One, two or three devices of a cabinet lighting lamp, an electromagnetic lock and an electrified display device are generally arranged on a door of an electrified compartment of the switch cabinet. The electrified display device is used for detecting whether the bus in the switch cabinet is electrified or not, and is indicated by the indicator lamp, and simultaneously, a locking or unlocking signal is sent out, so that the electromagnet in the electromagnetic lock is powered off or is powered on, and the purposes that the cabinet door can not be unlocked and opened or the cabinet door can be unlocked and opened are achieved.
Currently, the national grid company, the power plant and the large-scale power consumer all require that the switch cabinet have the performance of preventing the internal arc from escaping (namely, anti-arcing) so as to protect the personal safety of operation maintenance personnel. In addition, the national power grid company greatly pushes the standardized design of the switch cabinet so as to facilitate large-scale centralized purchasing, manufacturing, later operation and maintenance, replacement of spare parts and the like.
The disadvantages of the current market products are:
1. the three devices are three independent devices, the size and the installation mode of the installation opening are different, the device configuration requirement of each project is different, and the three devices are combined in 6 different ways, so that the cabinet door with 6 different openings is required for the switch cabinet with each specification, the standardization degree is low, the installation wiring efficiency is low, and mistakes are easy to occur.
2. At present, the illumination lamps in cabinets except for some factories adopt a metal sealing structure and have an anti-arcing function, and the electromagnetic locks and the electrified display devices are also mostly plastic shell structures and do not have the anti-arcing function.
3. The existing electromagnetic lock can only retract or extend the lock tongue through manual pulling buttons or rotating handles, so that the purposes of opening and locking the door are achieved, the lock tongue cannot retract or pop out automatically, and the lock tongue is closed when in an extending state, so that the lock rod is damaged.
