Technical Field

The utility model relates to a power equipment field particularly, relates to a wireless temperature sensor installation mechanism and wireless temperature sensor.

Background

In the prior art, a passive wireless temperature sensor is usually used to directly contact with moving and static contacts, cable joints, bus joints, and lead joints such as transformers and isolation switches of various high and low voltage switch cabinets and ring main units, so that the temperature condition of the power equipment is transmitted to a background host in real time, the temperature condition is monitored in real time, and the safety of equipment operation is greatly improved. The temperature sensor is passively powered, the permalloy strip penetrates through the temperature sensor, the temperature sensor is bound at the position of the contact or the copper bar and the like, and the passive power supply of the temperature sensor is realized under the action of an electric field of the contact or the copper bar. How to design a reasonable structure, the permalloy strip penetrates through the temperature sensor and is bound on the contact or the copper bar, and the permalloy strip is a problem to be considered in the industry. The existing installation method mainly has the following problems:

1) and (3) enabling the alloy strip on the first side of the sensor host to pass through the rectangular groove of the steel ring, and enabling the inflection part to be flush with the steel ring by using sharp-nose pliers. The operation is complicated, and an operator needs to fold back the permalloy strip, align the bent part and clamp the bent part into the steel ring;

2) and inserting the alloy belt on the second side of the sensor host into the rectangular groove of the steel buckle, pinching the end part by using sharp-nose pliers, and forcibly turning inwards until the alloy belt is tightly adhered to the lower side to form a multilayer tubular structure. When operators turn over the roll with sharp nose pliers, the operator usually cannot control the turning-over degree. Especially for different operators, the force and the number of turns of the rolls are different. When the operator turns over too many turns with force, the sensor is excessively tied to the contact. On one hand, the temperature sensing piece of the temperature sensor is extruded and deformed, and even the temperature sensor is damaged by pulling. On the other hand, because the excessive roll-over is taut, binding in positions such as plum blossom contact when the sensor, can lead to the static contact to close a floodgate unsmoothly, can lead to the condition of unable normal closing more seriously, have certain potential safety hazard. Meanwhile, the permalloy belt tail part is of a multi-layer tubular structure, so that the mounting mechanism is more complex, the size is larger, the mounting space is occupied, and meanwhile, the hidden danger of partial discharge is increased.

3) The permalloy strip is finally bound by bolts on the steel buttons. On equipment such as a high-voltage switch cabinet and the like, the contact can generate high-frequency vibration in the opening and closing process, so that the bolt has the hidden trouble of loosening. Once the bolt loosens because of the vibration, drop into high-voltage apparatus the inside and produce the short circuit, can lead to serious electric power safety accident.

Therefore, the wireless temperature sensor is difficult to fix in the prior art.
