Abstract
A full sealed compound insulation metallic oxide arrester comprises an arrester body and is characterized by also comprising an insulation cover and an insulation lead, wherein the insulation cover is installed at the upper part of the high voltage end of the arrester body, the insulation lead is connected with the high voltage end of the arrester body by the insulation cover, and the insulation cover has a flat top and conic structure. By adopting the full sealed compound insulation metallic oxide arrester, the insulation distance between phase and phase as well as between phase and ground are reduced, safety performance of the product is improved and the volume of a switch cabinet can be reduced when the arrester is used in the switch cabinet, thus reducing cost.
Description
Technical field
The utility model relates to the lightning arrester field.
Background technology
Along with the aggravation of market competition, competitiveness of product is all improving by every means in switch cubicle producer, and how under the prerequisite of ensuring the quality of products, the nature that reduces cost has to greatest extent become the problem of the most important thing.Existing lightning arrester is in the process of installing and using, and the mounting distance of lightning arrester must not be less than the standard-required of insulation coordination, otherwise can cause alternate or flashover relatively, thereby has an accident.For the operation that ensures safety, the insulation distance between phase-phase, the phase-ground is bigger, thereby the size of switch cubicle and volume are bigger, and cost is higher.
Summary of the invention
For the insulation distance that solves between lightning arrester phase-phase, the phase-ground is bigger, the size of switch cubicle and volume are big, cost is than problems such as height, and the utility model provides a kind of hermetically sealed composite insulating metal oxide lightning arrester.
The technical scheme that the utility model is adopted for achieving the above object is: hermetically sealed composite insulating metal oxide lightning arrester, comprise lightning arrester body, it is characterized in that: also comprise insulating cover and insulated conductor, insulating cover is installed on the top of the high-pressure side on the lightning arrester body, and insulated conductor is connected with high-pressure side on the lightning arrester body via insulating cover.
Described insulating cover is the pyramidal structure of flat-top.
Hermetically sealed composite insulating metal oxide lightning arrester of the present utility model can reduce the insulation distance between phase-phase, the phase-ground, when having improved the security of products energy, is applied on the switch cubicle and can dwindles switch cubicle volume, cost squeeze.Under the certain situation of switch cubicle size, can improve operational reliability, can obtain good technology-economic benefit.
Description of drawings
Fig. 1 is hermetically sealed composite insulating metal oxide lightning arrester structure chart.
Embodiment
Hermetically sealed composite insulating metal oxide lightning arrester as shown in Figure 1, by lightning arrester body 1, insulating cover 2 and insulated conductor 3 are formed, insulating cover 2 is installed on the top of the high-pressure side on the lightning arrester body 1, insulated conductor 3 is drawn from the high-pressure side on the lightning arrester body 1 via insulating cover 2, insulating cover 2 is a pyramidal structure, and conical top is a plane.Adopt hermetically sealed composite insulating metal oxide lightning arrester, under continuous operating voltage, the insulation of lightning arrester high-pressure side, the contact in short-term of insulated conductor part, lead contact the accident that can not be short-circuited in short-term with ground wire, have improved operational reliability greatly.Simultaneously, can reduce the insulation distance between phase-phase, the phase-ground, when having improved the security of products energy, be applied on the switch cubicle and can dwindle switch cubicle volume, cost squeeze.
Claims (2)
1. hermetically sealed composite insulating metal oxide lightning arrester, comprise lightning arrester body, it is characterized in that: also comprise insulating cover and insulated conductor, insulating cover is installed on the top of the high-pressure side on the lightning arrester body, and insulated conductor is connected with high-pressure side on the lightning arrester body via insulating cover.
2. hermetically sealed composite insulating metal oxide lightning arrester according to claim 1 is characterized in that: described insulating cover is the pyramidal structure of flat-top.
