Description
Technical Field
The utility model relates to an electrical equipment safety technical field, in particular to cubical switchboard generating line storehouse is prevented mistake and is opened locking device.
Background
The high-voltage switch cabinet is an electrical device, is used for switching on and off, controlling or protecting and the like in power generation, power transmission, power distribution, electric energy conversion and consumption of an electric power system, and is required to have a five-prevention function: the circuit breaker is prevented from being switched on by mistake, the isolating switch (or a handcart contact) is prevented from being switched on by load, the grounding wire (a grounding switch) is prevented from being hung in a charged state, the grounding wire (a grounding knife switch) is prevented from being switched on and power is supplied, and the circuit breaker is prevented from being switched into a charged interval by mistake. The function of preventing mistakenly entering into the electrified space of the existing switch cabinet mostly refers to the following two functions: 1) after the circuit breaker handcart is pulled out, a handcart room valve is automatically closed, and a high-voltage electrified part is isolated; 2) and the mechanical interlocking of the grounding switch and the door plate of the cable chamber is realized. When the line side is electroless and the handcart is in the test position, the grounding switch is closed, the hook on the door plate is unlocked, and the door plate of the cable chamber can be opened at the moment. However, when the cabinet top works, no related mechanical locking or electrical locking device exists, and when a maintainer opens the bus bar bin above the cabinet top to work, no related live indication can be referred to.
Among the prior art, in order to avoid carrying out the bus bar storehouse during operation at the cabinet top, the maintainer is opened the electrified interval by mistake and is aroused the casualties accident of electrocution, generally before the maintenance work is started, set up at the cabinet top and block, keep apart electrified part and maintenance part, whether open bus bar storehouse interval electrified through the place ahead panel is confirmed to cooperation personnel through the below, the method that the dependence set up at the cabinet top and block guarantees the safety of operation personnel, however, this prior art still can't satisfy the cubical switchboard and prevent mistake income electrified spaced requirement. When the bus of the switch cabinet is powered off, once operation or maintenance personnel are not familiar with the wiring of the on-site switch cabinet, the barrier is put in a wrong position, and the caused consequence can be imagined. The transparent observation window is not arranged at the rear upper part of some switch cabinets, the bus trend at the positions of the sectional switch cabinet and the isolation switch cabinet is difficult to confirm on site, the barrier can be set only by experience, and the barrier can also be set wrongly. When the maintenance is carried out, inexperienced maintenance personnel mistakenly move the obscuration/forget the recovery, and the mistaken entering of the electrified interval is also possible. The safety barrier is only set manually, so that the method has great limitation. Once the personnel confirm the mistake or communicate the information and have the mistake, the cabinet top staff can open electrified interval bus storehouse by mistake to lead to the maintainer to electrocute the casualty, cause serious consequence. Therefore, there is a need for a locking device for preventing the bus bar compartment of the switch cabinet from being opened by mistake to solve the above problems.
