The invention provides an insulating cap with a pressure sensor, which mainly solves the problem that the connection between the existing insulating cap and the outer cone bushing is not close enough and easy to crack, and the staff can only judge the connection degree by experience, which is poor in reliability, complex in structure and high in cost. The insulating cap includes a shielding sleeve fixed in the insulating layer, which is vulcanized into an integral part. The inner wall of the insulating layer is fitted with the outer cone sleeve for clamping and preventing the groove from escaping. The groove is set at 10-20 mm from the opening end of the outer chasing insulating cap. A pressure sensor is arranged on the inner wall of the insulating layer and a display device is arranged on the outer wall of the insulating layer. A display device for the pressure on the inner wall of the insulating layer, and a pressure sensor are connected with the display device. The insulation cap has a high reliability and simple structure, because it adopts the clamping connection mode, which greatly improves the connection strength and can not be removed from the outer cone bushing in the bad use process.

带压力传感器的绝缘帽
本专利技术涉及一种绝缘帽。
技术介绍
现有绝缘帽一般直接套接在外锥套管上,由于外锥套管表面光洁度较高,且存在一定锥度,在安装到位卸去外力后,绝缘帽可能从外锥套管上向外滑动,从而导致两者之间接触不紧密,出现缝隙,影响二者之间的绝缘配合。为了解决这一技术问题,本领域技术人员采用将绝缘帽内的屏蔽套加工为螺纹形状,通过螺纹连接保证两者之间的连接强度,现有的屏蔽套为两种结构形式,一种采用金属加工成型,而金属屏蔽套与橡胶绝缘套之间的连接强度较低,这样在安装时,径向作用力容易导致屏蔽套和绝缘帽之间撕裂,从而无法安装;另一种采用导电橡胶,导电橡胶虽然解决了安装过程中屏蔽套和外追绝缘帽之间易撕裂的问题,但该结构形式较为复杂且螺纹状屏蔽套加工也较为困难;同时,螺纹连接的方式可能由于震动等原因导致连接松动,从而导致了安全事故的产生。
