Abstract
A high-voltage alternating-current demarcation load switch is provided. According to an existing high-voltage load switch, a disconnecting switch is independently arranged outside a casing of the existing high-voltage load switch so as to realize the de-energization of wire exiting ends, as a result, problems of complex structure and large size of a product can be caused, while, with the high-voltage alternating-current demarcation load switch adopted, the above problems can be solved. The high-voltage alternating-current demarcation load switch of the utility model comprises a casing and a switching-on/switching-off handle; the casing is provided with wire entering ends and wire exiting ends; isolation pieces which can rotate inside an inner cavity of the casing are arranged inside the casing; the isolation pieces are provided with flexible connection pieces which are in linkage with the isolation pieces; and one end of each flexible connection piece is fixedly connected with one wire entering end, and the other end of each flexible connection piece is movably connected with one wire exiting end. According to the high-voltage alternating-current demarcation load switch of the utility model, the isolation pieces are designed and are built in the casing of the high-voltage load switch, such that the product can reliably switch off a circuit at the wire exiting ends when the product is under maintenance or performs segmented power outage, and therefore, the safety of workers can be ensured; and the high-voltage alternating-current demarcation load switch of the utility model is advantageous in structural simplicity, small size, and convenience in installation and maintenance.
Description
Technical field
The utility model relates to a kind of high-voltage alternating demarcation load switch.
Background technology
High voltage load switch is the electrical equipment of a kind of function between primary cut-out and high voltage isolator, and normal the series connection with high-tension fuse of high voltage load switch is used in conjunction with, and is used for the control power transformer.High voltage load switch has simple arc-control device, because can certain load current and the overload electric current of break-make.But it can not interrupting short circuit, so its general use of connecting with high-tension fuse is carried out short-circuit protection by fuse.Existing high voltage load switch will be guaranteed the leading-out terminal outage when maintenance or segmentation power failure.Common existing high voltage load switch is independent outside its housing installs isolating switch, although such high voltage load switch can be guaranteed the leading-out terminal outage, has that volume is excessive, installation and shortcomings such as inconvenient operation, production cost height.
Summary of the invention
Existing high voltage load switch is to realize the leading-out terminal outage by the independent isolating switch of installing outside its housing in the background technology in order to solve, so that product structure is complicated, and the problem that volume is excessive, the utility model provides a kind of high-voltage alternating demarcation load switch.
The technical solution of the utility model is: a kind of high-voltage alternating demarcation load switch, comprise housing and deciliter handle, described housing is provided with end of incoming cables and leading-out terminal, being provided with in the described housing can be at the separator of housing inner chamber rotation, described separator is provided with and being flexible coupling that separator is connected, the described end that is flexible coupling is fixedly connected with the end of incoming cables, and the other end and leading-out terminal are flexibly connected.
As a kind of improvement of the present utility model, described separator comprises installation shaft and three insulators that are sheathed on the installation shaft, is equipped with on described three insulators to be flexible coupling, and described installation shaft is connected with a deciliter handle.
As further improvement of the utility model, described insulator adopts SF
6Or silicone grease is made.
The beneficial effects of the utility model are, separator is set and separator is built in the housing of high voltage load switch, so that product reliable circuit at disjunction leading-out terminal place when maintenance or segmentation have a power failure has guaranteed staff's safety.And the utility model exists simple in structurely, and volume is little, is convenient to the advantages such as the installation of product and maintenance.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure, 1, housing; 11, housing inner chamber; 2, deciliter handle; 3, end of incoming cables; 4, leading-out terminal; 5, separator; 51, installation shaft; 52, insulator; 6, be flexible coupling.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By shown in Figure 1, a kind of high-voltage alternating demarcation load switch, comprise housing 1 and deciliter handle 2, described housing 1 is provided with end of incoming cables 3 and leading-out terminal 4, being provided with in the described housing 1 can be at the separator 5 of housing inner chamber 11 rotations, described separator 5 is provided with separator 5 is connected and is flexible coupling 6, and described 6 one ends that are flexible coupling are fixedly connected with end of incoming cables 3, and the other end and leading-out terminal 4 are flexibly connected.Specifically, described separator 5 comprises installation shaft 51 and three insulators 52 that are sheathed on the installation shaft 51, is equipped with on described three insulators 52 to be flexible coupling 6, and described installation shaft 51 is connected with deciliter handle 2.In particular, described insulator 52 adopts SF
6(sulphur hexafluoride) or silicone grease are made.In particular, described be flexible coupling 6 be flexible coupling for copper.The beneficial effects of the utility model are, separator is set and separator is built in the housing of high voltage load switch, so that product reliable circuit at disjunction leading-out terminal place when maintenance or segmentation have a power failure has guaranteed staff's safety.And the utility model exists simple in structurely, and volume is little, is convenient to the advantages such as the installation of product and maintenance.
Every technical staff's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
