Embodiment
Traveling one is entered to the installation method of double line vacuum circuit breaker net side cabinets and its high voltage electric equipment below in conjunction with the accompanying drawings Walk explanation.
This net side cabinet of double line vacuum circuit breakers 4, the lower section of cabinet are provided with dodge gate and drop front, set inside dodge gate There is connector 8, walking beam 1 is fastened by bolts the top rear installed in net side cabinet framework 2, and arrester 3 is fixed on net in cabinet Below sidecar on chassis, a line vacuum circuit breaker 4, vacuum are each side installed with centered on arrester in cabinet 3 The front of main circuit breaker 4 is provided with high voltage ground switch 9, installs high tension voltage respectively on side wall and rear cross beam above the net side cabinet Transformer 5 and supporting insulator 6,5 outgoing line sides of high voltage potential transformer are connected with line vacuum circuit breaker 4, and mounting seat is fixed On the madial wall of the side wall of net side cabinet framework 2, supporting insulator 6 is fixedly mounted on cabinet rear cross beam, positioned at vacuum master The top of breaker 4.Safety interlocking key locker 7 is installed with the lateral wall of net side cabinet side wall.The side wall of net side cabinet framework 2 Left and right sidewall cutting is sloping.
The installation method of double net side cabinet high voltage electric equipments of line vacuum circuit breaker 4, step are as follows:Net side cabinet will be arranged on The installation bolt of the walking beam 1 of the top rear of framework 2 unloads, and pulls down walking beam 1;
1. the mounting bracket of line vacuum circuit breaker and high voltage ground switch is lifted in network access sidecar, net side bottom of cabinet frame is fixed on On;
2. first the lifting of high voltage ground switch 9 is put into the mounting bracket of net side cabinet line vacuum circuit breaker and high voltage ground switch It is fixed, then two line vacuum circuit breakers 4 are lifted to the peace for being put into net side cabinet line vacuum circuit breaker and high voltage ground switch respectively Interior fixation is shelved, arrester 3 in cabinet is then being fixedly mounted below net side cabinet on chassis.Centered on arrester in cabinet 3, two Side respectively one line vacuum circuit breaker 4 of installation, the installation high voltage ground switch 9 in front of line vacuum circuit breaker 4, and high-voltage earthing is opened Close arrester 3 and line vacuum circuit breaker 4 in 9, cabinet and be located at same layer;
3. the mounting seat of high voltage potential transformer 5 is fixedly mounted on the madial wall of net side cabinet side wall, high tension voltage is mutual Outgoing line side of sensor 5 is connected with the upper end of line vacuum circuit breaker 4.
4. supporting insulator 6 is arranged on cabinet rear cross beam, above line vacuum circuit breaker 4, and supporting insulator 6 It is located at same layer with high voltage potential transformer 5.
Mainly there are line vacuum circuit breaker 4, high voltage ground switch 9, arrester 3, high tension voltage in cabinet in double main suspension sidecars The equipment such as mutual inductance and supporting insulator 6, wherein line vacuum circuit breaker 4, high voltage ground switch 9, high voltage potential transformer 5 and In order to ensure the requirement of the installation accuracy of the high voltage ground switch 9 of two line vacuum circuit breakers 4 and matching double transmission mechanisms And the mounting bracket configured, the quality and volume of above electrical equipment component are all larger, it is necessary to be lifted from net side cabinet top open part Network access sidecar is installed.
In order to ensure that the electrical equipment of big quality large volume in net side cabinet can be installed smoothly, by net side cabinet top rear Fig. 1, figure are shown in the detachable walking beam that crossbeam 1 is changed to be installed with fastening bolt from the mode of being welded and fixed, the signal of walking beam position 2.Considering net side cabinet back side top needs external high-tension cable, and in order to avoid cabinet and locomotive side wall crossbeam and wire casing Connect needs to cut sloping processing above mill problem, net side cabinet cabinet or so side wall, sees Fig. 1.
During net side cabinet assembles, first walking beam is disassembled, then line vacuum circuit breaker 4 and high-voltage earthing are opened Close and fastened in 9 mounting bracket lifting network access sidecar, though mounting bracket volume is big, quality is relatively light, to net side bottom of cabinet frame Pressure is more dispersed, and influenceing very little to the net side cabinet cabinet body structure for walking beam of dismantling can ignore, hereafter can be by walking beam weight New installation is fastened to ensure that cabinet body structure is indeformable.
Finally, after walking beam installs, using arranged in cabinet from top to bottom, vertical order, lifting is high successively Press the electrical equipments such as earthed switch 9, line vacuum circuit breaker 4, high voltage potential transformer 5.
Arrester 3 in cabinet, the electrical equipment such as support insulator and safety interlocking key locker 7 quality and volume be relatively in cabinet It is small, it can directly be installed manually by installation personnel after above electrical equipment installs.
