Abstract
A high voltage outlet structure of an ultra-high voltage shunt reactor comprises a voltage sharing pipe (1) and a voltage sharing ball (2) connected to the tail end of the voltage sharing pipe. The high voltage outlet structure of an ultra-high voltage shunt reactor further comprises an insulating paper cylinder (3) on the outer side of the voltage sharing ball, a Ω-type paperboard (4) on the outer side of the insulating paper cylinder, and a lead supporting structure (5). Three layers of insulating paper pulp (2a) and two layers of supporting strips (2b) are disposed on the outer side of the voltage sharing ball at intervals. The insulating paper cylinder is mounted below an ascending seat (8), and an opening (19) is provided below the insulating paper cylinder. Two ends of the Ω-type paperboard are fixed to a tank wall of an oil tank (12). The lead supporting structure clamps the voltage sharing pipe by arranging grooving paperboards (5a) in a staggered mode. A thick paperboard (5b) configured to fix the grooving paperboards is disposed below the grooving paperboards. The lower part of the thick paperboard is supported by an insulating conductor grip (5c). The high voltage outlet structure of an ultra-high voltage shunt reactor guarantees electrical strength and reliable insulation of outlet of 1100 kilovolts, and also guarantees mounting of the outlet structure and a sleeve on an oil tank body, thereby avoiding shearing action of a high voltage ascending seat on the oil tank body, improving the shock resistance of the ultra-high voltage shunt reactor, and guaranteeing long-term safe running of the reactor.
Description
技术领域 Technical field
本发明涉及一种电抗器出线结构，具体涉及一种特高压并联电抗器高压出线结构。 The invention relates to a reactor outlet structure, in particular to a high voltage outlet reactor of a high voltage shunt reactor.
背景技术 Background technique
1100千伏特高压并联电抗器高压出线一般采用间接出线结构。即高压出线进入由绝缘件、铜管、均压球等组成的出线装置，然后与套管接线板连接。出线装置与套管安装在独立于油箱外的“象鼻型”升高座中，整个升高座重量大约为16吨。由于电抗器本体作为震源振动极大，高压“象鼻型”升高座独立于本体油箱外部，对油箱产生极大的剪切作用。在100Hz频率的电抗器本体振动下，独立的'象鼻型'升高座产生很大的安全隐患；同时，由于本体与升高座重量相差不大，二者仅靠法兰与加强铁连接，抗震能力较差。
The high-voltage outlet of the 1100 kV UHV shunt reactor generally adopts an indirect outlet structure. That is, the high-voltage outlet enters the outlet device composed of an insulating member, a copper tube, a pressure equalizing ball, and the like, and then is connected to the casing wiring board. The outlet device and casing are installed in a "nose-like" raised seat that is independent of the fuel tank. The entire raised seat weighs approximately 16 tons. Since the reactor body vibrates as a source, the high-pressure "nose-like" raised seat is independent of the outside of the body tank, causing a great shearing effect on the tank. Under the vibration of the reactor body of 100Hz frequency, the independent 'nose-type' elevated seat creates a great safety hazard; at the same time, because the weight of the main body and the raised seat are not much different, the two are only connected to the reinforcing iron by the flange, and the earthquake is resistant. Poor ability.
