Abstract
The utility model relates to a switch cabinet which is used for a substation in a power system, specifically an intelligent-type locking device for a switch cabinet. The device comprises a cabinet body with a cabinet door, an electromagnet, a T-shaped hook, and an L-shaped fixed plate. The device is characterized in that the electromagnet is provided with a central hole; the interior of the central hole is provided with a limiting rod; a side of the fixed plate is connected with the cabinet door; the electromagnet is fixed at the other side of the fixed plate; the T-shaped hook is corresponding to the limiting rod and fixed on the cabinet door at a side of the cabinet door; a wire of the electromagnet is connected with a ground line in the cabinet body; when a ground apparatus in the cabinet is closed or a circuit breaker is located at a testing position, the electromagnet is electrified, a limiting rod is sucked, the hook loses obstruction, and therefore, the cabinet door can be opened; when the round apparatus in the cabinet is opened or the circuit breaker is not located at the testing position, the latching electromagnet loses electricity, the limiting rod falls to block the hook, and therefore, the cabinet door cannot be opened; the device is simple in installation, is convenient to operate, and is safe and reliable.
Description
Technical field
The present invention relates in electric power system for switch cubicle in transformer station, is the Intelligent switch cabinet type locking device that a kind of personnel of preventing are strayed into charged compartment in high-tension switch cabinet specifically.
Background technology
Anti-misoperation locking device is the visual plant that transformer station prevents " five large types " misoperation, and misoperation-proof locking device is the important leverage of the person, electrical network and device security stable operation reliably.18 the great anti-accident measures > of electrical network > of < < State Grid Corporation of China point out: high-tension switch cabinet should be selected the product of " five is anti-" complete function.The electric power safety working regulation > > of < < State Grid Corporation of China also clearly stipulates: high voltage electric equipment all should be installed perfect misoperation-proof locking device.And have perfect anti-misoperation locking device function, what do not have anti mis-closedown function should install mechanical lock additional.
At present, ZS1 type switch cubicle is the 10kV switch cubicle product of ABB AB's development and production, its cable vault's door is by fastened by screw, no matter banded cable is not charged, with special-purpose cranking bar even screwdriver door can be opened, do not possess anti-incorrect manipulation deadlock function, violate above-mentioned rules requirement, very easily cause personnel's electric shock accidents.
Summary of the invention
The present invention seeks to for the deficiencies in the prior art, propose a kind ofly safe to only have in cabinet really in the situation without electric the Intelligent switch cabinet type locking device that cabinet door just can be opened.
The present invention can reach by following measure:
A kind of Intelligent switch cabinet type locking device, comprise the cabinet with cabinet door, electromagnet, T shape hook and L shaped fixed head, it is characterized in that electromagnet is provided with centre bore, in centre bore, be provided with gag lever post, fixed head one side is connected with cabinet door, and electromagnet is fixed on the opposite side of fixed head, T shape is linked up with corresponding with gag lever post and is fixed on the cabinet of cabinet door one side, and electromagnet wire is connected with the earth connection in cabinet.
Gag lever post described in the utility model adopts nonmagnetic substance to make, the middle part of gag lever post is provided with the back-up ring of being made by magnetic material, when electromagnet is charged, back-up ring is attracted on electromagnet, hook is free shape, when electromagnet dead electricity, gag lever post falls under gravity in hook, and hook is spacing shape.
Earthing device closure or circuit breaker (runner wagon) are in test position in the cabinet for the utility model, and electromagnet is charged, gag lever post adhesive, and hook loses obstruction, thus cabinet door can be opened; In cabinet earthing device open or circuit breaker (runner wagon) not in test position, latching electromagnet dead electricity, gag lever post falls, and blocks hook, cabinet door cannot be opened, and has the advantages such as simple, easy to operate, safe and reliable are installed.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure: a kind of Intelligent switch cabinet type locking device, comprise the cabinet 7 with cabinet door 6, electromagnet 1, T shape hook 2 and L shaped fixed head 3, above-mentioned same as the prior art, this does not repeat, of the present utility modelly be characterised in that electromagnet 1 is provided with centre bore, in centre bore, be provided with gag lever post 4, fixed head 3 one sides are connected with cabinet door, electromagnet 1 is fixed on the opposite side of fixed head 3, the hook of T shape hook 2 is corresponding with gag lever post 4 and be fixed on the cabinet of cabinet door one side, electromagnet 1 wire is connected with the earth connection in cabinet, described gag lever post 4 adopts nonmagnetic substance to make, the middle part of gag lever post is provided with the back-up ring 5 of being made by magnetic material, when electromagnet is charged, back-up ring is attracted on electromagnet, hook is free shape, when electromagnet dead electricity, gag lever post falls under gravity in hook, hook is spacing shape, the utility model in the cabinet earthing device closure or circuit breaker (runner wagon) in test position, electromagnet is charged, gag lever post adhesive, hook loses obstruction, thereby cabinet door can be opened, in cabinet earthing device open or circuit breaker (runner wagon) not in test position, latching electromagnet dead electricity, gag lever post falls, and blocks hook, cabinet door cannot be opened, and has the advantages such as simple, easy to operate, safe and reliable are installed.
