Post.
The utility model is further improved, and described casing sets chamber door, and box frame upper door frame sets backstop, when chamber door is closed
With box frame level；Described chamber door is flexibly connected with casing, if lockset.
The utility model is further improved, and connection through hole, described connection through hole and bolt, expansion are set in described casing
Bolt or fixed support coordinate fixes casing.
When using, casing side wiring hole, its heart yearn is passed through to correspond to be connected to busbar I, the and of busbar II respectively on extension cable
On busbar III, cable shield ground wire is connected on cable shield earth terminal；The connection busbar in casing opposite side cable connection hole
It is connected on busbar I, busbar II and busbar III using heart yearn is corresponding respectively with extension cable one end, cable shield ground wire is connected to cable
On shielding earth binding post, the extension cable other end is connected with momentary switch cabinet.
Compared with prior art, the utility model has the advantages that simple structure, easy to use, safe and reliable, temporary cable
It is not required to be modified former cable termination during switching, quick, convenient extension cable length thoroughly solves electric substation's transformation interim
The inadequate problem of cable length in load transition process, saves resettlement load power off time, improves operating efficiency.
