Description

Technical Field

[0001] The invention relates to the field of live working, and in particular to an intelligent anti-drop device for a live working fuse of an outdoor power distribution network. Background Art

[0002] In the prior art, in the distribution line equipment, drop-out fuses are the most common overload and short-circuit protection devices for 10kV distribution line branches and distribution transformers. As they are installed on the operating line for too long, and factors such as inadequate installation, operation and maintenance, they will lead to aging and rusting, contact heating, component damage and other phenomena. When dealing with this defect, in order to minimize the impact of power outage maintenance on power supply reliability, live operation and load replacement are usually adopted for replacement. At present, there are two problems in carrying out this operation scenario: 1. During the replacement of drop-out fuses under load, the drop-out fuses are susceptible to internal and external fault factors, causing them to fall off, resulting in abnormal power outages. When operators work near the fuses, there is a risk of electric shock to the operating electricians, and power outages to the line equipment.

[0003] 2. Due to the small phase-to-phase spacing of the fuse and the close distance to the grounding body, considering the range of human activities, the amplitude of movement and the requirement of minimum safety distance, there is a risk of touching different potentials (for example: relative to the ground, relative to the phase) at the same time.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The present invention provides an intelligent anti-drop device for live working fuses in an outdoor power distribution network. The working principle is to detect the current through a current detection mechanism, conveniently clamp the fuse through an electric telescopic clamping mechanism, and realize the intelligence and convenience of the use of the entire device through a control terminal mechanism, so as to achieve the purpose of automatically clamping and loosening the anti-drop device and the fuse tube, real-time monitoring of the fuse current, reducing the labor intensity of operators and ensuring operation safety.

[0022] The present invention is further described in detail below with reference to examples and specific implementation modes.

[0023] like Figure 1As shown, an intelligent anti-fall device for live working fuses of outdoor power distribution network comprises a multi-stage telescopic insulating rod 1, a current detection mechanism arranged on the multi-stage telescopic insulating rod, an electric telescopic clamping mechanism arranged on the multi-stage telescopic insulating rod, a control terminal mechanism for controlling the current detection mechanism and the telescopic actuator, a power supply mechanism arranged on the multi-stage telescopic insulating rod for powering the device, and a guide rod 6 arranged on the multi-stage telescopic insulating rod; the control terminal mechanism is connected to the current detection mechanism and the electric telescopic clamping mechanism; in: The top end of the multi-stage telescopic insulating rod is bent to form a hook portion 11 .

[0024] The current detection mechanism includes a current detection point 21 arranged at the center of the hook at the top of the multi-stage insulating telescopic rod and a wire 22 arranged inside the hook at the top of the multi-stage insulating telescopic rod, and the wire is connected to the current detection point; the electric telescopic clamping mechanism cooperates with the hook at the top of the multi-stage insulating telescopic rod to clamp the entire device on the porcelain bottle.

[0025] The electric telescopic clamping mechanism includes a telescopic actuator and a clamping actuator, and the telescopic actuator drives the clamping actuator. Specifically, the clamping assembly includes a fuse clamp 31 arranged on the multi-stage telescopic insulating rod and a worm 32 matched with the fuse clamp, the fuse clamp is arranged vertically, and the top end of the fuse clamp is installed on the multi-stage telescopic insulating rod and arranged by the hook; the center of the fuse clamp is provided with a through hole for the worm to pass through. The telescopic actuator includes a motor 33 driving the worm, and the motor drives the worm to move along the length direction of the worm.

[0026] The control terminal mechanism includes a wireless remote controller (similar to some existing wireless remote controllers, which will not be described in detail here) and a wireless transmission module 41 that cooperates with the wireless remote controller, and the wireless transmission module is connected to the motor and the wire. The wireless transmission module adopts 2.4G or LORA technology and can transmit and receive wireless signals. The wireless remote controller is equipped with a power switch, a clamping status indicator light, and a current fault indicator light.

[0027] The power supply mechanism includes a lithium battery 51 and a charging system for charging the lithium battery (charging the lithium battery is a relatively mature technology in the technical field and will not be described here). The charging system can charge the lithium battery with a fuse current; the lithium battery can power the motor. In actual operation, the lithium battery and the motor can be integrated into the body, and the housing as a whole can be installed on the multi-stage telescopic insulating rod, and the wireless transmission module can be integrated and set below the housing.

[0028] The top end of the guide rod is mounted on the multi-stage telescopic insulating rod, and the guide rod is provided with a guide hole for the worm to pass through, and the head end of the worm passes through the guide hole and the through hole provided on the fuse clamp in sequence.

Under the action of the motor, the worm 32 continuously moves toward the hook until the device is clamped. At this time, the wireless controller controls the multi-stage telescopic insulating rod to automatically retract to the working state to avoid occupying the working space. When the operation is completed, the wireless remote control controls the multi-stage telescopic insulating rod to the original state, and then controls the anti-drop device to the loose state, and the operator directly recycles it.

[0030] During the entire operation process, the current detection point 21 and the conductor 22 continuously perform current detection. When the operating current is detected to be 0A, an audible and visual alarm is issued to remind the staff [the audible and visual alarm is also a relatively mature technology and will not be elaborated here].

[0031] Wireless remote control is used throughout the entire operation, which allows operators to stay away from high-voltage lines, thereby improving the safety of workers.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
