Abstract
The utility model relates to a main circuit connector of a drawer type switch cabinet for drawing a unit, which consists of an insulating casing, a conducting body, and a fastener. The main circuit connector with a temperature controller of the utility model is characterized in that the temperature controller is arranged on the side of the conducting body, and a pair of conducting wires is led out by the contact point of the temperature controller, and connected with an external control electric appliance, if the connector with the structure appears the overload phenomenon in the power on running, when the temperature of the conducting body is risen to the controlled value, the temperature controller can automatically send out a control signal, thereby urging the electricity power net system to make the corresponding control, and achieving the purpose of removing the trouble and avoiding the loss in time.
Description
Technical field
The utility model relates to a kind of main circuit connector that the draw out switchgear cabinet is extracted the unit out that is used for.
Background technology
The present main circuit connector that generally uses, structure and shape have varied, but basic comprising is formed by insulation crust, electric conductor and securing member, one utmost point connector or multipole connector are arranged, yet these connectors all exist following shortcoming: in that energising is in service when causing the electric-conductor excessive heating if the overload phenomenon occurs, just can burn connector, the property loss that causes the electric power system fault and cause thus.
The innovation and creation content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, provide a kind of when the energising operation controlled temperature of testing conductive spare automatically, play the connector of overload protective function.
The purpose of this utility model is achieved in that a kind of main circuit connector with thermostat, form by insulation crust, electric conductor and securing member, insulation shell comprises operating room and fastening chamber, electric conductor comprises contact and terminal block, the contact of electric conductor is positioned at the operating room of insulation shell, one end of terminal block is connected with contact, one end is positioned at outside the insulation shell, mid portion is positioned at the fastening indoor of insulation shell, this connector has a utmost point connector or multipole connector, it is characterized in that: be provided with thermostat on the electric conductor next door.
The main circuit connector of such scheme is characterized in that: the main circuit connector is provided with thermostat in utmost point connector electric conductor next door therein, also can thermostat be set respectively on the terminal block next door of multipole electric conductor.
The main circuit connector of such scheme is characterized in that: the contact of thermostat can outwards be drawn couple of conductor separately, also can outwards draw couple of conductor after connecting by the lead that draw respectively the contact of several thermostats.
The beneficial effects of the utility model
Because the position at the close electric conductor of main circuit connector is provided with thermostat, the lead of being drawn by the contact of thermostat is connected with the control apparatus of external electrical network system, when the electric conductor temperature rise reaches controlled value, thermostat just can send signal automatically, impel network system to make control corresponding, reaching in time fixes a breakdown avoids the purpose of losing.
Description of drawings
Fig. 1 is the structural representation of prior art main circuit connector.
Fig. 2 is the structural representation of the main circuit connector of the utility model band thermostat.
Fig. 3 is the A-A profile of Fig. 2.
Fig. 4 is the structure enlarged diagram of thermostat of the present utility model.
Specific embodiment
As seen from Figure 1, the general main circuit connector of Shi Yonging, form by insulated electric conductor 1, electric conductor 2 and securing member 3, except a utmost point connector is arranged, three utmost point connectors or four utmost point connectors etc. also can be arranged, and these connectors are not provided with thermostat, and are in service if the overload phenomenon occurs in energising, will cause the electric-conductor excessive heating and burn connector, even the property loss that causes the electric power system fault and cause thus.
From Fig. 2 to Fig. 4, can see, the main circuit connector of the utility model band thermostat, include insulation shell a, electric conductor b, thermostat c and securing member d, insulation shell a comprises the a1 of operating room, fastening chamber a2, electric conductor b comprises contact b1, terminal block b2, thermostat c comprises shell c1, temperature control spare c2, contact c3 and connection lead c4, the contact b1 of electric conductor b is positioned at the a1 of operating room of insulation shell a, terminal block b2 one end of electric conductor b is connected with contact b1, one end is in the outside of insulator a, use as external cable, mid portion is positioned at the fastening chamber a2 of insulation shell a, moving range with restriction electric conductor b, thermostat c is arranged near electric conductor terminal block b2 place, the contact c3 of every thermostat can draw two lead c4 separately and be connected with outside electrical equipment, and also two leads every thermostat contact can being drawn are connected with the contact of adjacent thermostat, and the contact of two ends, series connection back thermostat is respectively drawn a lead and used for outside control apparatus connection.
The main circuit connector of the utility model band temperature control part is in energising operation work, if the electric current by electric-conductor is during greater than the rated operational current of electric-conductor, the temperature rise of electric conductor just can increase, when its temperature arrives specified temperature control value, temperature control spare c2 just can bring into play control action, impels the contact c3 of thermostat to change state, and this change impels control apparatus to make corresponding work simultaneously, in time to fix a breakdown, avoid causing the generation of more major break down.
Claims (3)
1, a kind of main circuit connector with thermostat, comprise insulation shell, electric conductor and securing member, insulation shell comprises operating room and fastening chamber, and electric conductor comprises contact and terminal block, and the contact of electric conductor is positioned at the operating room of insulation shell, one end of terminal block is connected with contact, one end is positioned at outside the insulation shell, and mid portion is positioned at the fastening indoor of insulation shell, it is characterized in that: be provided with thermostat on the electric conductor next door.
2, the main circuit connector of band thermostat according to claim 1 is characterized in that: the main circuit connector is provided with thermostat in utmost point connector electric conductor next door therein, also can thermostat be set respectively on each utmost point electric conductor next door of multipole connector.
