The difference and application of touchable and non-touchable inductive electrification
The key difference between inductive electricity-activated touchable cable terminal head and inductive electricity-activated non-touchable cable terminal head is that the silicon rubber cable connection head has a semiconductor material shielding layer inside, and a conductive shielding layer outside, and the grounding device is connected according to the financial collar to ensure that the potential difference on the surface surface of the cable terminal head is the same as that of the grounding device. The latter is the same as the silicone rubber cable connector, and according to the evaluation results, the working voltage of both to the ground is zero, but in the specific operation, the latter surface will cause magnetic induction electrostatic induction.
If the application is in the side-by-side operation of multiple control loops inside a substation, it is necessary to verify that the application of the touchable cable terminal is beneficial for safety when the primary circuit and the adjacent control loop are activated. However, the application in the cable branch box, there will be no such problems, because the design scheme is maintenance-free maintenance goods, there is no secondary route in the branch box must be maintained and repaired, and the branch box shell is IP33 waterproof grade, the shell has relied on the ground device, it is not allowed to open the branch box shell during the induction power operation. Anything that does not have inductive electrical contact with the cable terminal inside the support box will.
Even in the case of damage that is not resistant to external forces (such as being obviously collided by external factors such as a car), the application of touchable and non-touchable cable terminators, the results are the same. Analyzed from the perspective of reliability in operation, the touchable cable end head has no outer insulation layer because the surface covers the conductive layer and is grounded by the metal material hoop. The surface layer of the non-touchable cable terminal is a strong insulating layer of silicone, and there are many external insulation layers.
Obviously, under the same conditions, the operation credibility of the non-touchable cable terminal is higher than that of the touchable cable terminal. From the perspective of economic development, the price of non-touchable silicone rubber cable connectors is also less than that of touchable cable terminals. Therefore, it is ideal to choose non-touchable silicone rubber cable connectors.
