Detailed Description

The following describes embodiments of the present invention in detail, which are developed based on the technical solutions of the present invention, and give detailed implementation manners and specific operation procedures to further explain the technical solutions of the present invention.

example 1

The embodiment provides an intelligent ball head link for flashover fault location, which is installed at one end of an insulator shown in fig. 2, and specifically shown in fig. 1, the intelligent ball head link includes a ball head link hardware 5, an induction module 1, a battery module 2, a control module 3 and a communication module 4; the induction module 1, the battery module 2 and the communication module 4 are all electrically connected with the control module 3, and the battery module 2 is also electrically connected with the communication module 4; the induction module 1, the battery module 2, the control module 3 and the communication module 4 are packaged into a whole, the induction module 1 is sleeved on the rod diameter of the ball head link hardware fitting 5, and the induction module 1 judges whether the ball head link hardware fitting 5 has power frequency current or not by adopting an electromagnetic induction principle.

The sensing module 1 comprises a sensing unit 11, a current limiting unit 12 and a current identification unit 13, wherein the sensing unit 11 and the current identification unit 13 are electrically connected with the current limiting unit 12, and the current identification unit 13 is electrically connected with the control module 3.

The induction unit 11 is composed of an induction coil, and the number of turns of the induction coil is calculated according to the voltage level and the transmission capacity of the power transmission line applied by the intelligent ball head hanging ring. Specifically, the maximum short-circuit power frequency current I1 is calculated according to the output voltage class and the transmission capacity applied by the intelligent ball head suspension loop, and then the number of turns of the coil required by the induction unit 11 is calculated.

the current limiting unit adopts a common current limiter, when the induced current collected by the induction unit 11 is too large, so that other units in the intelligent ball head suspension ring can be damaged, the current limiting unit 12 limits the induced current, and the other units are prevented from being damaged. The sensing unit 11 collects the sensing current as I0, and the current limiter 12 limits the current larger than I0, that is, the current limiter limits the sensing current collected by the sensing unit to the maximum value of I0.

If the insulator string at the mounting point of the intelligent ball-head suspension ring has flashover fault, large current can flow through the intelligent ball-head suspension ring and the tower connected with the uppermost insulator of the cross arm and the insulator string in the power frequency follow current, and finally the large current is released to the grounding device. At this time, the induction module 1 installed on the rod diameter of the ball head link fitting 5, specifically, the induction coil in the induction module 1, generates an induction current according to the electromagnetic induction principle. When the induction current is collected by the sensing unit 11, the current identification unit 13 generates a flashover fault signal (logic signal 0 or 1) and sends the flashover fault signal to the control module 3. The flashover fault signal wakes up the control module 3, so that the control module 3 is switched from a standby state to a working state, the control module 3 controls the communication module 4 to be switched from the standby state to the working state, and the line pole number, the longitude and latitude and the phase difference prestored in the control module 3 are sent to the monitoring platform through the communication module 4; the pre-stored line pole number, longitude and latitude and phase difference are the line pole number, longitude and latitude and phase difference of the target installation of the current intelligent ball head hanging ring. When the data (i.e. the pre-stored line pole number, longitude and latitude and the phase difference) is sent, the control module 3 and the communication module 4 are both switched to the standby state from the working state. Because the monitoring platform can be preset as a mobile terminal or a background server of a manager, when the manager receives the line pole number, the longitude and the latitude and the phase difference sent by the intelligent ball head hanging ring, the manager can quickly locate the accurate position of the flashover fault at the first time according to the data, so that the searching work of the flashover fault is effectively guided, and the labor intensity of operators can be reduced.

The communication module 4 adopts a public mobile network, and 2G, 3G, 4G and 5G are all possible. Because the data needing to be transmitted back are the line pole number, the longitude and latitude and the phase difference installed on the intelligent ball head hanging ring, and only relate to the text information, the communication module 4 can be realized by adopting a 2G network, and the cost can be reduced to the maximum extent.

the battery module 2 adopts a high-energy battery, and due to the intelligent ball head hanging ring, the default states of the control module 3 and the communication module 4 can be set to be standby states, only when flashover faults or preset routine detection occurs, the standby state is switched to a working state, and the standby state is switched back after data transmission is finished; in general, the probability of flashover faults occurring continuously in the same insulator string is limited, so that even if a sample test signal is sent, the electric energy consumed by the intelligent ball head hanging ring is low, and the replacement cost is low.
