Abstract
The utility model discloses a high voltage switch cabinet of a lightning arrester handcart with a discharge counter. The lighting arrester is installed on a voltage transformer handcart; the discharge counter is installed in a cabinet body; and the lighting arrester and the discharge counter are connected through dynamic and static plugs. When the voltage transformer handcart is arranged in the cabinet body and the dynamic and static plugs are interlocked, the lightning arrester is in a normal working condition; and when the voltage transformer handcart is drawn out of the cabinet body, the dynamic and static plugs are separated, and the lightning arrester is powered off and is in a maintenance state. According to the utility model, the simple and reasonable structure, convenient operation, safe and reliable use, low maintenance and manufacturing cost, and great popularization value are realized.
Description
Technical field
The utility model relates to a kind of for electric equipment, in particular for the high-tension switch cabinet of connection cable.
Background technology
High-tension switch cabinet is a kind of switchgear assembly and control appliance.It is as power center (PC) and main switching compound.Main control, supervision, measuring and protection with doing power circuit, main power consumption equipment.Being normally placed in transformer station, switchgear house etc. locates.In cabinet, electric elements mainly contain major loop equipment and auxiliary equipment.
Lightning arrester is for protecting various electric equipments in electric power system to avoid that lightning overvoltage, switching overvoltage, Frequency Transient Overvoltage are impacted and an electrical equipment damaging.Therefore, lightning arrester is the indispensable part of high-tension switch cabinet, and discharge counter is the requisite auxiliary equipment of lightning arrester.The existing lightning arrester in market installs mode additional and is generally lightning arrester and is arranged on cabinet, and is connected with main busbar by sleeve pipe, for electric power system provides metering, monitoring, protection, sampling power supply, is also the most typical design of electric power system.But in use also finding some shortcomings and disadvantage, is mainly that voltage transformer and lightning arrester be not on a handcart, even counter of lightning arrester cannot be installed on a handcart time.To install mode additional be to make separately an arrester handcart to common a kind of lightning arrester in addition, and this causes again manufacturing cost to increase.The reason that causes above problem is because discharge counter profile is larger, cannot be arranged on voltage mutual inducer trolley, and lightning arrester links with discharge counter direct requirement cable, and cable specification is larger, takes up room large.And national grid also requires lightning arrester must be arranged on voltage mutual inducer trolley now, can realize and see lightning arrester discharge number of times.
Utility model content
The purpose of this utility model is to provide a kind of high-tension switch cabinet of arrester handcart belt discharge counter, and the discharge time of visible lightning arrester, can get rid of in time to the system failure.Do not need to manufacture separately arrester handcart, reduce manufacturing cost.
For achieving the above object, the utility model has adopted following technical scheme: cabinet comprises the voltage mutual inducer trolley that can advance pull-out cabinet, vertical fixing cabinet median septum; Lightning arrester is installed on voltage mutual inducer trolley, and voltage mutual inducer trolley is installed the first location counterpart and moving plug near one end of cabinet median septum; On cabinet median septum, discharge counter is installed, cabinet median septum is installed second near the one side of voltage mutual inducer trolley and is coordinated keeper and quiet plug; Between lightning arrester and moving plug, with wire, connect, between discharge counter and quiet plug, with wire, connect, the first location counterpart and the second cooperation keeper cooperatively interact and realize moving plug and quiet slotting interlock energising.
The utility model has the advantages that; Adopt unique sound plug switching form, while advancing cabinet inner on voltage mutual inducer trolley, lightning arrester and discharge counter energising, in normal operating conditions, when handcart exits, sound plug separates, and can realize the discharge time of lightning arrester and observe, thereby distribution system fault is got rid of and played promptly and accurately.The utility model is simple in structure, uses flexibly, can bite, and accurate positioning.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, when needs exit distribution system to lightning arrester 2, voltage mutual inducer trolley 1 is pulled out to cabinet, moving plug 4 is separate with quiet plug 8, now, lightning arrester 2 power-off and the not power-off of whole cabinet device can realize the in the situation that of whole not power-off of cabinet device lightning arrester is overhauled.After lightning arrester maintenance is complete, handcart 1 is pushed to cabinet, moving plug 4 and the 8 interlock energisings of quiet plug, lightning arrester 2 enters operating state.
On voltage mutual inducer trolley 1, the implementation of the first location counterpart 3 is that several alignment pins are installed on voltage mutual inducer trolley 1, second to coordinate the implementation of keeper 7 be on position corresponding on cabinet median septum 5, to beat the dowel hole of equal number, can guarantee to move plug 4 and the accurate interlock of quiet plug 8.
In order to guarantee better moving plug 4 and the accurate interlock of quiet plug 8, can also be at the larger alignment pin 9 of voltage mutual inducer trolley 1 front end installation dimension, on cabinet median septum 5, on corresponding position, beat dowel hole, guarantee the first location of moving plug 4 and quiet plug 8, and then guarantee the more accurately location of moving plug 4 and quiet plug 8.
Although the utility model has been made to detailed description with above-mentioned preferred embodiment, has not limited the utility model with above-described embodiment.Those skilled in the art should recognize in the case of not departing from technical solutions of the utility model given technical characterictic and scope; increase that technical characterictic is done, with the replacement of some same contents of this area, all should belong to protection range of the present utility model.
