在上述的隔震支座中，支座主体的第一支撑台用于与变压器主体的底部连接，支座主体的第二支撑台用于与风机机舱连接，当变压器主体以及风机机舱发生震动时，与变压器主体连接的第一支撑台会随着变压器主体发生相应的震动，与风机机舱连接的第二支撑台会随着风机机舱发生相应的震动，从而第一支撑台与第二支撑台之间会由于震动产生一定的震动位 移。由于拉杆的第一端与第一支撑台连接，阻尼件的第四端与第二支撑台连接，则当变压器主体与风机机舱发生震动时，拉杆会随着第一支撑台的震动而发生相应的震动，阻尼件会随着第二支撑台的震动而发生相应的震动，从而拉杆与阻尼件之间会由于震动产生一定的震动位移。又由于限位件能够限制拉杆的第二端与阻尼件的第三端的距离，则限位件能够限制拉杆与阻尼件之间的距离，从而限制拉杆与阻尼件之间所产生的震动位移的范围，以此来限制第一支撑台与第二支撑台之间由于震动所产生的震动位移，进一步地削弱变压器主体的震动。
另外，当拉杆的第二端与阻尼件的第三端之间的距离超过预设距离时，此时阻尼件能够被触发，当阻尼件被触发后，阻尼件能够增加上述的隔震支座的阻尼，从而能够更好的限制第一支撑台与第二支撑台之间由于震动所产生的震动位移，并且能够让上述的隔震支座具有更好的抗震动能力，进一步地能够实现更好的隔震效果，降低上述的变压器的震动响应，使得上述的变压器不容易发生损坏。

如图1至图5所示，一实施例所涉及的隔震支座，包括：支座主体100以及阻尼组件200。
具体地，支座主体100具有第一支撑台110以及与第一支撑台110并列且间隔设置的第二支撑台120；阻尼组件200包括拉杆210、限位件220以及阻尼件230，拉杆210具有第一端211以及第二端212，第一端211与第一支撑台110连接，阻尼件230具有第三端231以及第四端232，第四端232与第二支撑台120连接，第三端231与第二端212相对且间隔设置，限位件220的一端与第二端212连接，限位件220的另一端用于供第三端231可活动地穿设进限位件220内；其中，限位件220用于限制第二端212与第三端231之间的距离，在第二端212与第三端231之间的距离超过预设距离的情况下，阻尼件230能够被触发。
在上述的隔震支座中，支座主体100的第一支撑台110用于与变压器主体的底部连接，支座主体100的第二支撑台120用于与风机机舱连接，当变压器主体以及风机机舱发生震动时，与变压器主体连接的第一支撑台110会随着变压器主体发生相应的震动，与风机机舱连接的第二支撑台120会随着风机机舱发生相应的震动，从而第一支撑台110与第二支撑台120之间会由于震动产生一定的震动位移。由于拉杆210的第一端211与第一支撑台110连接，阻尼件230的第四端232与第二支撑台120连接，则当变压器主体与风机机舱发生震动时，拉杆210会随着第一支撑台110的震动而发生相应的震动，阻尼件230会随着第二支撑台120的震动而发生相应的震动，从而拉杆210与阻尼件230之间会由于震动产生一定的震动位移。又由于限位件220能够限制拉杆210的第二端212与阻尼件230的第三端231的距离，则限位件220能够限制拉杆210与阻尼件230之间的距离，从而限制拉杆210与阻尼件230之间所产生的震动位移的范围，以此来限制第一支撑台110与第二支撑台120之间由于震动所产生的震动位移，进一步地削弱变压器主体的震动。
另外，当拉杆210的第二端212与阻尼件230的第三端231之间的距离超过预设距离时，此时阻尼件230能够被触发，当阻尼件230被触发后，阻尼件230能够增加上述的隔震支座的阻尼，从而能够更好的限制第一支撑台110与第二支撑台120之间由于震动所产生的震动位移，并且能够让上述的隔震支座具有更好的抗震动能力，进一步地能够实现更好的隔震效果，降低上述的变压器的震动响应，使得上述的变压器不容易发生损坏。
