Abstract
The utility model discloses an operation spanner special for a switch cabinet, and relates to the technical field of construction tools of switch cabinets for electricity use. The operation spanner special for the switch cabinet comprises a spanner body and a sleeve, wherein the sleeve is connected to one end of the spanner body through a universal joint, and the other end of the spanner body is provided with a handle sleeve. The spanner body and the sleeve are connected through the universal joint, and the spanner body can rotate in all directions relative to the sleeve. When operating the switch cabinet at a low position, an operator can rotate the spanner body in a full-circle mode. The operation spanner special for the switch cabinet is convenient to use, improves work efficiency, avoids the contact between the hands of the operator and the ground, and is high in safety.
Description
Technical field
The utility model relates to switch cubicle construction equipment technical field for electric power, relates in particular to a kind of switch cubicle dedicated operations spanner.
Background technology
Switch cubicle is a kind of power equipment, and outside line is introduced into master switch in cabinet, then enters sub-control switch, and each needs to arrange by it along separate routes.The having of high-tension switch cabinet " five is anti-" function: 1, the vacuum circuit breaker dolly in high-tension switch cabinet is after testing position is closed a floodgate, and dolly breaker cannot enter operating position.Earthing in (preventing that on-load from closing a floodgate) 2, high-tension switch cabinet is when co-bit, and dolly breaker cannot enter to close a floodgate.Vacuum circuit breaker in (preventing from closing a floodgate with earth connection) 3, high-tension switch cabinet, when combined floodgate work, coils the machinery on earthing and the locking of cabinet door for cabinet back door.Vacuum circuit breaker in (preventing mistakenly entering charged chamber) 4, high-tension switch cabinet closes a floodgate when work, closes earthing and cannot drop into.When the vacuum circuit breaker in (preventing live connection of ground wire) 5, high-tension switch cabinet closes a floodgate operation in work, cannot exit the operating position of dolly breaker.(preventing on-load broaching tool lock)
Switch cubicle power transmission operating procedure: 1, first install rear shrouding, then shut front Xiamen.2, operational grounding switch spindle and make it separating brake.3, with transfer car(buggy), handcart is pushed in cabinet.4, secondary plug is inserted on static socket, shuts Qian Zhongmen.5, with handle, handcart is pushed into operating position from testing position.6, combined floodgate circuit breaker cart.
Power failure operating procedure: 1, by circuit breaker cart separating brake.2, with handle, handcart is withdrawn into testing position from operating position.3, operating position indicator goes out, and testing position indicator is bright.4, open Qian Zhongmen.5, secondary plug is extracted to static socket.6, with transfer car(buggy), handcart is exited outside cabinet.7, operational grounding switch spindle and make it to close a floodgate.8, open rear shrouding and front Xiamen.
The new 10kV switch cubicle of installing is generally indoor handcart switch cabinet now, for saving space and arrangement convenience, generally arrester cabinet is arranged in to PT(voltage transformer) cabinet below, operating position ground proximity like this, operation that can only half-turn half-turn while using the operation of normal operations crank, to operation, bring very big inconvenience, easily touch hand, cause the problem of slight damage simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of switch cubicle dedicated operations spanner, use described wrench operated switch cubicle have easy to use, efficiency is high, the feature such as safe.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of switch cubicle dedicated operations spanner, comprise wrench body and sleeve, it is characterized in that described sleeve is connected to an end of wrench body by universal joint, the other end of wrench body is provided with grip.
Preferably, described wrench body is provided with arc force section.
Preferably, described grip can freely rotate with respect to wrench body, and bottom outer surface locked with split pin and grip is smooth.
Adopt the beneficial effect that technique scheme produces to be: between wrench body and sleeve, by universal joint, to be connected, wrench body can be rotated to all directions with respect to sleeve, when the lower switch cubicle in position is operated, rotating spanner main body that can whole circle, easy to use, improved operating efficiency, and the problem that operating personnel's hand contacts with ground can not occur, safe.In addition, described spanner simple in structure, low cost of manufacture, has good popularization and prospect of the application.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model;
Wherein: 1, wrench body 11, arc force section 2, sleeve 3, universal joint 4, grip.
The specific embodiment
As shown in Figure 1, a kind of switch cubicle dedicated operations spanner, comprises wrench body 1 and sleeve 2, and described sleeve 2 is connected to an end of wrench body 1 by universal joint 3, and the other end of wrench body 1 is provided with grip 4.Described wrench body 1 is provided with arc force section 11, the handled easily personnel application of force, the operating efficiency that improved easy to use.Described grip 4 can freely rotate with respect to wrench body, and bottom outer surface locked with split pin and grip is smooth, reduces in the process that wrench body rotates the friction with staff.
Between wrench body and sleeve, by universal joint, be connected, wrench body can be rotated to all directions with respect to sleeve, when the lower switch cubicle in position is operated, rotating spanner main body that can whole circle, easy to use, improved operating efficiency, and the problem that operating personnel's hand contacts with ground can not occur, safe.
Applied specific case herein principle of the present utility model and embodiment thereof are set forth, the explanation of above embodiment is just with helping understand method of the present utility model and core concept thereof.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not depart from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
