling holes on the bus will affect its conductive performance, and it is inconvenient

Embodiment 1

[0017] As shown in Figure 3, when installing sensors on the joints of two electrical bus bars 5 connected by connecting bolts 6 and nuts 7, firstly pass the mounting bolts 6 through the mounting holes on the bus bars 5, and then insert the mounting part of the mounting base 1 Put it on the mounting bolt 6 in the form of a gasket, tighten the nut 7, and then clamp the probe 4 of the temperature sensor with the clamp 3 on the fixed part 2 of the mounting base.

[0018] For the electrical contacts that just need to be retrofitted and installed with temperature measuring sensors in the old electrical system, it is only necessary to first remove the nuts 7 on the mounting bolts 6 connected to the electrical busbar 5, and then put the mounting part 1 of the mounting seat on it in the form of a gasket. After installing the bolt 6, tighten the nut 7, and then clamp the probe 4 of the temperature sensor with the chuck 3 on the fixed part 2 of the mounting base.

Embodiment 2

[0020] As shown in Figure 4, when the sensor is installed on the contact of two electric bus bars 5 connected by the static contact 8 and the moving contact 9, the mounting bolt 6 is first passed through the mounting hole on the static contact 8, and then the The mounting part 1 of the mounting seat is set on the mounting bolt 6 in the form of a gasket, and then the nut 7 is tightened, and then the probe 4 of the temperature sensor is clamped with the clamp 3 on the fixing part 2 of the mounting seat.

[0021] For the electrical contact that just needs to be modified and installed in the old electrical system to install the temperature sensor, it is only necessary to remove the nut 7 on the mounting bolt 6 that passes through the mounting hole on the static contact 8, and then install the mounting part 1 of the mounting base with The gasket form is set on the mounting bolt 6 and then the nut 7 is tightened, and then the probe 4 of the temperature sensor is clamped with the clam...

Abstract

An erection base of transducer fro measuring temperature at electric contact is prepared as applying metal material to make said base and forming said base by erection unit including thin plate with erection hole on it for fixing electric contact and fixture unit being an integral structure extended out along planar level of said thin plate. The method for erecting transducer by utilizing said base is also disclosed.

Description

technical field [0001] The invention relates to an installation seat of an electric contact temperature measuring sensor and an installation method of the sensor. Background technique [0002] The temperature of wires, switches, and equipment contacts in electrical circuits is a very important data. It involves the capacity and operating status of the circuit, and is the necessary data to analyze the safe operation of the circuit. Generally, the temperature measurement methods for electrical contacts include direct instrument measurement and sensor indirect instrument measurement. Direct instrument measurement has the defects of inconvenient measurement, discontinuous data, and not real-time. In the prior art, sensor indirect instrument measurement needs to use wires to connect the sensor to the instrument. Although it can conveniently measure continuous and real-time data, it may be unsafe in the case of high contact voltage due to its connection wit...