如图1至图3所示，在其中的一个实施例中，限位件220为限位套筒，限位套筒的一端与第二端212固定连接，限位套筒的另一端用于供第三端231可活动地穿设进限位套筒内。
如此，当阻尼件230的第三端231从限位套筒远离第二端212的一端穿设进限位套筒内时，限位套筒能够限制第三端231远离第二端212的距离，则限位套筒能够限制拉杆210与阻尼件230之间的距离，从而限制拉杆210与阻尼件230之间所产生的震动位移的范围，以此来限制第一支撑台110与第二支撑台120之间由于震动所产生的震动位移，进一步地削弱变压器主体的震动。
如图1至图4所示，在其中的一个实施例中，限位套筒的侧壁上开设有限位槽221，限位槽221沿限位套筒的轴向延伸，第三端231具有限位部2311，限位部2311能够从限位套筒远离第二端212的一端穿设进限位套筒内，并置于限位槽221内，且限位部2311在限位槽221内滑动；其中，在第二端212与限位部2311之间的距离超过预设距离的情况下，阻尼件230能够被触发。
具体地，限位部2311沿限位套筒的径向凸出于第三端231，且限位部2311可活动地穿设于限位槽221内。
进一步地，在限位部2311位于限位槽221远离第二端212的一端情况下，若限位部2311继续朝着远离第二端212的方向运动，此时，第二端212与限位部2311之间的距离超过预设距离。
如此，当阻尼件230的限位部2311穿设于限位套筒内时，限位槽221能够限制限位部2311在限位套筒内的移动范围，从而能够限制第三端231与第二端212之间的距离，进一步地能够限制拉杆210与阻尼件230之间所产生的震动位移的范围，以此来限制第一支撑台110与第二支撑台120之间由于震动所产生的震动位移，从而削弱变压器主体的震动。由于限位槽221沿限位套筒的轴向延伸，则限位部2311能够在限位槽221内沿限位件220的轴向滑动，在限位部2311在限位槽221远离第二端212的一端情况下，若限位部2311继续朝着远离第二端212的方向运动以超过预设距离，此时，阻尼件230能够被触发，则被触发之后的阻尼件230能够增加上述的隔震支座的阻尼，从而能够更好的限制第一支撑台110与第二支撑台 120之间由于震动所产生的震动位移，并且能够让上述的隔震支座具有更好的抗震动能力，进一步地能够实现更好的隔震效果，降低上述的变压器的震动响应，使得上述的变压器不容易发生损坏。
另外，限位槽221还能够给第三端231提供一定的位移范围，从而能够削弱上述的隔震支座的刚度，使得上述的隔震支座具有更好的减震效果。
如图3至图5所示，在其中的一个实施例中，限位槽221有两个，两个限位槽221并列且间隔设置，限位部2311的两端分别在两个限位槽221内滑动。
如此，两个并列且间隔设置的限位槽221能够给限位部2311起到更好的限制作用，同时使得限位部2311在限位槽221内滑动时能够具有更强的结构稳定性。
如图1、图2所示，在其中的一个实施例中，支座主体100还包括支撑柱130，支撑柱130的一端与第一支撑台110连接，支撑柱130的另一端与第二支撑台120连接，阻尼组件200有多个，多个阻尼组件200并列且间隔设置在第一支撑台110与第二支撑台120之间，且多个阻尼组件200围设在支撑柱130的周围。
具体地，在其中的一个实施例中，每个阻尼组件200的限位件220上所开设的限位槽221的长度各不相同(未示出)，从而能够防止所有阻尼组件200的拉杆210与阻尼件230同时超过预设距离，避免由于多个阻尼组件200的拉杆210与阻尼件230同时超过预设距离而导致上述的隔震支座刚度太大，从而造成的冲击使得拉杆210被损坏。
更具体地，可根据实际的工况选择阻尼组件200的个数以及每个阻尼组件200的限位件220上所开设的限位槽221的长度。
