On-line monitoring system for safety performance of power device

Abstract

The invention relates to an on-line monitoring system for the safety performance of a power device. The device comprises a rack and a controller, a first insulated wire is arranged on the rack, and acounterweight assembly for applying tension to the first insulated wire is arranged on the rack. A puncture wire clamp is arranged on the first insulated wire, a pressure sensor is arranged on the puncture wire clamp, and a wind speed sensor and a temperature sensor are further arranged on the rack. The device has the advantages that the counterweight assembly is arranged on the first insulated wire, and the tension values of the first insulated wire in different states can be simulated in real time only by adjusting the weight of the counterweight assembly, so that the pressing force of the puncture wire clamp on the first insulated wire can be collected in real time through the pressure sensor; the wind speed sensor and the temperature sensor are used for collecting the wind speed and temperature conditions around the rack in real time, an operator can visually obtain the change of the pressing force of the puncture wire clamp on the first insulated wire in different temperature environments, different wind speeds and different tension environments, so that the safety performance of the power device is ensured.

Description

technical field [0001] The invention relates to an online monitoring system for the safety performance of electric equipment. Background technique [0002] The insulation puncture clamp is mainly composed of a reinforced shell, a puncture blade, a gasket, a waterproof silicone grease, a high-strength bolt, a torque nut and a cable terminal cap. When the cable needs to be branched or connected, the cable branch line terminal is inserted into the waterproof terminal. Cap cover, after determining the branch position of the main line, use a socket wrench to twist the torque nut on the clamp. During the process, the contact blade will pierce the cable insulation layer and contact with the conductor. Silicone grease overflows. When the torque reaches the set value, the nut torque mechanism falls off, the main line and the branch line are connected, and the waterproof performance and electrical effect have reached the parameters required by the standard. However, after the existing...

[0002] The insulation puncture clamp is mainly composed of a reinforced shell, a puncture blade, a gasket, a waterproof silicone grease, a high-strength bolt, a torque nut and a cable terminal cap. When the cable needs to be branched or connected, the cable branch line terminal is inserted into the waterproof terminal. Cap cover, after determining the branch position of the main line, use a socket wrench to twist the torque nut on the clamp. During the process, the contact blade will pierce the cable insulation layer and contact with the conductor. Silicone grease overflows. When the torque reaches the set value, the nut torque mechanism falls off, the main line and the branch line are connected, and the waterproof performance and electrical effect have reached the parameters required by the standard. However, after the existing insulation piercing wire clip is installed, due to the cable Affected by different environments, such as changes in wind speed, tension, and temperature, if the cable puncture clip is too shallow or too deep, it will affect the safety of the clamp connection. If the puncture is too shallow, the contact resistance will increase, which will easily cause the clamp The heat at the connection will cause a fire if it is serious; if the puncture is too deep, the inner wire of the cable will be damaged and broken, which will affect its mechanical strength and safety.
