Description

Operation mode locking module of automatic transfer switch device

Technical Field

The utility model belongs to the technical field of low-voltage apparatus, specifically say so and relate to an automatic change over switch device's mode of operation locking module.

Background

Along with the development of society, the requirements of people on a power grid and the power grid in the power transmission and distribution process are gradually improved, and in some important power distribution occasions, a power supply system is required to ensure the continuity, so that the power utilization safety and the production life are not interrupted; the automatic change-over switch is provided with two or more groups of mutually independent contact systems, and can respectively control the connection/disconnection of a main power supply and a standby power supply which are connected with the automatic change-over switch under the action of the controller, so that the power transmission and distribution line is changed between the main power supply and the standby power supply; automatic transfer switches are therefore widely used in this field.

The existing automatic change-over switch is generally provided with a switching device between an automatic position, a manual position and a padlock position, an operator only needs to operate an indicating piece arranged on a panel to operate under a corresponding mode, when the indicating piece is displayed at the automatic position, the controller controls the switching-on and switching-off operation of the switch at the moment, the operator cannot perform the switching-on and switching-off operation of the switch through tools such as a handle and the like, and meanwhile, a padlock plate cannot be pulled out to perform the padlock, when the indicating piece is displayed at the manual position, the controller needs to quit the control at the moment, the operator can insert the tools such as the handle and the like into an operation hole of an operating mechanism to perform the operation, the padlock plate cannot be pulled out to perform the padlock at the moment, when the indicating piece is displayed at the padlock position, the controller needs to quit the control at the moment, and simultaneously, the operator cannot perform the switching-on and switching-off operation of the switch through the tools such as the handle and the like, and the padlock plate can be pulled out of the padlock plate. In some operation scenes, if a fault occurs, when maintenance is needed, in order to ensure the safety of operators, the padlock plate can be pulled out for padlock only when the padlock plate is in a double-division position. However, the above-described conventional structure has the following drawbacks: 1) The operation button on the panel is small, but the operation force value is large, and large operation force is needed; 2) The hand-operated handle is generally placed on the side surface of the switch or separated from the switch, so that the phenomenon that the handle cannot be found or is missed when leaving a factory is easy to occur during field operation; 3) The three position states of the automatic, manual and padlock are not related, so that the operation of another state is easily carried out in one position state, and safety accidents are caused.

Chinese patent 201710833952.5 discloses a switching device for a switch, comprising: a handle including a first slot; a mode button operable to change an operation mode of the switch, the mode button including a second slot; a slider connected with the mode button and movable in a first direction in association with movement of the mode button, the slider including a first block; a lever operable to rotatably open and including a pin, wherein the first block is received in the first slot to retain the handle when the mode button is disposed in the service position, and the pin is operable to pass through the second slot to prevent movement of the mode button in response to the lever being rotatably opened. It is achieved that both electrical and manual operation is disabled by the locking mechanism when the switch is operated in the service mode, also referred to as padlock mode. However, the technical scheme provided by the patent mainly utilizes an electrical system to realize three position states of automatic, manual and padlock of the automatic transfer switch device, and the padlock can be used at any position and has lower reliability.
