Throwing-hanging type grounding hook with monitoring function

Abstract

The invention discloses a throwing-hanging type grounding hook with a monitoring function. The grounding hook comprises a grounding hook body, a wire clamping hook tongue, a monitoring module and a hook. The grounding hook is characterized in that the monitoring module is installed on the wire clamping hook tongue; an electrode and a hook body electrode screw connected with the wire clamping hooktongue are arranged on the monitoring module; the electrode and the hook body electrode screw are respectively connected with a wire hanging detection circuit in the monitoring module through leads; the electrode and the wire clamping hook tongue are mutually insulated, circuit bare wires hung on the grounding hooks make contact with the electrodes and the wire clamping hook tongues to form an electrical connection loop, the electrical connection loop is connected with the monitoring module through wires, and the monitoring module transmits detected information to the system cloud platform server. According to the invention, the problem that the ground wire is difficult to hang in the current ultrahigh-voltage line construction operation is solved, the wire hanging state detection of the ground hook can be accurately completed, the working state of the used ground hook can be timely and accurately understood by the working personnel in the use field and the background of the remote monitoring center, and the casualty accident of accidental electric shock caused by illegal operation is avoided.

Description

technical field [0001] The invention relates to a throwing-type grounding hook, in particular to a throwing-type grounding hook for real-time monitoring of the grounding use state. Background technique [0002] At present, when high-voltage lines are under power outage maintenance, in order to avoid accidental power transmission or inductive electricity on the line, which may cause electric shock accidents to workers, a short-circuit ground wire is hung on the line, and the line is directly short-circuited to the ground. If the line is not hooked up properly and the hooking position is incorrect, it will bring great safety hazards to the on-site staff. Personal protection measures are useless, and the security situation is severe.

Problems solved by technology

[0002] At present, when high-voltage lines are under power outage maintenance, in order to avoid accidental power transmission or inductive electricity on the line, which may cause electric shock accidents to workers, a short-circuit ground wire is hung on the line, and the line is directly short-circuited to the ground. If the line is not hooked up properly and the hooking position is incorrect, it will bring great safety hazards to the on-site staff. Personal protection measures are useless, and the security situation is severe.

At present, the grounding wire is used to connect the line conductor mainly through the grounding hook (rod) and the grounding wire clamp. The grounding hook (rod) needs to be hung up through the insulating operating rod. In order to ensure personal safety, the relevant standards stipulate the length of the insulating operating rod. On the transmission line with high voltage level, it is difficult to use the operating lever because it is relatively long and heavy. When the grounding clamp is used, it is tied to the grounding clamp by an insulating rope. , the line conductor touches the locking device of the clamp to close the clamp and clamp the line conductor. When used on a transmission line with a high voltage level, since the operator operating the ground clamp is more than 7 meters away from the line conductor below, the operator will place the ground wire It is difficult to align the clip with the line conductor, especially in windy weather. In addition, the line conductor is not directly below the operator on the corner tower, so the grounding clamp cannot be used.
