Abstract
The utility model discloses a drawing switch equipment checking trolly, which is characterized in that the drawing switch equipment checking trolly comprises a base plate trolly, wherein a framework is arranged on the base plate trolly, the back side of the framework is provided with a simulated circuit breaker, an observing window is arranged on the framework, and the opening and closing conditions of a valve and the insertion contact condition of a primary contact can be directly observed through the observing window for preventing the short circuit accident caused by insufficient opening of the valve and the equipment severe heating accident caused by insufficient insertion contact of the primary contact in the normal operation process of the 10kV indoor metal armouring drawing switch equipment.
Description
Technical field
The utility model relates to a kind of inspection dolly of power equipment, and particularly a kind of 10kV indoor metal armoring is extracted switchgear check trolley out.
Background technology
The 10kV indoor metal armoring draw out switchgear is widely used.Because the 10kV indoor metal armoring draw out switchgear is an enclosed construction, valve can not enter the working position to the isolating switch dolly in use and assembling process after opens situation and one-time contact insertion situation is observed, detected, when valve is opened not exclusively or contact inserts under the insufficient situation of contact, if the breaker closing operation causes major accidents such as the serious heating of short circuit or equipment easily.For this reason, the applicant has developed a kind of 10kV indoor metal armoring draw out switchgear check trolley with view window.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of extraction switchgear check trolley, can see directly that by this inspection dolly the valve of isolating switch after entering the working position open situation and one-time contact and insert situation, to prevent that the 10kV indoor metal armoring draw out switchgear from taking place to open the short circuit accident that not exclusively causes or insert insufficient seriously heating accident of equipment that causes that contacts because of one-time contact because of valve in course of normal operation.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of extraction switchgear check trolley is characterized in that it comprises chassis, and framework is installed on the chassis, and the rear side of framework is equipped with mimic-disconnecting switch, and described framework is provided with view window.
On the mimic-disconnecting switch of the present utility model contact arm is installed, the end of contact arm is equipped with contact.
As the utility model improvement of the technical scheme, the aviation socket is installed on the described mimic-disconnecting switch.
The beneficial effects of the utility model are: based on said structure, the utility model can replace the isolating switch dolly of actual motion, and observes directly unlatching and the closed condition and the one-time contact insertion contact condition of valve by view window.Whether normally open by observation and inspection dolly metal dampers baffle plate in being pushed into the process of working position and to put in place, thereby whether the contact arm of judging the isolating switch dolly is in operation valve is produced discharge or contact and causes short circuit accident.Whether normally insert contact by observation and inspection dolly one-time contact in being pushed into the process of working position, thereby whether the one-time contact of judging the isolating switch dolly normally inserts contact, prevents that one-time contact is because of seriously heating accident of loose contact generation equipment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2, the disclosed a kind of extraction switchgear check trolley of the utility model, comprise chassis 1, framework 2 is installed on the chassis 1, the rear side of framework 2 is equipped with mimic-disconnecting switch 3, contact arm 4 is installed on the mimic-disconnecting switch 3, and the end of contact arm 4 is equipped with contact 5, and framework 2 is provided with view window 6.The chassis structure that the utility model adopts is consistent with the isolating switch dolly chassis structure of actual motion; Mimic-disconnecting switch of the present utility model is identical with the structure of actual isolating switch, and the isolating switch dolly of structure of the present utility model, size and installation site and actual motion is in full accord, and the utility model can replace the isolating switch dolly of actual motion to observe unlatching and the closed condition and the one-time contact insertion contact condition of valve like this.Whether normally open by observation and inspection dolly metal dampers baffle plate in being pushed into the process of working position and to put in place, thereby whether the contact arm of judging the isolating switch dolly is in operation valve is produced discharge or contact and causes short circuit accident.Whether normally insert contact by observation and inspection dolly one-time contact in being pushed into the process of working position, thereby whether the one-time contact of judging the isolating switch dolly normally inserts contact, prevents that one-time contact is because of seriously heating accident of loose contact generation equipment.
As shown in the figure, aviation socket 7 is installed on mimic-disconnecting switch 3, aviation socket 7 can be connected with external plug so that when the utility model is provided at use the mains lighting supply of framework inside.
By the utility model in the operating process that advances and pull out, operating personnel can observe unlatching and the closed situation and the one-time contact insertion situation of valve baffle plate by checking the view window on the dolly, thereby judge that isolating switch dolly valve when the real work position is opened situation and one-time contact inserts contact condition, to prevent that the 10kV indoor metal armoring draw out switchgear from taking place to open the short circuit accident that not exclusively causes or insert insufficient seriously heating accident of equipment that causes that contacts because of one-time contact because of valve in course of normal operation.
The above only is preferred embodiment of the present utility model, can not limit protection domain of the present utility model with it.So long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
