Adsorbent replacement device and high-voltage switchgear

The invention discloses an adsorbent replacing device. The adsorbent replacing device comprises an adsorbent shell and an external connecting part, the adsorbent shell penetrates through the high-voltage switch air chamber, the adsorbent shell is provided with an adsorbent shell channel, the adsorbent shell channel extends out of the high-voltage switch air chamber, a plug is plugged in the adsorbent shell channel, and the plug can be opened; the pressure in the external connection part is equal to the pressure in the adsorbent shell, and the external connection part can be communicated with the adsorbent shell channel. When the adsorbent is replaced, the external connecting part is firstly communicated with the adsorbent shell, and the old adsorbent is recycled. And then the external connection equipment filled with the new adsorbent is conducted with the adsorbent shell, so that replacement of the adsorbent is completed. According to the invention, the adsorbent can be replaced under the condition that the
