Description

Clamp-on ammeter of novel lighting device

Technical Field

The utility model relates to an electric power system secondary circuit needs to carry out the auxiliary assembly that electric current numerical value measured, especially relates to novel lighting device's clamp type ampere meter.

Background

In the field of electric power systems or other related work and life, a digital clamp ammeter is a common tool for electricians, and can be generally used for measuring current numerical parameters in a system loop, such as three-phase asynchronous motor alternating current, low-voltage bus current, knife switch loop current and the like, and is widely used.

The existing digital clamp-on ammeter generally comprises a clamp-on ammeter body and a measuring coil, wherein a measuring circuit connected with the measuring coil through an electric wire is arranged in the digital clamp-on ammeter body, and a display screen connected with the measuring circuit is arranged on the digital clamp-on ammeter body. However, in the process of frequent practical use, it is found that there is an operational disadvantage in this case, that is, when the clamp ammeter is used to measure the current value of the electrical circuit in a particularly narrow and dark corner, the problem of insufficient light is often encountered, even if there is an external auxiliary light source, the shadow effect of the worker still exists, the ghost or shadow phenomenon occurs, and the sight line of the worker is further affected, and particularly in the relay protection maintenance operation process of the power system, the situation phenomenon is more frequent. If relay protection personnel often work in narrow protection screen internal portion, often can't see the surrounding environment because interior lighting is not enough this moment, the condition such as miss bumping takes place very easily. Even if a lighting tool such as a flashlight is provided outside, a large shadow area exists due to a narrow space, and a good lighting effect is lost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel lighting device's clamp type ampere meter to solve the digital clamp type ampere meter pen-shape metre light direction that exists among the prior art and can not adjust, be difficult to in the use to the cabinet incasement equipment and other equipment places that light is weak carry out the technical problem that throws light on.

The utility model discloses a realize like this:

the utility model provides a novel lighting device's clamp-on ammeter, includes clamp-on ammeter casing, gear range regulating switch, liquid crystal display, hand-push type measuring coil switch, measuring coil, wherein, is equipped with the hi-lite LED lamp at clamp-on ammeter casing front end, and button cell is contained to this hi-lite LED lamp to be equipped with LED lamp switch in clamp-on ammeter casing side and be used for controlling the hi-lite LED lamp.

In the foregoing, the high-brightness LED lamp is provided with two or more than two LED lamps at the front end of the case of the clamp-type current meter. In addition, the high-brightness LED lamp is provided with an angle adjusting component.

The utility model discloses when the thinking originated from supply company, power plant in every year need measure numerical value to asynchronous motor electric current in the station, low pressure generating line return current, the often constrictive internal unable clear return circuit of cabinet is other, even there is external light source's auxiliary action, nevertheless influences because of staff's shadow, still sees the condition of unclear looks, seriously influences the exactness of staff's operation. The utility model discloses a locate the small LED lamp illuminator of device at clamp type ampere meter gauge outfit, and this illuminator can carry out corresponding angular adjustment, then effectual this problem of having solved.

The utility model has the advantages that:

the clamp-on ammeter of the utility model is provided with the luminous LED lamp, thereby enhancing the illumination effect and avoiding the possibility that the body part accidentally touches the electrified equipment; the LED lamp device can realize angle adjustment, and overcomes the defect of a 'spot light pole' of vertical irradiation of the prior lamp pole; the light-emitting device can also be applied to other meters and the like, and has certain universality.