由于支撑柱130的一端与第一支撑台110连接，支撑柱130的另一端与第二支撑台120连接，则支撑柱130能够进一步地限制第一支撑台110与第二支撑台120之间所产生的震动位移。又由于多个阻尼组件200并列且间隔围设在支撑柱130的周围，则多个阻尼组件200能够进一步地限制第一支撑台110与第二支撑台120之间所产生的震动位移，从而削弱变压器主体的震动。同时，当多个阻尼组件200中的多个阻尼件230被触发时，多个阻尼件230能够叠加地增加上述的隔震支座的阻尼，从而能够让上述的隔震支座具有更好的抗震动能力，进一步地能够实现更好的隔震效果，降低上述的变压器的震动响应，使得上述的变压器不容易发生损坏。
如图1、图2所示，在其中的一个实施例中，第一端211连接在第一支撑台110靠近第二支撑台120的一面上，且第一端211与第一支撑台110转动连接。
由于第一端211与第一支撑台110转动连接，则当第一支撑台110由于变压器主体的震 动而发生水平位移时，拉杆210不会因为第一支撑台110的位移而在第一端211处发生断裂，从而使得上述的隔震支座能够较大的水平变形，进一步地能够使得上述的隔震支座具有更强的结构稳定性，能够为上述的变压器提供给更好的隔震作用。
如图1、图2所示，在其中的一个实施例中，隔震支座还包括第一连接座300，第一连接座300固定连接在第一支撑台110靠近第二支撑台120的一面上，第一端211与第一连接座300铰接。
由于第一连接座300固定连接在第一支撑台110靠近第二支撑台120的一面上，第一端211与第一连接座300铰接，则当第一支撑台110由于变压器主体的震动而发生水平位移时，拉杆210能够相对于第一连接座300转动，从而使得拉杆210能够相对于第一支撑台110转动。如此，拉杆210不会因为第一支撑台110的位移而在第一端211处发生断裂，使得上述的隔震支座能够较大的水平变形，进一步地能够使得上述的隔震支座具有更强的结构稳定性，能够为上述的变压器提供给更好的隔震作用。
如图1、图2所示，在其中的一个实施例中，第四端232连接在第二支撑台120靠近第一支撑台110的一面上，且第四端232与第二支撑台120转动连接。
由于第四端232与第二支撑台120转动连接，则当第二支撑台120由于风机机舱的震动而发生水平位移时，拉杆210不会因为第二支撑台120的位移而在第四端232处发生断裂，从而使得上述的隔震支座能够较大的水平变形，进一步地能够使得上述的隔震支座具有更强的结构稳定性，能够为上述的变压器提供给更好的隔震作用。
如图1、图2所示，在其中的一个实施例中，隔震支座还包括第二连接座400，第二连接座400固定连接在第二支撑台120靠近第一支撑台110的一面上，第四端232与第二连接座400铰接。
由于第二连接座400固定连接在第二支撑台120靠近第一支撑台110的一面上，第四端232与第二连接座400铰接，则当第二支撑台120由于风机机舱的震动而发生水平位移时，拉杆210能够相对于第二连接座400转动，从而使得拉杆210能够相对于第二支撑台120转动。如此，拉杆210不会因为第二支撑台120的位移而在第四端232处发生断裂，使得上述的隔震支座能够较大的水平变形，进一步地能够使得上述的隔震支座具有更强的结构稳定性，能够为上述的变压器提供给更好的隔震作用。
一实施例所涉及的变压器，包括：变压器主体以及如上述所述的隔震支座。
具体地，隔震支座的第一支撑台110远离第二支撑台120的一面与变压器主体的底部连接。
在上述的变压器中，由于上述的隔震支座的第一支撑台110远离第二支撑台120的一面与变压器的底部连接，因此上述的隔震支座能够给上述的变压器提供隔震作用。又由于上述的隔震支座能够给上述的变压器提供较好的隔震效果，因此上述的变压器能够具有较好的抗震动能力，从而上述的变压器不容易发生损坏。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
