Circulation monitoring device of intelligent cable grounding device

Abstract

The invention discloses a circulation monitoring device of an intelligent cable grounding device. The circulation monitoring device comprises a monitoring device body, the monitoring device body is composed of a protective cover, a mounting plate, a wire harness clamping and fixing bottom frame, a wire harness movable pressing frame and butterfly-shaped knobs. The bottom of the protective cover isdetachably connected with the front surface of the mounting plate; a wiring terminal panel is arranged at one end of the protective cover; the wire harness clamping bottom frame is located right in front of the wiring terminal panel. Two fixed seats are symmetrically arranged at two ends of the front surface of the mounting plate; the wiring harness movable pressing frame comprises two rotating rods, one ends of the two rotating rods are rotatably connected with the two fixing bases respectively, the number of the butterfly-shaped knobs is two, two threaded rods are symmetrically arranged onthe portions, located at the two sides of the interval between the wiring harness clamping and fixing bottom frame and the wiring terminal panel, of the front face of the installation plate, and eachbutterfly-shaped knob can be in threaded connection with the corresponding threaded rod. According to the invention, the wire harness is not easy to loosen and fall off, the phenomenon that the tail part of the wire harness joint is excessively bent is avoided, and the service life of the wire harness is prolonged.

Description

technical field [0001] The invention mainly relates to the technical field of an on-line monitoring device for grounding circulation, in particular to a circulation monitoring device for an intelligent cable grounding device. Background technique [0002] With the rapid development of China's economy, the demand for electricity is gradually increasing, and the proportion of power cables is gradually increasing. In recent years, the use of high-voltage cables and accessories has increased dramatically year by year, and the number of high-voltage cables and accessories put into operation every year has increased from less than 10% to 15%-20%, which has also brought heavy cable maintenance work. . [0003] However, the wiring ports of the existing cable grounding circulation on-line monitoring devices are generally directly inserted into the harness connectors.

Problems solved by technology

In recent years, the use of high-voltage cables and accessories has increased dramatically year by year, and the number of high-voltage cables and accessories put into operation every year has increased from less than 10% to 15%-20%, which has also brought heavy cable maintenance work.

[0003] However, the wiring ports of the existing cable grounding circulation on-line monitoring devices are generally directly inserted into the harness connectors. During the wiring construction process in the machine room, if the corresponding harness is accidentally pulled, the connectors will loosen, resulting in poor contact. phenomenon, and the installation position of the cable grounding circulation online monitoring device is not relatively fixed, it may be installed vertically or parallel, and the installation height may be high or low, resulting in the need to bend the joint part of the wire harness. In the case of long-term bending It is easy to break due to aging

[0004] For example, a circulating current monitoring device for an intelligent cable grounding device provided by the patent document (publication number CN209327482U) includes an upper cover, a front panel, a base, a rear panel, an ordinary intelligent host, an indicator light, a fixing hole, a fixing groove, a battery interface, Solar interface, circulation interface, first serial port, second serial port, first power output port, second power output port, 485 interface, CAN interface, zone interface, SIM card slot, DIP switch, antenna interface, reset button, There is no fixed structure of the wire harness on the side of the corresponding terminal, which can easily cause the above-mentioned wire harness to loosen or fall off.

[0005] Another example is a circulating current monitoring device for an intelligent cable grounding device provided by the patent document (publication number CN111239442A), which includes a base plate, a shell plate with a U-shaped structure is fixed on the top of the base plate, and both sides of the shell plate are fixed with A fixed plate, one of which is provided with a power connector, an electrical connector, an output connector, and a zone interface, and a protective cover is fixed on the fixed plate, and the outer part of the protective cover is provided with a power connector and an electrical connector. , the output joint, and the corresponding wiring port of the defense zone interface, the inner ferrule of the wiring port has a rubber sleeve, the front of the protective cover is provided with a rectangular opening, and locking plates are fixed on both sides of the front of the protective cover. Under the joint action of each component, it is easy to open and close the slide plate, so as to facilitate the operation and connection of the connecting line, and after the connection, the slide plate can be tightly covered on the rectangular opening, so that it has a better dust-proof effect as a whole , and achieve the effect of further fixing the wires. The main purpose of the circulation monitoring device of the intelligent cable grounding device is to prevent dust, and at the same time take into account a certain effect of fixing the wire harness. However, the structure uses a rubber sleeve clamping method when fixing the wire harness. , in actual application, it does not play its due role in fixing the wire harness, especially when the pulling force is too large, there is still a risk of falling off
