Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of a connector fault detection method according to an embodiment of the present invention.
In one embodiment of the present invention, as shown in fig. 2, the connector includes a moving contact and a plurality of fixed contacts, where the moving contact and the fixed contacts are connected through contacts, and when the moving contact and the fixed contacts are connected, whether the moving contact and the fixed contacts have faults is determined by acquiring the current temperature of the contacts and the color change of the currently connected fixed contacts when the moving contact and the fixed contacts are connected.
The movable contact is made of silver, the fixed contact is made of copper silver, the fixed contact is worn in the using process, and phenomena such as high temperature, oxidation and flashover arc can be generated in the wearing process, so that the surface material of the fixed contact is changed into silver oxide, copper oxide and copper oxide from silver, and different color changes can occur in the changing process, and therefore, the color sensor can be used for obtaining the surface color change of the material, and the wearing condition of the material is judged.
As shown in fig. 1, the connector fault detection method according to the embodiment of the present invention may include the following steps:
s1, when a moving contact is connected with a current fixed contact, acquiring the color of the current fixed contact.
Specifically, as shown in fig. 3, when the moving contact is connected with the current fixed contact, the color of the current fixed contact can be obtained through a color sensor arranged on the moving contact. It should be noted that, the color sensor may also be disposed on each static contact, so that in order to reduce the cost, the color sensor may be disposed on the moving contact, so as to obtain the color change of the static contact when the moving contact is connected with each static contact.
S2, acquiring the current temperature of the contact. In one embodiment of the invention, the contact temperature at the time of connecting the movable contact and the fixed contact can be obtained by a temperature sensor arranged on the contact of connecting the fixed contact and the movable contact.
And S3, judging whether the moving contact and the fixed contact have faults or not according to the color of the current fixed contact and the current temperature of the contact.
It should be noted that, because the static contact uses copper silver plating material, and the material surface that appears wearing and tearing in the use changes into from silver, silver oxide, copper, cupric oxide, and under the condition that the material surface changed, the material surface colour also can change, and the change course is: silver, tan/tan, mauve, black. Since the colors of silver oxide and copper oxide are very close, it is necessary to obtain a change in color of the material surface, for example, from silver to tan/tan, or from tan/tan to mauve, etc. In one embodiment of the invention, it is difficult to determine whether the moving contact or the fixed contact is faulty or not only by means of color change, and the contact temperature when the moving contact and the fixed contact are connected needs to be combined for determination.
According to one embodiment of the invention, judging whether the moving contact and the fixed contact have faults according to the color of the current fixed contact and the current temperature of the contact comprises the following steps: when the color of the current static contact is unchanged and the current temperature of the contact exceeds a preset temperature threshold, judging that the moving contact fails. The preset temperature threshold value can be calibrated according to practical situations, for example, the highest temperature allowed by the contact. In one embodiment of the present invention, when determining that the moving contact is abnormal, the method further includes: and switching the moving contact into a standby moving contact. That is, when judging that the moving contact fails, in order to ensure normal operation, the moving contact is directly switched into a standby moving contact, and the standby moving contact is also provided with a color sensor, so that the influence on the connection characteristic can be avoided, and the automatic operation and maintenance function is realized.
Further, according to an embodiment of the present invention, when the color of the current fixed contact changes and the current temperature of the contact does not exceed the preset temperature threshold, it is determined that no fault occurs in both the moving contact and the current fixed contact.
Specifically, whether the moving contact and the current fixed contact have faults or not can be determined according to the color change of the fixed contact and the contact temperature. For example, when the color of the current static contact is not changed but the contact temperature is abnormal, the current static contact is indicated to work normally, and the moving contact is failed, so that the contact temperature exceeds a preset temperature threshold value; for another example, when the color of the current static contact is changed (for example, from silver to tan/brown black), but the contact temperature is normal, the current static contact and the moving contact are both normal, and no fault occurs.
It should be noted that, when the color of the current static contact is changed (for example, from purple to black), and the contact temperature is abnormal, the contact temperature may be increased because the surface material of the current static contact is worn greatly, and the contact temperature may be increased because the moving contact is abnormal.
In one embodiment of the present invention, when the color of the current fixed contact changes and the current temperature of the contact exceeds a preset temperature threshold, determining whether the current fixed contact has a fault according to the contact temperature of the fixed contact and the moving contact, including: the control brake contact moves and is connected with the static contact except the current static contact; and when the contact temperature does not exceed the preset temperature threshold, judging that the current static contact fails.
That is, by moving the moving contact to the next stationary contact, when the moving contact is connected to the stationary contact, the color change and the contact temperature of the stationary contact are obtained, regardless of whether the color of the stationary contact is changed, when the contact temperature is normal, it is indicated that the moving contact is normal, and the current stationary contact fails.
In another embodiment of the present invention, when a current color of a current static contact changes and a current temperature of a contact exceeds a preset temperature threshold, determining whether a fault occurs between a moving contact and the current static contact according to a standby contact temperature at which the standby moving contact is connected with the current static contact includes: the temperature of a standby contact point of the standby moving contact point connected with the current fixed contact point is obtained; when the temperature of the standby contact exceeds a preset temperature threshold, judging that the current static contact fails; and when the temperature of the standby contact does not exceed the preset temperature threshold, judging that the moving contact fails.
That is, when switching to the backup movable contact, the backup movable contact is set to be in normal operation by default, when the backup contact is at a normal temperature, the movable contact is determined to be in failure, and when the backup contact is at an abnormal temperature, the stationary contact is determined to be in failure.
According to one embodiment of the present invention, when judging that the current static contact fails, the method further includes: and shielding the position of the current fixed contact so that the movable contact is not connected with the current fixed contact.
That is, when judging that the current fixed contact fails, the current position is shielded, namely the moving contact is not connected with the fixed contact any more in the moving process, so that potential safety hazards caused by connection under the fault condition can be avoided.
In summary, the invention firstly obtains the color of the current static contact and the current temperature of the contact when the moving contact is connected with the current static contact; and judging whether the moving contact and the fixed contact are abnormal or not according to the color of the current fixed contact and the current temperature of the contact, so that whether the connector fails or not can be rapidly and accurately judged, potential safety hazards are reduced, and meanwhile, the operation and maintenance cost is reduced.
