Abstract
The invention discloses an isolation trolley with a contact temperature measuring function. The isolation trolley comprises a chassis, an installation base arranged on the chassis, two contact arms which are connected with the installation base and arranged symmetrically up and down, and contacts arranged at ends of the two contact arms. The two contact arms are provided with temperature sensing probes close to the contacts. In order to prevent deficiencies of the isolation trolley of a 10-kV indoor metal armored drawout switch device in normal operation, the temperature rise of the contacts of the isolation trolley is detected in real time, and the 10-kV indoor metal armored drawout switch device operates normally.
Description
Technical field
The present invention relates to a kind of isolation trolley with the contact temperature measurement.
Background technology
The extensive use of 10kV indoor metal armoring draw out switchgear, because its enclosed construction, after in its use procedure isolation trolley being entered the service position, can not measure, observe the electric current of isolation trolley, larger or insert when contact is bad behind the service position when loop current, can produce contact temperature too high and burn out the situation of contact, and cause loop fault.
Summary of the invention
Main purpose of the present invention is to provide a kind of isolation trolley with the contact temperature measurement of protecting power grid security.
For addressing the above problem, the present invention adopts following technical scheme: a kind of isolation trolley with the contact temperature measurement, comprise chassis vehicle, and be arranged on mount pad on the chassis vehicle, and link to each other with mount pad, symmetrically arranged two contact arms up and down, and be arranged on the contact of two contact arm ends, on described two contact arms and be positioned at contact near be provided with temperature-sensing probe.
Further, the centre position of described two contact arms is provided with insulating cover.
Further, the described isolation trolley of measuring with contact temperature also comprises the temperature measuring equipment that inserts for for contact.
The beneficial effect of the isolation trolley that band contact temperature of the present invention is measured is: for defects appears in the isolation trolley that prevents the 10kV indoor metal armoring draw out switchgear when normally moving, detect in real time the temperature rise situation of isolation trolley contact, guarantee that the 10kV indoor metal armoring draw out switchgear normally moves.
Description of drawings
Fig. 1 is the schematic diagram of the isolation trolley of band contact temperature measurement of the present invention.
Embodiment
See also shown in Figure 1, a kind of isolation trolley with the contact temperature measurement of the present invention, comprise chassis vehicle 6, and be arranged on mount pad 4 on the chassis vehicle 6, and, up and down symmetrically arranged two contact arms 24 that link to each other with mount pad, and be arranged on the contact 1 of two contact arm 2 ends, on described two contact arms 2 and be positioned at contact 1 near be provided with temperature-sensing probe 5.
The centre position of described two contact arms 2 is provided with insulating cover 3.The described isolation trolley of measuring with contact temperature also comprises the temperature measuring equipment 7 that inserts for for contact 1.
The chassis structure that this isolation trolley adopts is consistent with the circuit breaker trolley chassis structure of actual motion; The circuit breaker of isolation trolley adopts analogies to replace.The circuit breaker trolley of the structure of isolation trolley, size and installation site and actual motion is in full accord.When being inserted into the service position, respond to the temperature data of each contact 1 at isolation trolley by each temperature-sensitive head, through wireless transmission method, be sent on the main display floater of temperature measuring equipment 7.Operating personnel can observe by the observation window on the isolation trolley Temperature numerical of each contact, thereby judge whether isolation trolley produces the problems such as overcurrent or loose contact.
Because isolation trolley must pass through loop current, by observing contact 1 temperature variations of isolation trolley after being pushed into the service position, whether the contact arm 2 of observing isolation trolley has the situations such as overheated and loose contact in running.The Temperature numerical of the contact arm 2 by observing isolation trolley prevents that one-time contact from seriously burning out accident because of the loose contact generation.
The beneficial effect of the isolation trolley that band contact temperature of the present invention is measured is: for defects appears in the isolation trolley that prevents the 10kV indoor metal armoring draw out switchgear when normally moving, detect in real time the temperature rise situation of isolation trolley contact, guarantee that the 10kV indoor metal armoring draw out switchgear normally moves.
The above be the specific embodiment of the present invention only, but protection scope of the present invention is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
