Abstract
Description
Technical Field
[0001] The utility model relates to switch cabinet temperature monitoring equipment, in particular to an outlet bushing temperature measuring device. Background Art
[0002] Power system equipment often ages or overheats during long-term operation. If not discovered and resolved in time, it may cause serious fire accidents. Due to the remote location of substation equipment, managers cannot be comprehensive in terms of maintenance and monitoring, making inspection and maintenance difficult. Therefore, it is necessary to realize remote temperature monitoring and temperature warning systems through automation, which has become an important means for managers.
[0003] The passive wireless temperature measurement system of the switch cabinet is mainly composed of temperature sensors, temperature collectors, temperature measurement main control terminals and monitoring application systems. The function of the temperature collector is to collect the temperature of the contact points of the substation equipment such as switches and switches. The temperature collectors are arranged at multiple points as needed. The temperature sensor aggregates the temperature data collected from multiple points of multiple switch cabinets, and transmits the data to the temperature measurement main control terminal through the wireless network. The temperature measurement main control terminal then uses the monitoring application system to store, count, analyze and warn the data.
[0004] The existing temperature measurement method is usually to measure the temperature of the outlet bushing. The outlet bushing temperature measurement device currently used generally sets the temperature sensor and antenna directly on the magnetic steel belt. When in use, the magnetic steel belt is clamped on the outlet bushing and locked with screws. Although this temperature measurement device has a simple structure and low cost, it is easy to loosen after long-term use, which will cause a gap between the sensing end of the temperature sensor and the outlet bushing, and it cannot fit tightly. In addition, it is difficult to find that the magnetic steel belt has loosened in daily use, resulting in inaccurate temperature measurement data and failure to play a warning role. Summary of the invention
[0005] The technical problem to be solved by the utility model is to provide a temperature measuring device for an outlet casing, which has the advantages of small size, convenient installation, not easy to loosen during use and convenient maintenance.
[0006] In order to solve the above technical problems, the technical solutions adopted are as follows:
[0007] The outlet bushing temperature measuring device comprises a temperature sensor, an antenna and a magnetic steel belt, wherein the signal output end of the temperature sensor is electrically connected to the signal input end of the antenna, and the temperature sensor is arranged on the magnetic steel belt. The device is characterized in that: it also comprises an annular mounting shell and an elastic pad, wherein a first mounting groove and a second mounting groove are arranged in the annular mounting shell, the temperature sensor and the elastic pad are arranged in the first mounting groove, and the elastic pad is arranged on the outside of the temperature sensor, a first notch connected to the first mounting groove is arranged on the inner side surface of the annular mounting shell, and the detection end of the temperature sensor extends from the first notch to the inner side of the annular mounting shell; the antenna is arranged in the second mounting groove, and the first mounting groove and the second mounting groove are connected.
[0008] In the above-mentioned outlet bushing temperature measuring device, the shape of the annular mounting shell matches the shape of the outlet bushing. When in use, the annular mounting shell is sleeved on the end of the outlet bushing, and the temperature sensor maintains contact with the outlet bushing under the action of the elastic pad. The magnetic steel belt induction draws electricity through the outlet bushing to provide power for the temperature sensor, and can collect temperature data at all times. Compared with tightening the temperature sensor on the outlet bushing through the magnetic steel belt, the annular mounting shell is easy to install and disassemble, can better cooperate with the outlet bushing, so that the sensing end of the temperature sensor fits the outlet bushing, and the annular mounting shell is not easy to loosen. Even if the annular mounting shell is deformed after long-term use, the temperature sensor can still maintain a close fit with the outlet bushing under the action of the elastic pad, which will not affect the temperature measurement.
[0009] In a preferred embodiment, at least one limiting guide groove extending inward and outward is formed on the side wall of the first installation groove, and at least one limiting guide block matching the limiting guide groove is provided on the temperature sensor, and the limiting guide block is located in the corresponding limiting guide groove. The temperature sensor can move inward and outward along the limiting guide groove through the limiting guide block, and the limiting guide block can also limit the temperature sensor, thereby preventing the temperature sensor from falling from the first notch under the action of the elastic pad.
[0010] In a preferred embodiment, at least one inwardly protruding installation stop block is provided on the inner wall of the annular installation shell. A second notch matching the installation stop block is provided on the outlet sleeve. When the annular installation shell is sleeved on the outlet sleeve, the installation stop block can limit the position of the annular installation shell to prevent the annular installation shell from rotating.
[0011] In a preferred embodiment, the elastic pad is made of an elastic silicone pad.
[0012] The beneficial effects of the utility model are that the outlet bushing temperature measuring device is small in size, easy to install, not easy to loosen during use, and easy to repair. BRIEF DESCRIPTION OF THE DRAWINGS
