Abstract
The utility model relates to an iron casing switch, in particular to a low pressure electrical device iron casing switch used for circuit control. The low pressure electrical device iron casing switch is characterized in that an operation handle and a spring switch mechanism of the iron casing are positioned on the left side of an iron casing switch box; and the upper and the lower positions of a right side plate of an iron casing switch box body are respectively provided with two zero-line connection bolts. An Operator can stagger bodies to stand on the left side of the iron casing switch, when the iron casing switch is operated by a right hand, so the operator is free from being burnt in face and chest because of arc generated by short circuit in the iron casing switch during the switching on process. A power zero-line and a phase line are cut to the same length, the wastage of the phase line is reduced, and the power zero-line and a device zero connecting protective line are convenient to be connected. The security is effectively enhanced, and the damage to the operator because of the short circuit of the switch during the switching on process is avoided.
Description
Technical field
A kind of enclosed knife switch relates to a kind of low-voltage electrical apparatus enclosed knife switch that is used for circuit control.
Background technology
The formula enclosed knife switch is put on traditional handle right side, because most people are right-handed.So, when enclosed knife switch is operated, stand on the front of enclosed knife switch often, in case enclosed knife switch inside is short-circuited or during earth fault, the arclight of its generation and blast can be washed switch cover open, face and chest to operating personnel damage, and such accident happens occasionally.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively improve security performance, avoids in the closing operation process enclosed knife switch of the injury that operating personnel caused because of the switch internal short-circuit.
The purpose of this utility model is achieved through the following technical solutions.
A kind of enclosed knife switch is characterized in that the operating grip of its enclosed knife switch and the left side that the spring switching-on mechanism is positioned at the enclosed knife switch case; At the upper-lower position of enclosed knife switch casing right plate, two zero line connection bolts are set respectively.
Enclosed knife switch of the present utility model, stand in the enclosed knife switch left side in the operating personnel body position of can staggering, when enclosed knife switch being operated with the right hand, can effectively avoid in making process, the arc light that produces because of the enclosed knife switch internal short-circuit, the accident of burning that people's face and chest caused takes place.Zero-power line and phase line are cut into identical length, reduce the waste of phase line, the articulating of be more convenient for zero-power line and equipment zero connection protection line.Effectively improve security performance, avoid the injury that in the closing operation process, operating personnel caused because of the switch internal short-circuit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of enclosed knife switch, the operating grip 1 of its enclosed knife switch and spring switching-on mechanism 2 are positioned at the left side of enclosed knife switch case 3; At the upper-lower position of enclosed knife switch casing right plate, two zero line connection bolts 4,5 are set respectively.
The utility model is the local improvement of carrying out at traditional iron-clad switch knob position, with its operating grip and switching-on mechanism, is arranged on the left side of enclosed knife switch casing; Because put on a handle left side, the door closure that need will open left changes into to the right and opening; To be positioned at the connection bolt that is used for connecting to neutral on the connection bolt of ground protection of enclosed knife switch sidepiece and the newly-increased enclosed knife switch originally, moved to the no handle side of enclosed knife switch, when making things convenient for wiring, be not subjected to the influence of handle position; When operating personnel operate, can stand, make face and chest in the process of closing a floodgate, can avoid the front, avoid the injury that might take place with respect to enclosed knife switch in the left side of enclosed knife switch.Be not difficult to find out that the utility model on the basis that does not influence the original every function of switch, has increased security performance.
