An online monitoring system for the safety performance of electrical equipment

Abstract

The invention relates to an online monitoring system for the safety performance of electrical equipment, which includes a frame and a controller. The frame is provided with a first insulated wire, and the frame is provided with a counterweight assembly for applying tension to the first insulated wire. The wire is provided with a puncture wire clip, the puncture wire clip is provided with a pressure sensor, and the frame is also provided with a wind speed sensor and a temperature sensor; the advantage of the present invention is that the counterweight assembly is provided on the first insulated wire, and only by adjusting The weight of the counterweight component is used to simulate the tension value of the first insulated wire in different states in real time, and the pressing force of the puncture wire clip on the first insulated wire can be collected in real time through the pressure sensor, and the real-time collection can be made through the wind speed sensor and temperature sensor. According to the wind speed and temperature around the rack, the operator can intuitively obtain the change of the pressing force of the puncture wire clip on the first insulated wire under different temperature environments, different wind speeds, and different tension environments, so as to ensure the safety performance of electrical equipment .

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.
