Background
When a 10kV switch cabinet is in power failure maintenance, a fixed contact on the line side or the bus side behind a separation baffle in the switch cabinet is often electrified. Therefore, it is required to reliably close the isolation barrier to prevent a person from accidentally opening the isolation barrier to touch the charged site. And the anti-false-entry function of the static contact of the currently used 10kV switch cabinet has a common leak. Although the isolation baffle capable of shielding the electrified static contact is installed in the switch cabinet, no locking device is designed, and after the switch handcart is pulled out, the isolation baffle linkage mechanism is directly exposed in the space of the cabinet body, and the isolation baffle can be conveniently opened by one person. The current anti-false-entry measures are as follows: after the handcart switch in the maintenance state is pulled out, the mechanical lock is additionally arranged on the isolation baffle and the running red flag is hung, but the isolation baffle transmission mechanisms of different switch cabinets are different, the mechanical lock is time-consuming and labor-consuming to additionally arrange, and the mechanical lock cannot be additionally arranged in the position of a padlock which is not designed in some switch cabinets. At the moment, only the 'operation' red flag can be hung, the safety monitoring is enhanced, the key safety is in the end, a specially responsible guardian is appointed if necessary, and once the guardian and the maintainer carelessly neglect the carelessness, danger can occur.

Detailed Description
The following further describes embodiments of the present application with reference to the drawings.
As shown in fig. 1-2, the simple locking device of the static contact isolation baffle of the 10kV switch cabinet related to the application comprises a first connecting rod 1 and a second connecting rod 2 which are L-shaped, a threaded hole is formed in a cross rod 3 of the first connecting rod, a through hole penetrating through the cross rod is formed in a cross rod 5 of the second connecting rod, a screw rod 7 is inserted into the cross rod 5 of the second connecting rod along the through hole, the screw rod 7 can only rotate relative to the cross rod 5 of the second connecting rod and cannot generate displacement, one end of the screw rod 7 is connected with an adjusting knob 8, the other end of the screw rod 7 is exposed outside the cross rod 5 of the second connecting rod, the screw rod 7 is matched with the threaded hole for use, and the distance between a vertical rod 4 of the first connecting rod and a vertical rod 6 of the second connecting rod is adjusted through the matching of the screw rod 7 and the threaded hole.
