Abstract
The utility model relates to a contact temperature-sensitive alarm nut, characterized in comprising an alarm indicator cap and a pedestal, wherein the alarm indicator cap has a sleeve structure and is fixedly equipped with a permanent magnet at the centre of the lower surface, the centre of the upper surface of the pedestal is fixedly equipped with a temperature-sensitive material, the inside of the pedestal is equipped with a screw hole mountable on a bolt, the alarm indicator cap is vertically and slidably mounted on the outer portion of the pedestal, the permanent magnet and the temperature-sensitive material are adhered to each other, and a spring is sleeved on the outside of the permanent magnet and the temperature-sensitive material. The contact temperature-sensitive alarm nut is reasonably designed, is mounted at a power transmission line contact, and realtimely monitors the temperature of the power transmission line contact by utilizing the principle that temperature variation changes the amount of magnetic field force and by utilizing the temperature-sensitive characteristic of the temperature-sensitive material, if the monitored temperature exceeds a preset temperature, the alarm indicator cap jumps, the red pedestal is seen, convenient for tour personnel to timely discover, thus knowing the change of the temperature of the power transmission line contact, eliminating the safety hidden trouble of system operation, and ensuring the normal operation of system equipments.
Description
Technical field
The utility model belongs to transmission of electricity power transformation technical field, especially a kind of contact temperature-sensitive warning nut.
Background technology
Many equipment in the electric system are in the day-to-day operation process, and the equipment self temperature some can take place changes, and these situations of change have often reflected the ruuning situation of equipment.For example, if the temperature that the bearing of equipment, motor, transmission line of electricity joint etc. are located raises suddenly, then devices illustrated breaks down at this moment or has potential faults, if continue operation, with security of operation that has influence on equipment and serviceable life.Therefore, in electric system, be badly in need of some equipment in the electric system is carried out that real time temperature detects and makes the warning action reaching predetermined temperature.At present, still not having such temperature detection and warning device is applied in the electric system.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of contact temperature-sensitive warning nut that can accurately detect the power system device temperature and in time report to the police is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of contact temperature-sensitive warning nut; Comprise report to the police indication cap and base; This warning indication cap is tube-in-tube structure and installs a permanent magnet in its lower surface central authorities, installs a temperature sensing material and in base, is provided with the screw that can be installed on the bolt in the upper face center of base, and the indication cap of reporting to the police slides up and down and is installed in base exterior; Permanent magnet and temperature sensing material are pulled together, suit one spring outside permanent magnet and temperature sensing material.
And; The mounting means of described warning indication cap and base is: outside base, be shaped on the locating slot that the indication cap of reporting to the police is moved up and down, the hold-down nut and the locating slot of indicating cap to be fastened on base exterior and radially being provided with through the indication cap of reporting to the police of reporting to the police is installed together.
And described warning indication cap is the circular sleeve structure, and described base is the circular cylinder structure.
And described base is red circular cylinder structure.
The advantage and the good effect of the utility model are:
The utility model is reasonable in design, and it is installed in transmission line of electricity contact place, and the utilization temperature variation changes the principle of magnetic field force size and utilizes the temperature-sensitive characteristic of temperature sensing material to monitor the temperature of transmission line of electricity contact in real time; When if the temperature that monitors surpasses its predefined temperature; The indication cap of then reporting to the police is upspring, and exposes red base, is convenient to the tour personnel and in time finds; Thereby grasp the variation of transmission line of electricity contact temperature; Avoid the generation of accident, eliminated the potential safety hazard of system's operation, guaranteed the normal operation of system equipment.
Description of drawings
Fig. 1 is that the master of the utility model looks cut-open view;
Fig. 2 is the constitutional diagram of Fig. 1 after the indication cap of reporting to the police is upspring.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
A kind of contact temperature-sensitive warning nut, as shown in Figure 1, comprise report to the police indication cap 1, base 4; This warning indication cap is the circular sleeve structure and installs a permanent magnet 7 in lower surface central authorities; Base is red cup dolly, installs a temperature sensing material 6 in the upper face center of base, in base, is provided with the screw 8 that can be installed on the bolt; Outside base, be shaped on the locating slot 5 that the indication cap of reporting to the police is moved up and down; The indication cap spiral-lock of reporting to the police is installed together with locating slot in base exterior and the hold-down nut 3 that radially is provided with through the indication cap of reporting to the police, and permanent magnet and temperature sensing material are pulled together, suit one spring 2 outside permanent magnet and temperature sensing material; When raising, the temperature sensing material temperature make attractive force between permanent magnet and the temperature sensing material descend and during less than the elastic force of spring; The indication cap of reporting to the police is upspring under the effect of spring and moved up along locating slot, makes the middle and upper part branch of base be exposed out, and is as shown in Figure 2.
The utility model is installed in it on the bolt of transmission line of electricity by the contact place through the screw under the base in use, along with the rising of contact temperature and when reaching preset alarm temperature; Temperature sensing material loses ferromagnetism, and permanent magnet descends rapidly to the attractive force of temperature sensing material, when attractive force during less than the elastic force of spring; The indication cap of reporting to the police is upspring under the effect of spring; Expose red base, expression has surpassed alarm temperature, waits for that the tour personnel find and handle.
The utility model can be widely used in 110kV and the 35kV circuit, can real-time monitor the up-set condition of line contacts temperature, temperature error≤± 2 of temperature-sensitive nut monitoring ℃; Alarm temperature can customize by arbitrary temp point between 40 ℃ to 150 ℃, for example is located at 60 ℃, and 70 ℃, 80 ℃, 90 ℃.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
