Embodiment 1

[0046] A long-rod clamp-type ammeter, comprising a connecting rope 1, an insulating telescopic rod 2, a clamp-type ammeter head 4, the bottom of the clamp-type ammeter head 4 is detachably connected to a connector 5, and is electrically connected to an operating platform 6; the connector 5. The top end is detachably connected to the clamp-type ammeter head 4, and the bottom end is fixedly connected to the insulating telescopic rod 2; the insulating grip 3 is socketed with the bottom of the insulating telescopic rod 2, and is fixedly connected to the operating platform 6; the operating platform 6 is connected to the The insulating grip 3 is fixedly connected, and is electrically connected with the clamp-type ammeter meter head 4 through the hollow wire of the insulating telescopic rod 2 .

[0047] The top section of the connecting rope 1 is provided with toothed balls 28 at equal intervals, which cooperate with the bayonet gear 11 to work in transmission, the top of the connecti...

Embodiment 2

[0076] This embodiment is basically the same as Embodiment 1, except that the WiFi module used in this embodiment is directly connected to the smart phone, and each long-rod clamp-type ammeter is directly connected to the smart phone of the respective holder through WiFi;

[0077] At the same time, the mobile phone connected to the long rod clamp ammeter through WiFi is also connected to the same server through the 4G network;

[0078] During the detection process, the data detected by the long rod clamp ammeter is sent to the smartphone through the WiFi module, and the smartphone sends the data to the server through the 4G mobile phone. The server calculates the electricity consumption trend or leakage trend through the aggregated data and saves it and sends it back to the network. smartphone in.

Abstract

A long-rod clamp ammeter, comprising a connecting rope, an insulating telescopic rod, a clamp ammeter head, the bottom of which is detachably connected to a connector, and electrically connected to an operating platform; the connector is detachably connected to the clamp ammeter head, It is fixedly connected with the insulating telescopic rod; the insulating handle is socketed with the bottom of the insulating telescopic rod, and is fixedly connected with the operation platform; the operating platform is fixedly connected with the insulating handle, and is electrically connected with the head of the clamp-type ammeter through the hollow wire of the insulating telescopic rod. The insulating telescopic rod can adjust the required telescopic length arbitrarily, the meter head can adjust the direction, and the display can clearly display information without being affected by the angle.

Description

technical field [0001] The invention relates to the field of clamp-type ammeters, in particular to a long rod-type clamp-type ammeter and a circuit analysis method thereof. Background technique [0002] With the increasing development of the smart grid, the total leakage trip rate of the station area is an important indicator of the smart grid. At the same time, there is a lack of effective and fast means of detecting leakage current in the actual grid. Loss, troubleshooting is time-consuming, laborious and expensive. The routine inspection of leakage faults in the power supply station usually starts with a group of 2 people starting from the main outlet of the power distribution cabinet, climbing up the ladder at each node, clamping the clamp ammeter into the line along the wall, and then reading the value of the leakage current for judgment. . According to statistics, it takes an average of 2 hours to check the leakage in a single area. [0003] This project has realize...
