2. the wiring inconvenience of thyristor module and cabinet must install to thyristor earlier on the cabinet, and wiring in narrow space again is difficult to operation;
3. when thyristor module is heavier, bring very big difficulty to dismounting;
4. for guaranteeing the insulation distance between the thyristor module, cabinet must be done very greatly, has increased manufacturing cost;
5. thyristor module structure disunity;
6. thyristor is safeguarded inconvenience, when replacing the damage thyristor, is easy to cause the damage of peripheral circuits, inefficiency, and on-the-spot interruption duration is long.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide that a kind of volume is little, good looking appearance, thyristor module and supervisory circuit easy accessibility thereof, be convenient to the mesohigh soft starting cabinet safeguarded efficiently.
Problem of the present invention realizes with following technical proposals:
A kind of mesohigh soft starting cabinet of being convenient to safeguard, comprise cabinet in the formation, be loaded on identical thyristor module of the interior a plurality of structures of cabinet and the modular insulating support that is used for fixing thyristor module, described modular insulating support is made up of drawer-like support body and a plurality of drawer-like module carrier; Described drawer-like module carrier front end is provided with handle, and the rear end is provided with and is installed on the moving contact that the fixed contact on the drawer-like support body rear wall is complementary, and its lower sidewall is provided with bearing; Described thyristor module comprises resistance, the electric capacity in thyristor and circuits for triggering and the resistance capaciting absorpting circuit, and they all are installed on the base plate of drawer-like module carrier, and described thyristor is connected with moving contact by copper bar.
The above-mentioned mesohigh soft starting cabinet of being convenient to safeguard, described drawer-like support body is made up of top board, rear wall, spacing sidewall and multi-layer drawers supporting plate, adjacent two layers drawer supporting plate or upper strata drawer supporting plate and top board and two spacing sidewalls surround drawer-like module carrier slot, leave the heat radiation gap between the spacing sidewall of described drawer-like support body and the rear wall.
The above-mentioned mesohigh soft starting cabinet of being convenient to safeguard, between the base plate of described drawer-like module carrier and the wall, be connected by angle aluminium between the adjacent wall, between described spacing sidewall and drawer supporting plate and the top board, all be connected between rear wall and drawer supporting plate and the top board by angle aluminium.
The present invention is fixed in thyristor module in the modular insulating support that insulating material makes, drawer-like module carrier and drawer-like support body guarantee safe distance the time, can dwindle the cabinet volume greatly.Thyristor module all is a plug-in type to the wiring of cabinet, and the dismounting and change thyristor module is very convenient, has shortened the interruption duration when safeguarding greatly.Under the drawer-like module carrier bearing is installed, it is more easily laborsaving to make plug that the drawer-like module carrier of thyristor module is housed, and has reduced operator's labour intensity.Thyristor module adopts modularization to install, and is more attractive in appearance than existing mesohigh soft starting cabinet, and is convenient to safeguard.Not only volume is little in the present invention, good looking appearance, and dismounting and easy to maintenance, can improve maintenance work efficient greatly, shortens on-the-spot interruption duration.
The invention will be further described below in conjunction with accompanying drawing.
