Description

Anti-false switching-on operation device with intelligent column switch integrated for one time and two times

Technical Field

The utility model belongs to the technical field of the electrical equipment technique and specifically relates to indicate that a secondary fuses mistake combined floodgate operating means that prevents of intelligent column switch.

Background

The outdoor one-time and two-time fusion intelligent pole-mounted switch is commonly used for rural power grids and urban power grid systems and is used for load current, overload current and short-circuit current division and combination, line loss measurement and short-circuit grounding fault protection. The Chinese patent with publication number CN 203910663U discloses a column vacuum circuit breaker, which comprises a column vacuum circuit breaker body, wherein a wiring terminal is arranged on the column vacuum circuit breaker body, a main box body is connected below the column vacuum circuit breaker body, a manual opening and closing handle, an energy storage handle and an opening and closing indicating box body are arranged on the main box body, and the column vacuum circuit breaker also comprises an operating mechanism and a control mechanism, wherein the operating mechanism is positioned in the main box body and is respectively matched with the manual opening and closing handle and the energy storage handle; the control mechanism is positioned in the split-combination indicating box body and is connected with the wiring terminal.

The pole vacuum circuit breaker with the structure can realize electric energy storage and electric opening and closing, and can also realize manual energy storage and manual opening and closing. The control mechanism can be arranged to realize on-site switching operation and remote control operation through a communication interface, if a special wireless remote controller is selected to realize remote control operation, the control box is connected to realize on-site operation, or remote control is realized through a communication network, power cut and power transmission can be realized without rod mounting, the functions of protection, communication and automatic monitoring are realized, and the requirement of informatization of a power system is met.

However, the above-described pole vacuum circuit breaker still has some disadvantages: if the outdoor staff operates on the spot (namely, manually opens and closes the brake), the staff of the remote monitoring center cannot predict whether the above actions are automatic actions or manual actions of the vacuum circuit breaker on the column. If the operating mechanism is automatically restored to the closing state by the staff in the remote monitoring center, great danger is brought to outdoor staff, and serious potential safety hazards exist. Therefore, the anti-false switching-on operation device with the intelligent pole top switch integrated for the first time and the second time is provided.

Preferably, the rotating base fixing plate is formed by bending a steel plate and is attached to the upper portion of a main box body of the secondary integrated intelligent column switch, the rotating base fixing plate is provided with an installation lug matched with a hanging ring of the secondary integrated intelligent column switch, a bolt hole is formed in the installation lug, a bolt penetrates through the bolt hole, and the bolt is locked on the hanging ring through a connecting ring and a nut.

Further, the gear lever rotating seat is fixedly welded on the outer side wall of the rotating seat fixing plate.

Furthermore, the stop lever rotating seat is provided with a through hole for installing the vertical rotating rod, a rotating shaft limiting groove is arranged in the through hole, and a limiting bulge matched with the rotating shaft limiting groove is correspondingly arranged on the vertical rotating rod.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

1. this structure prevent mistake combined floodgate operating means reaches normal operating and the maloperation to the combined floodgate handle through the rotatory swing to L type shelves pole, when the horizontal pendulum rod of L type shelves pole rotatory to with combined floodgate handle in vertical projection crossing state, the combined floodgate handle can't carry out the combined floodgate operation, otherwise when horizontal pendulum rod and combined floodgate handle in vertical projection non-intersect, the combined floodgate handle can carry out normal combined floodgate operation. Therefore, the utility model discloses a prevent mistake combined floodgate operating means can effectively stop the mistake combined floodgate that a secondary fuses intelligent column switch remote monitoring center, has guaranteed operation maintenance personal's life safety on the spot.

2. The anti-misoperation closing operation device with the structure ingeniously utilizes the characteristic that a secondary fuses intelligent pole top switch rings, enables the rotating seat fixing plate to be fixedly combined with the rotating seat fixing plate, is simple and convenient to install, does not need to change the existing secondary fusion intelligent pole top switch appearance structure, and is low in modification cost.
