Embodiment 1

[0037] The embodiment is basically as Figure 1 to Figure 6 As shown: this embodiment provides a metal-enclosed switch main bus temperature measuring device, the temperature measuring device includes a bushing 1, an insulating boot 2, a temperature measuring plug 3 and a protective cap 4, and the temperature measuring device passes through the bushing 1 is installed at the opening of the metal-sealed switch box body 5 and ensures a sealed connection; specifically, a first conductor 11 passing through both ends of the bushing 1 is provided inside the bushing 1, and the bushing 1 is formed around the first conductor. Protective layer 12, the design of the protective layer 12 can prevent the first conductor 11 from being damaged by mechanical or heat, the lower end of the first conductor 11 is fixedly connected with the main bus bar 6 in the metal-sealed switch, and its upper end passes through the bushing 1 and connects with the The temperature measuring plug 3 is fixedly connec...

Embodiment 2

[0047] Embodiment 2 is basically the same as Embodiment 1, the difference is: please combine figure 1 , 4 and Figure 5 As shown, this embodiment provides a temperature measuring device for the main bus bar 6 of a metal-enclosed switch. In order to facilitate the installation of the bushing 1 and the temperature measuring plug 3 in the insulating boot 2, the insulating boot 2 provided by this embodiment has The hollow structure of the tapered inner cavity allows the bushing 1 and the temperature measuring plug 3 to be respectively inserted into the tapered inner cavity at both ends of the insulating boot 2 and matched therewith. Furthermore, a step extending along the direction of the above-mentioned boss is also provided on the outer wall of the sleeve 1, and a third stepped surface 124 is formed. The first mating surface 212 that matches the three stepped surfaces 124; at the same time, a raised portion extending outward is provided on the temperature measuring plug 3, and...

Abstract

The invention discloses a temperature measuring device for a main bus of a metal-enclosed switch, and relates to the technical field of temperature measurement of power equipment. The temperature measuring device comprises a sleeve, an insulating boot, a temperature measuring plug and a protective cap, wherein a first conductor penetrating through the two ends of the sleeve is arranged in the sleeve, and the two ends of the first conductor are fixedly connected with the main bus and the temperature measuring plug respectively; the sleeve and the temperature measuring plug are sleeved in the insulating boot, and the insulating boot is connected with the external part in a grounding manner so as to enable the insulating boot to form a grounding layer; the temperature measuring plug comprisesa second conductor and a shell, and the second conductor is connected with the first conductor; and an intelligent temperature measuring module for measuring the temperature of the second conductor is embedded in the temperature measuring plug, and the intelligent temperature measuring module is externally connected through a wireless signal. By implementing the technical scheme, the technical problem that the temperature of the main bus in the metal-enclosed switch box body is difficult to monitor in the prior art can be effectively solved, and the online accurate monitoring of the main busof the metal-enclosed switch can be effectively realized. The temperature measuring device has the characteristics of stable and reliable structural connection, convenient installation and operation and low maintenance cost, and has an excellent application prospect.

Description

technical field [0001] The invention relates to the technical field of temperature measurement of electric power equipment, and more specifically, relates to a main busbar temperature measurement device applied to a metal-enclosed switch. Background technique [0002] Metal-enclosed switchgear is a new generation of electrical products designed and developed successfully by introducing advanced technology and in accordance with domestic rural power and domain network transformation requirements.
