Abstract

The utility model relates to a double-gate sub-step fool-proof interlocking machine room switch, which is characterized in that a cabinet body is provided with isolating plates therein; the corresponding upper and lower layers of cabinets are provided with an upper and a lower mobile doors with sub-step locks; the upper and lower layers of cabinets are provided with bottom plates, which are provided with a control power supply and a car illumination breaker, a breaker of a control well hole illumination circuit. When the breaker is in working state, the upper mobile door can be closed but not be locked, therefore, in emergency, the mobile door can be opened closely, for cutting off the power supply. When the breaker is in cutoff state, the two mobile doors are closed and locked, which can guarantee repair personnel life safety, and avoid danger occurrence. Particularly, when only need to operate and lock the breaker of the control well hole illumination circuit in the control cabinet, no need to cut off the control power supply breaker, with no influence on normal operation and realization of convenient operation.

Description

Two-door substep interlocking anti-misoperation machine room switch

Technical field

The utility model belongs to H01H electric switch class technology, particularly relates to a kind of two-door substep interlocking anti-misoperation machine room switch.

Background technology

Present known machine room switch, form by the circuit breaker that control illumination and power are housed in the cabinet of control cubicle, because structural reason own, so when switch is in running status, when being closing of power circuit breaker, the cabinet door opens wide, and so in a single day misoperation takes place, and can bring out the generation of dangerous incident; Especially when circuit breaker disconnected, the cabinet door opened wide, in case misoperation has the generation of maintainer's Danger Electric shock risk at any time.Also has a kind of disclosed substep interlocking anti-misoperation machine room switch, be by by the control cubicle of substep lock is housed, and various circuit breakers are housed in the cabinet of control cubicle constitute, the hazard event that brings in case the switch of this structure can be avoided misoperation takes place takes place, but when the circuit breaker of controlling power disconnects and locks, can't control wherein the circuit breaker of control hoistway lighting circuit in the control cubicle, otherwise, when needs only to control cubicle in wherein the circuit breaker of control hoistway lighting circuit operate and when locking, also must cut off whole circuit breakers just can carry out, so not only influence the operate as normal of switch, and operation is also very not convenient.

Summary of the invention

The utility model need not cut off the two-door substep interlocking anti-misoperation machine room switch that whole circuit breakers just can be operated the circuit breaker of control well lighting for the technical problem that exists in the solution known technology provides a kind of.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

The utility model is the cabinet by control cubicle, base plate, socket, circuit breaker, the dodge gate that has the substep lock is formed, it is characterized in that, be built-in with at the cabinet of control cubicle and make on cabinet constitutes, following two-layer dividing plate, on the cabinet of the cabinet upper strata of control cubicle correspondence, install dodge gate, dodge gate under installing on the cabinet of the cabinet lower floor correspondence of control cubicle, last, the substep lock all is housed on the following dodge gate, cabinet upper strata at control cubicle is built-in with base plate, the circuit breaker of the circuit breaker of installation and control electrical source of power and control cage illumination on its base plate, in the cabinet lower floor of control cubicle, also be equipped with base plate, the circuit breaker of installation and control well lighting circuit on its base plate.

Advantage and the good effect that the utlity model has are: easy to operate and closed tight.When circuit breaker is in running order,, therefore in accident, is convenient to open rapidly dodge gate and cuts off the electricity supply though the last dodge gate of control cubicle closes and can not lock in the utility model.When circuit breaker was in dissengaged positions, two dodge gates of the present utility model were kept in detention and control cubicle are locked, and have not only guaranteed maintainer's life security, and have avoided dangerous generation again.Especially when needing only the circuit breaker of the control hoistway lighting circuit in the cabinet of control cubicle to be operated, the following dodge gate of only opening control cubicle just can carry out, and need not cut off whole circuit breakers, and neither influence the operate as normal of switch, realized the purpose of convenient operation again.

Description of drawings

Fig. 2 is the utility model open mode structural representation;

Fig. 3 is an A-A cross-sectional view among Fig. 1;

Fig. 4 is a B-B cross-sectional view among Fig. 1.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 and Fig. 2, for realizing when needing only the circuit breaker of the control hoistway lighting circuit in the cabinet of control cubicle to be operated, need not cut off whole circuit breakers just can carry out, neither influence the operate as normal of switch, realize the purpose of convenient operation again, therefore dividing plate 19 is placed in the cabinet 1 of control cubicle, cabinet 1 is formed, following two-layer structure, on the cabinet of the upper strata of cabinet 1 correspondence, install dodge gate 2, dodge gate 7 under installing on the cabinet of cabinet 1 lower floor's correspondence, substep is housed on last dodge gate 2 locks I, on following dodge gate 7, substep is housed and locks II, be built-in with base plate 14 on the upper strata of cabinet 1, the circuit breaker 15 of the circuit breaker 13 of installation and control cage illumination and control electrical source of power on the base plate 14, in the lower floor of cabinet 1, also be equipped with base plate 18, the circuit breaker 17 of installation and control well lighting circuit on base plate 18.In addition, for easy to use, can also mounting receptacle 12 on the side arm of control cubicle.

In above-mentioned last, the substep lock I that installs respectively on the following dodge gate, the structure of II is identical, its concrete structure is, please consult Fig. 3 and Fig. 4 again, last, following

dodge gate

2,7 the inside all is shaped on reinforcement 8, on each reinforcement 8 all spacing distance install two supporting brackets 10 that have through hole on it, all having through hole 20 on dodge gate 2 and the following dodge gate 7 on the close reinforcement 8 separately, at the within and without of last dodge gate 2 and following dodge gate 7 rocking arm 9 and handle 3 are installed respectively by through hole 20, adorn the jam plate 5 that has lockhole 21 in movable company of the other end of rocking arm 9, jam plate 5 can stretch out on control cubicle, the through hole 4 that each self-corresponding jam plate 5 position has on the two-layer down cabinet 1, end and centre position in jam plate 5 bottoms are shaped on postive stop baffle 11 respectively, the effect of postive stop baffle 11 is, when the circuit breaker 15 of control electrical source of power is connected, on the control cubicle, following dodge gate 2, the 7th, shut, and postive stop baffle 11 just in time is stuck in the removing 16 of circuit breaker 15 of control electrical source of power, so in a single day, meet dangerous the generation, can conveniently cut off the power supply.Again when the circuit breaker 15 of control electrical source of power disconnects, the lockhole 21 that stretches out the control cubicle outer end by jam plate 5 can snap in button and hang 6, hangs 6 by button and installs lock additional, to guarantee different work maintainer's safety.
