Abstract
The utility model discloses a mistakenly open preventive high-voltage switchgear which comprises a cabinet body with a cabinet door, wherein a circuit breaker is disposed in the cabinet body and provided with a switching-on switch and a cutting-off switch, and the cabinet door comprises a lock matched with the switching-on switch. Preferably, the lock is a mechanical type lockset provided with a latch hook and an electromagnet matched with the latch hook, the electromagnet is matched with the switching-on switch, and simultaneously the latch hook is connected with a reset spring. The mistakenly open preventive high-voltage switchgear has the advantages that mistakenly open of the cabinet door can be effectively prevented, and operation of machinery equipment cannot be influenced.
Description
Technical field
The utility model relates to the switch cubicle technical field, especially relates to a kind of avoiding improper opening high-tension switch cabinet.
Background technology
Travel switch is installed in order to anti-misoperation on the cabinet door of high-tension switch cabinet.That is, when breaker closing, if there is the people that door of switch cabinet is opened, circuit breaker trip.Like this, although can avoid cabinet door mistake to open rear cause danger, circuit breaker can impact the normal operation of plant equipment after disconnecting, very inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of avoiding improper opening high-tension switch cabinet, and it has can effectively avoid the cabinet door to be opened by mistake, thus the characteristics that can not impact the normal operation of plant equipment.
The technical scheme that the utility model adopts is: the avoiding improper opening high-tension switch cabinet, comprise the cabinet that is provided with the cabinet door, and be provided with circuit breaker in this cabinet, this circuit breaker has closing switch and disconnect, described cabinet door includes lockset, and this lockset and this closing switch match.
Described lockset is mechanical lockset, the electromagnet that this mechanical lockset has latch hook and with this latch hook, matches, and this electromagnet and this closing switch match, and simultaneously, this latch hook is connected with back-moving spring.
The advantage that compared to the prior art the utility model has is: can effectively avoid the cabinet door to be opened by mistake, thereby can the work of plant equipment not impacted.Avoiding improper opening high-tension switch cabinet of the present utility model in use, in case closing switch start, closing of power circuit breaker, this lockset locking, this cabinet door can't be opened, thereby avoided this cabinet door to be opened by mistake, and then can not impact because of the normal operation that circuit breaker opens circuit to other plant equipment.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the front view of embodiment of the present utility model;
Fig. 2 is the work schematic diagram of latch hook of the present utility model and electromagnet.
In figure: 10, cabinet, 11, the cabinet door; 20, circuit breaker, 21, closing switch, 22, disconnect; 30, lockset, 31, latch hook, 32, electromagnet.
Embodiment
Embodiment, as shown in Figure 1: the avoiding improper opening high-tension switch cabinet, comprise the cabinet 10 that is provided with cabinet door 11, and be provided with circuit breaker 20 in this cabinet 10, this circuit breaker 20 has closing switch 21 and disconnect 22.More particularly, this cabinet door 11 includes lockset 30, and this lockset 30 and this closing switch 21 match.That is, in case this closing switch 21 starts, this circuit breaker 20 is connected, these lockset 30 lockings, this cabinet door 11 can't be opened, and only when this disconnect 22 starts, makes this circuit breaker 20 be off state, and this lockset 30 is opened, and this cabinet door 11 can be opened.Like this, avoided this avoiding improper opening high-tension switch cabinet in working order when (being the state of closing of power circuit breaker) this cabinet door 11 opened by mistake.
Optimize, as shown in Figure 2: this lockset 30 be mechanical lockset, the electromagnet 32 that this mechanical lockset has latch hook 31 and with this latch hook 31, matches, and this electromagnet 32 matches with this closing switch 21, and simultaneously, this latch hook 31 is connected with back-moving spring 33.Certainly, this back-moving spring 33 can be torsion spring.Namely, in case this closing switch 21 starts, this circuit breaker 20 is connected, this electromagnet 32 is switched on and is produced magnetic force, adsorb this latch hook 31 overcome back-moving spring 33 pulling force and after moving with cabinet door 11 lockings, only when starting, this disconnect 22 make this circuit breaker 20 be off state, this electromagnet 32 cuts off the power supply and loses magnetic force, thereby this latch hook 31 resets under the pulling force effect of this back-moving spring 33, and then this cabinet door 11 can be opened.Obviously, mechanical lockset is more reliable, and structure is more simple.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
